Introduction to The 2020 Census Local Update of Census Addresses Operation

1. Background

The 2020 Census Local Update of Census Addresses Operation (LUCA) is a voluntary decennial census operation. LUCA is the only opportunity prior to the 2020 Census for tribal, state, and local governments (including the District of Columbia and Puerto Rico) to review and update the Census Bureau’s residential address list for their jurisdiction. The Census Bureau relies on a complete and accurate address list to reach every living quarters and associated population for inclusion in the census. The Census Address List Improvement Act of 1994 (Public Law 103-430) authorizes the LUCA operation. Refer to <https://www.census.gov/geo/partnerships/luca-pl-103-430.html> for more information.

Title 13, United States Code (U.S.C.), provides for the confidential treatment of address information and structure points showing the location of housing units or group quarters. For more information about Title 13, U.S.C., please refer to <https://www.census.gov/history/www/reference/privacy_confidentiality/title_13_us_code.html>. Signed confidentiality agreements and restrictions are required to participate in LUCA. See Appendix A, Confidentiality and Security Guidelines or refer to <https://www.census.gov/programs-surveys/decennial-census/about/luca.html>.

2. LUCA Responsibilities

1. Before You Begin Your Review

Chapter 1 explains some of the terms and concepts used by the Census Bureau and recommended strategies for your LUCA review. Refer to the Glossary or visit the Census Bureau’s Web site at <https://www.census.gov/geo/reference/> for additional terms and definitions.

1. The Census Bureau’s Master Address File

The Master Address File (MAF) is a nationwide database of all addresses used to support many of the Census Bureau’s operations. Besides containing mailing addresses and ZIP Codes, an address record in the MAF also contains geographic information about the location of addresses. In areas where there are non-city style addresses (e.g., rural route or post office box number), the address record may contain additional information such as a location description.

2. The Topologically Integrated Geographic Encoding and Referencing Database

Address records in the MAF link to road segments or road features in the Topologically Integrated Geographic Encoding and Referencing (TIGER) database. The TIGER database includes the geographic coordinates and names of all streets, water features, and other linear features, and boundaries for jurisdictions and statistical areas (census tracts², census blocks³, etc.) used to tabulate decennial census data.

3. What is a Housing Unit?

The Census Bureau defines a housing unit as:

A single-family house, townhouse, mobile home, trailer, apartment, group of rooms, or a single room occupied as a separate living quarters or, if vacant, intended for occupancy as a separate living quarters. Separate living quarters is one in which one or more occupants (or intended occupants, if vacant) live separate from any other individual(s) in the building and have direct access to the living quarters without going through another living quarters, such as from outside the building or through a common hall.

The following types of housing units are acceptable and should be included on the updates to the Census Bureau’s Address List that you submit:

• Houses, including townhouses, condominiums, and apartments.

• Living quarters within an otherwise nonresidential structure such as an apartment within a church, school, or business.

• Mobile homes or trailers occupied as separate living quarters, or if vacant, intended for occupancy as separate living quarters.

• Transitory location (TL) sites for movable or mobile housing, portable housing units, boats, motorized recreational vehicles (RVs), tents, trailers that are pulled by cars or trucks. See Section 4.4.

• Any housing units under construction that will be habitable (closed to the elements with final roof, windows, and doors) on Census Day, April 1, 2020.

4. What are Group Quarters?

Group Quarters (GQs) are a place where people live or stay, in a group living arrangement owned or managed by an entity or organization providing housing and/or services for the residents. This is not a typical household-type living arrangement. These services may include custodial or medical care as well as other types of assistance, and residency is commonly restricted to those receiving these services. Residents of group quarters are usually not related.

The following types of group quarters are acceptable and should be included on your updated address list:

• Correctional facilities:

• Federal and state prisons.

• Local jails and other municipal confinement facilities.

• Correctional residential facilities.

• Group homes.

• Juvenile facilities:

• Group homes for juveniles (non-correctional).

• Residential treatment centers for juveniles (non-correctional).

• Correctional facilities intended for juveniles.

• Nursing homes:

• Nursing facilities/skilled-nursing facilities.

Note: Residents of assisted living, congregate care, and continuing care communities who are not receiving skilled nursing care are included in the housing unit population. Assisted living quarters are considered housing units and not group quarters as long as they have separate access from outside or from a common hall.

• Homeless shelters.

• Hospitals:

• Mental (psychiatric) hospitals and psychiatric units in other hospitals.

• Hospitals with patients who have no usual home elsewhere.

• In-patient hospice facilities.

• College or university dormitories, fraternities, sororities.

• Workers’ group living quarters or dormitories.

• Religious group quarters.

• Any group quarters under construction that will be habitable (closed to the elements with final roof, windows, and doors) on Census Day, April 1, 2020.

Note: Housing units and group quarters can exist within the same structure. For example, assisted living quarters (housing units) may be located in the same structure that contains a nursing facility (group quarters).

5. Unacceptable Types of Housing Units and Group Quarters

Exclude the following unacceptable types of housing units and group quarters addresses from your updates to the Census Bureau’s Address List:

• Condemned or scheduled for demolition.

• Under construction or remodeling for conversion to a nonresidential purpose.

• Used solely for nonresidential storage.

• Used solely as offices or businesses in which no one is living.

• Used solely for ceremonial purposes.

• Transitory units (TU) including pads, sites, slips, units, and rooms located at transitory locations (TL). See Section 4.4.

• Under construction and will not be habitable (closed to the elements with final roof, windows, and doors) on Census Day, April 1, 2020.

Note: The LUCA materials do not contain residential addresses within military installations. The Department of Defense provides the enumeration numbers to the Census Bureau for those living on military bases. The Census Bureau does not canvass or mail to addresses on military installations so there is no need to include these addresses as part of the LUCA review.

6. Census Bureau Addresses

The Census Bureau divides all addresses into two use types, residential and nonresidential.

1. Residential and Nonresidential Addresses

Residential addresses are addresses of housing units and/or group quarters where one or more people could live. Nonresidential addresses are addresses of a structure or unit within a structure that do not serve as a residence, such as commercial establishments, schools, government offices, and churches.

Note: Some structures can contain both residential and nonresidential units, even though they have a single address such as an apartment over a store or a home with an office. In this instance, the LUCA operation considers this address residential since it contains a housing unit.

2. City Style Address Format

The Census Bureau classifies housing units and group quarters that have one of the following address types as city style addresses.

General address—A general address type contains a minimum of a house number, street name, and a ZIP Code. For example, 212 Ave Muñoz, 00099 OR 2 Cll Lopez, Unit A, 00098. Sometimes an additional piece of information is required to complete the address. For example, 6668 Cll Lopez BDA San Luis, 00099.

Apartment complex address—An apartment complex type address contains, at a minimum, an apartment/condominium/public housing complex (residencial), apartment unit, and a ZIP Code. For example, Cond del Mar, Apt 3A, 00099 OR Res Día Nueva, 222, 00098. Frequently, an address number and street name are available for the apartment complex address. For example, 87 Cll Sabanetas, Cond Jardín de Rosas, Apt 101, 00098.

Urbanización address—An urbanización type address contains at a minimum an urbanización name, address number, and ZIP Code. For example, Urb San Antonio, 121, 00099 OR Urb Los Domingos, B-3, 00098. Generally, a street name is also available for the urbanización address. Please provide the street name if available. For example, Urb Los Lobos, 126 Cll 5, 00098.

City style addresses for housing units in multiunit structures, such as apartment buildings, contain a unit designator, for example, Apt 101 or Suite D or a location designator such as “rear” or “basement” (Refer to Appendix E, Unit Designation Abbreviations). The Census Bureau and the United States Postal Service (USPS)
treat these designators as part of the housing unit address, and they are included
in each affected census address record.

Note: For 2020 LUCA, participants must provide unit identifiers (e.g., Apt 1, Apt 2, Unit A,
Unit B) for multiunit buildings. Ensure that all your apartment buildings, especially small multiunit buildings (3-4 units), such as large houses subdivided into apartments, have a separate address line for each unit that includes the basic street address and the individual unit designation.

3. Non-city Style Address Format

The Census Bureau classifies addresses that do not meet the minimum requirements in Section 1.6.2 City Style Address Format as non-city style addresses. Non-city style addresses also may have an incomplete house number and street name address. Frequently used non-city style mailing addresses include:

• Rural route and box number.

• Highway contract route and box number.

• General delivery.

• Post Office box only delivery (Not accepted for LUCA).

Non-city style addresses often do not follow any numeric sequence and may not be associated with the name of the street or highway on which they are located. For this reason, the Census Bureau uses different methods to compile the list of addresses for inclusion into the address list, such as a physical location description (BRICK HOUSE w/ATTACHED GARAGE ON RIGHT), structure points (geographic coordinates), and census geographic codes (state code, county code, census tract number, census block number).

7. Census Tract

Census tracts are small, relatively permanent statistical subdivisions of a county or statistically equivalent entity (such as municipios in Puerto Rico). Numbered uniquely within each county, census tracts:

• Delineated for presenting Census Bureau statistical data.

• Generally, have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people.

• Follow relatively permanent visible features.

• May follow governmental unit boundaries and other non-visible features.

• Occasionally split due to population growth or merged because of substantial population decline.

• Consists of a six-digit code with a decimal between the fourth and fifth digit, contains a four-digit base number, including leading zeroes, plus a two-digit number suffix, with trailing zeroes. For example, 1234.01 and 0003.00.

8. Census Block

A geographic area bounded by visible features, such as streets, roads, streams, and railroad tracks, and invisible features, such as the boundaries of governmental units and other legal entities. A census block is the smallest area for which the Census Bureau collects and tabulates statistical information. Census blocks are numbered within census tracts and are unique to the census tract in which they belong. For example, if your jurisdiction has three different census tracts then each will likely contain a census block 1000. Pay close attention to both the census tract and census block number on the address list when conducting your review and making updates.

Note: The 2020 LUCA operation uses 2010 tabulation blocks represented as “tabblock2010” in the TIGER Partnership shapefiles for digital map participants.

9. What is Geocoding?

In order to process your address submissions, the Census Bureau requires the inclusion of census geographic code information (geocodes). Geocoding is the assignment of an address or structure to a location identified by one or more geographic codes. Geographic codes include the correct state, county, census tract, and census block codes.

Because the Census Bureau counts people where they live, geocodes support the systematic collection of data that allows Census enumerators to locate an address. They are also important in allocating data from questionnaire responses to the correct location. You must include geocode information or structure coordinates (latitude and longitude) for the Census Bureau to process your address submissions. The Census Bureau will not accept addresses without either the geocode including the state, county, census tract, and census block codes or by providing structure coordinates (latitude and longitude) on the address list. You can find the census geographic codes on your LUCA materials.

10. Ungeocoded Addresses

The USPS provides addresses to the Census Bureau on a regular basis. Although these addresses include state and county codes, the Census Bureau further geocodes these addresses to include the census tract and census block. In some cases, where the Census Bureau does not have new roads or road names in TIGER, these addresses could remain ungeocoded to the correct census tract or block. The Census Address List for state and county participants may contain ungeocoded addresses that could indicate areas of new growth where the Census Bureau may be missing the corresponding road features. Please provide the geocodes or the structure coordinates (latitude and longitude) for these addresses, if known, to ensure that the Census Bureau can enumerate each housing unit in the correct location.

11. Strategies for Reviewing the Census Bureau’s Address List

When deciding how to conduct the LUCA review, consider your time, staff, and available local address information. If a complete review is not possible, focus your review on these areas:

• Annexed land.

• Apartment buildings and complexes.

• Areas along governmental boundaries.

• Areas of new housing construction (apartment complexes/subdivisions).

• Blocks with the greatest address count differences between the Census Bureau’s address block count and your address block count.

• E-911 address conversion areas.

• Group Quarters (e.g., housing such as college dorms, and nursing homes).

• New mobile home parks or new scattered mobile homes.

• Single-family homes converted to multifamily homes, and vice versa.

• Warehouses converted to residential lofts.

Note: New for the 2020 LUCA Operation, multiunit identifiers (i.e., Apt 1, Apt 2, or Unit 1,
Unit 2) are required for all newly added addresses and address updates for multiunit structures. The Census Bureau will not process multiunit addresses without multiunit identifiers.

12. Local Address Sources

There are many possible sources of local address information. Some of these sources may not match the Census Bureau’s Address List exactly, but they are a good indication of where change is taking place and can help you identify addresses that you need to add to the Census Address List.

Potential local address sources for compiling your residential address list:

• Annexation records.

• Assessment or tax files (residential units).

• Driver’s license files.

• E-911 address files.

• Housing inspection records or occupancy permits.

• Local utility records.

• New housing construction or building permits (include units that are under construction only if final roof, doors, and windows will be in place on Census Day, April 1, 2020).

• Planning and zoning records.

• School enrollment records.

• Voter registration files.

2. The LUCA Digital Address Materials

This chapter discusses protecting Census Bureau address information and describes the Census Bureau’s digital address materials. All address list and map examples containing map spots use fictitious information.

1. Protecting Census Bureau Address Information

The most efficient method to review and match your local address file to the Census Bureau’s address file is to copy the Census Bureau’s digital address file onto a computer hard drive. You must first ensure the protection of the Census Bureau’s
Title 13, U.S.C. address information including your Census Bureau digital address file, all address list paper copies, and maps (including copies) containing structure points (map spots). For detailed information refer to Appendix A, Confidentiality and Security Guidelines.

If you need to add additional reviewers during your LUCA review, a blank D-2005(SP) Confidentiality Agreement Form is included in Appendix G. Be sure additional reviewers have read and understand the Confidentiality and Security Guidelines, Appendix A, before signing and returning the D-2005(SP) Confidentiality Agreement Form to the Census Bureau.

Any Information Technology (IT) systems used for LUCA participation must be accessible only to those who signed the D-2005(SP) Confidentiality Agreement Form. Your IT system should restrict the read, write, and delete functions to all Title 13 materials.

1. General Guidelines

• Construct electronic security profiles to allow only the LUCA liaison and the LUCA reviewers to access Title 13 materials. Test your security to ensure that access is restricted.

• Use file encryption and passwords to protect all digital Title 13 materials at all times. Encrypt files using the Advanced Encryption Standard (AES) with key length of 256 bits.

• Do not leave open computers containing Title 13 materials unattended. Log-off computers or lock the room.

• Label all digital media and every printed page of any paper materials produced from Title 13 electronic media with the following:

• “This document contains information, the release of which is prohibited by Title 13, U.S.C., and is for U.S. Census Bureau official use only. Wrongful disclosure or release of information can be punished by fine or imprisonment (Public Law 99-474)” <https://www.census.gov/history/www/reference/privacy_confidentiality/title_13_us_code.html>.

• Do not send the backup media off-site. Store Title-13 materials in a secured area. Do not mix, store, or back-up LUCA data with other data.

• Clear dedicated media containing Title 13 materials before reuse. Overwrite Title 13 digital data a minimum of three times using a commercial disk utility program.

• Do not disclose precise or even anecdotal information about Census Bureau addresses or locations to anyone who has not signed the D-2005(SP) Confidentiality Agreement Form.

2. Password Guidelines

The IT systems must use log-on routines that require a user-ID and password that conform to the following guidelines:

• Unique user-ID and password required for the LUCA liaison, the LUCA reviewers, and anyone who has signed the Confidentiality Agreement.

• Must consist of at least 12, nonblank characters consisting of at least one alphabet letter and either one number or one special character (i.e., $,*, or &).

• Reject passwords that are the same as the user-ID or used within the last six months.

• Disable passwords after three failed attempts.

• Mask passwords.

• Require password changes every 90 days or immediately, if compromised.

• Require user to change an assigned password to a unique password the first time the user accesses a new account.

2. File Names for State and County Governments

The digital address list file contains all of the residential addresses currently recorded by the Census Bureau for your jurisdiction. The digital address count list file contains the residential address counts for each census block within your jurisdiction. The file names contain your unique Federal Information Processing Series (FIPS) code for your jurisdiction. The name of each of the files is:

1. Address List: 2020LUCA _<EntityID>_address_list.csv, where <EntityID> is XXyyyyy. Where XX is the two character, alpha entity type represented as follows:

• ST—Puerto Rico

• CO—County (Municipio)

And where yyyyy is a variable length, numeric entity ID code represented as follows:

• State—Puerto Rico: 2 digits

• County—Municipio: 5 digits

2. Address Count List: 2020LUCA_XXyyyyy_address_countlist.csv.

Table 2: Entity Identification Codes

Entity	Entity Identification Code	Total Characters
Puerto Rico	ST (2 alpha) + (2 numeric)	4
Municipio	CO (2 alpha) + State (2 numeric) + County (3 numeric)	7

1. File Name Examples

The following two sections provide examples for the address list and address count list file names.

1. Address List File Names

4-character state file name–ST72 (Puerto Rico):

• 2020LUCA_ST72_address_list.csv, where “ST” is state and “72” is the state code for Puerto Rico.

7-character county file name–CO72035 (Cayey Municipio, Puerto Rico):

• 2020LUCA_ CO72035_address_list. csv, where “CO” is county, “72” is the state code for Puerto Rico and “035” is the county code for Cayey Municipio.

2. Address Count List File Names

The address count list file follows the same naming convention as the address list file but uses “_address_countlist.csv.” Because the naming convention is identical to the address list file for each entity type, there is no need to repeat all examples. The example below provides the address count list file name for a 7-character county – Cayey Municipio, Puerto Rico:

• 2020LUCA_CO72035_address_countlist. csv, where “CO” is county, “72” is the state code for Puerto Rico, and “035” is the census county code for Cayey Municipio.

2. The LUCA Materials Digital Files

3. Creating a Working Copy of the LUCA Digital Files

The Census Bureau recommends that you make a copy of each of the original files and place them on the hard drive of a computer that is password protected. This will preserve the originals should you need to look at an original record or require another original copy of the file.

1. The Digital Address List

Note: A case-sensitive password is required to open the Address List file. The Census Bureau mailed the password to you, separately from your LUCA materials.

To keep your work organized, create a new directory or new folder on your hard drive.

• Insert the Title 13 Data Disc.

• One of the following screens opens depending on your product preference selection.

Figure 1. Title 13 Data Disc Screen for Digital Address List and Large Format Paper Maps

4. Converting Comma Delimited Text Files

The .csv files that extract from .exe actions described in Section 2.2 are comma delimited text files. Most commercial spreadsheet and database programs can open the LUCA files (e.g., Microsoft Excel, Microsoft Access,3F⁴ etc.).

In order to read the file contents properly, you need to import the file rather than opening it. This example uses Excel 2016.

• Open a new Excel spreadsheet.

Figure 11. Importing a File in Excel

• Select ‘Data’. Click on ‘Get External Data.’ Select ‘From Text’ (Figure 11).

• Navigate to the address list file you extracted and click on the file.

• When the file highlights, select ‘Import’ at the bottom of the screen (Figure 12).

Figure 12. Selecting the Address List File

• The ‘Text Import Wizard’ window opens in Excel. Step 1 of 3, select ‘Next’ (Figure 13).

Figure 13. Text Import Wizard Step 1

• Step 2 of 3, select the ‘Comma’ box. From the ‘Text qualifier’ drop-down menu, select ‘{none}’. Select ‘Next’ (Figure 14).

Figure 14. Text Import Wizard Step 2

• Step 3 of 3, hold down the ‘Shift’ key and scroll to the end of the fields. The fields will highlight black.

• Select the ‘Text’ radio button.

• Click ‘Finish’ at the bottom of the window (Figure 15).

Figure 15. Text Import Wizard Step 3

Note: Define all field types as text, including numeric fields such as census tract number, census block number, GEOID, ZIP Code, and so forth to account for leading zeros that are important for accurate coding.

Once the address list opens, follow the record layout in Table 3: Digital Address List Record Layout to name and define the sizes of your fields.

3. The File Layouts

The following two sections provide the file layouts for the address list and the address count list.

1. Census Bureau’s Address List

The Census Bureau’s Address List contains all of the residential (city style and non-city style) addresses known to the Census Bureau within your jurisdiction. It also contains census geographic codes (state, county, census tract, census block) that indicate the location of each address.

Each address record in the address list file is a maximum of 933 characters and contains 30 fields of information. The character length of each record may vary. The first row, or header row, of the address list file displays the field names for each data field in the file.

Each address record contains the following fields that you may or may not edit on the Census Address List’s existing addresses:

1. LINE_NUMBER—Sequential number for each address record in the file. Do not edit this field.

2. MAFID—Unique control number (maximum character length is 9 characters) assigned to each MAF address by the Census Bureau. Do not edit this field.

3. ENTITYID—Unique identification number (maximum character length is 12 characters) assigned by the Census Bureau to each entity. Do not edit the Entity ID Code for existing address records, but record your Entity ID Code when you add address records.

2. Address Count List

The Address Count List contains the number of housing unit (HU) and group quarters (GQ) addresses on the Census Bureau’s Address List for each census block within your jurisdiction. This list is for reference purposes only. Participants can use this list to see the number of residential addresses the Census Bureau has for each block and determine if those numbers are correct. The first row, or header row, displays the field names for each data field in the file. In order to join the data using GIS, digital users should plan to remove the spaces in the field names.

Although developed for use with Geographic Update Partnership Software (GUPS), you may use the digital Address Count List file for your reference. The Original Count of HUs, the Current Count of HUs, and the Difference IN HUs fields contain the same number of addresses. Likewise, the Original Count of GQs, the Current Count of GQs, and the Difference of GQs fields contain the same number. The Local Count of HUs and Local Count of GQs contain zeros.

Each file contains the following information:

1. STATE—Two-digit current state FIPS code for your jurisdiction.

2. COUNTY—Three-digit current county FIPS code for your municipio.

3. TRACT— Consists of a six-digit code with a decimal between the fourth and fifth digit, contains a four-digit base number, including leading zeroes, plus a two-digit number suffix, with trailing zeroes. For example, 1234.01 and 0003.00.

4. BLOCK—Four-digit 2010 Census Tabulation Block Number. Census blocks are numbered uniquely from 0000 to 9999 within a census tract, which nest within a county and a state. The first digit of the census block number identifies the block group.

5. GEOID—15-digit combination of STATEFP, COUNTYFP, TRACT, and BLOCK fields. For example, 010090046001002.

6. Original_Count_of_HUs—Total number of addresses in your jurisdiction identified as residential housing units by data in the MAF.

7. Current_Count_of_HUs—Number is the same as the Original Count of HUs. (For use with GUPS).

8. Local_Count_of_HUs—Contains zeros. (For use with GUPS).

9. Difference_in_HUs—Contains the same number as the Original Count of HUs field. (For use with GUPS).

10. Original_Count_of_GQs—Total number of addresses in your jurisdiction identified as residential group quarters by data in the MAF.

11. Current_Count_of_GQs—Number is the same as the Original Count of GQs. (For use with GUPS).

12. Local_Count_of_GQs—Contains zeros. (For use with GUPS).

13. Difference_IN_GQs—Contains the same number as the Original Count of GQs. (For use with GUPS).

Table 4: Digital Address Count List Record Layout contains the maximum character length for each field. At the end of the file, the GEOID field contains the phrase “Unable to Geocode.” This data is for state and county participants that may receive ungeocoded addresses as part of their LUCA materials. For other participants, this line contains zeros.

The last row of the file, the GEOID field contains the word “TOTAL.” This row records the total number the Census Bureau has for your jurisdiction in these fields:

• ORIGINAL_COUNT_OF_HUs.

3. The LUCA Paper Maps

To support the LUCA paper map selection, the Census Bureau provides:

• Large format paper maps (36”x32”), which may include one or more sheets. The Census Bureau provides large format paper maps to all participants that selected the Paper or Paper/PDF product preference for the map selection. Use these maps to geocode your addresses.

• The focus of the 2020 LUCA operation is addresses. While helpful, map updates are only required to indicate new, or updates to existing, non-city style address records. Participants choosing the paper address list/large format paper product preference that wish to make map updates to accompany their address list updates, must use the large format maps since they do not receive the small format block maps. Due to the scale of the large format maps, updates may be difficult. Please do not allocate much of your 120-day review period attempting map updates. Focus on the address list.

• DVD of small format (8.5”x14”) block maps in Adobe Portable Document Format (PDF) that contains map spots (address structure coordinates showing the location of residential addresses). Only those participants that selected the large format paper map with PDF materials receive the Title 13 small format block maps. A PDF of the large format maps is included with this product preference.

• Block to Map Sheet Relationship List that lists all of the census blocks within your jurisdiction and identifies the large format parent map sheet(s) on which each census block is located.

See Appendix B for a detailed explanation of the legend for the large format paper map.

1. Understanding a Large Format LUCA Paper Map

There are three types of paper map sheets:

1. Index Sheets

2. Parent Sheets

3. Inset Sheets

1. Index Sheets

• Covers the entire extent of your jurisdiction.

• Divided into numbered grids that correspond to the parent sheets.

• Each numbered grid area corresponds to the area covered by a parent sheet.

• Provided to jurisdictions with more than one parent sheet.

• Index sheets are for reference purpose only.

2. Parent Sheets

• Detailed view of a section of your jurisdiction.

• Corresponds to a grid and grid number on the Index sheet.

• Shows detail for features and geographic areas.

• Identifies the location of census tracts and blocks within your jurisdiction.

Note: Blocks affected by boundary improvements may contain a block number with an alpha suffix on the parent sheet and/or inset map. You do not need to provide the alpha suffix when changing a geocode on the address list or adding a geocode to a new address.

3. Inset Sheets

• Do not exist for every jurisdiction or on every parent sheet.

• Shows the detail of congested areas on parent sheets.

• Highlighted on the parent sheet with a fill pattern and identified with an alpha
  character (e.g., H).

• May be multiple sheets (e.g., H01, H02).

• Shows detail for features and geographic areas.

4. Map Information

The LUCA paper large format map shows some of the same information found on a typical road map, such as streets and roads, water features, and legal boundaries. However, the LUCA map displays this information using symbols unique to the Census Bureau. The map displays the following information:

• Entity boundary.

• Entity name and FIPS Entity Code.

• Census tract boundaries and numbers.

• Census block boundaries and numbers.

• Streets and street names.

• Railroads.

• Water features.

The Map Border

• The key to adjacent areas, if your jurisdiction has multiple map sheets.

• Entity identification information.

• Barcode.

• Scale.

• North arrow.

The Map Legend

• Boundaries.

• Transportation.

• Other Features.

• Landmarks.

• Footnotes and Notes.

See Appendix B for a detailed description of the map legend.

Boundary Improvements

The map products reflect jurisdiction boundary improvements. A boundary improvement may split a census block. In these instances, the split block number contains the root number and a suffix. For example, the root block 1001, split by a boundary improvement, is now 1001A and 1001B. The jurisdiction containing 1001A receives only those addresses located within their jurisdiction. The jurisdiction containing 1001B receives only those addresses located within their jurisdiction.

Figure 16. Boundary Improvements

Map Example

T his example describes some of the symbols used on the Census Bureau Large Format Parent Sheet map.

Figure 17. LUCA Large Format Parent Sheet Paper Map

5. D-2010(SP)—Block to Map Sheet Relationship List

The Block to Map Sheet Relationship List identifies the large format parent map sheet or sheets on which each census block is located. The sort for this product is by census tract number and census block number in ascending order. In the example shown in Figure 18, census block 1000 in census tract 46.00 is located on parent sheets 4 and 6.

Figure 18. LUCA Block to Map Sheet Relationship List

2. The Census Bureau PDF Maps

You need Adobe Reader (or Acrobat Professional) to open and view the LUCA PDF block map. If needed, you can download the free PDF software at <https://acrobat.adobe.com/us/en/acrobat/pdf-reader.html>.

If you selected the digital address list and large format paper/PDF maps, the Title 13 Data Disc contains the Census Bureau’s Title 13 block maps in a folder named “maps.” You need the password sent to you separately from your LUCA materials to open this zipped, encrypted file as described in Section 3.2.1.

All map examples depicting map spots use fictitious information for illustration, instruction, and training purposes only.

1. Opening the PDF Maps

• To keep your work organized, create a new directory or new folder on your hard drive.

• Insert the Title 13 Data Disc.

• Right click on the folder named “maps” and select copy.

Figure 19. “maps” Folder

• Open the new folder and paste the copied “maps” folder.

• Double-click the “maps” folder, the following files appear in the folder:

1. Examples of File Names for Large Format Maps

The following are a few examples of large format map file names using entity types and entity codes:

• LUCA20CS72035.pdf—Large format bundled PDF map for a county (Municipio).

• LUCA20CS72035_BLK2MS.txt—Block to Map Sheet Relationship List for a county (Municipio).

Table 5: Entity Type and Entity Code

<EntType> is Entity Type:	<EntCode> is Entity Code:
CS = Municipio	County = ssccc
	Ss = state code (FIPS)
	Ccc = county code (FIPS)

2. Boundary Improvements

The small format block map products reflect jurisdiction boundary improvements. A boundary improvement may split a census block. For the small format block maps in these instances, the split block number contains the root number and a suffix. For example, the root block 1001, split by a boundary improvement, is now 1001A and 1001B. The jurisdiction containing 1001A receives only those addresses located within their jurisdiction. The jurisdiction containing 1001B receives only those addresses located within their jurisdiction.

Figure 21. Boundary Improvements

4. Reviewing and Updating the Address List and Paper Maps

1. Action Codes

There are five action codes for making updates to the Census Bureau’s Address List. You can add or make updates to residential addresses only. You must include the appropriate Action Code with each address record that you add or update. The Census Bureau will only process address records that contain an Action Code.

A—Add new or missing addresses.

C—Correct this address.

D—Delete this address.

J—Address is not in this jurisdiction.

N—Address is nonresidential.

1. Adding Addresses (The A Action Code)

Use the “A” Action Code to add only residential addresses for your jurisdiction not shown on the Census Bureau’s Address List and to add changed or corrected addresses where the change or correction is not allowed with the “C” Action Code.

There are three city style address types that you may add. Each address type requires that you provide a minimum of address information:

• General address—provide at a minimum a house number, street name, and a ZIP Code.

• Apartment complex address—provide at a minimum an apartment complex/residential name/condominium name, apartment unit, and a ZIP Code.

• Urbanización address—provide at a minimum an urbanización name, address number, and ZIP Code.

To add an address:

• Add/Insert a new line or row in the Census Address List.

• Enter your entity ID in the ENTITYID field. Copy this from your original address list materials.

• Enter an “A” in the ACTION field.

• Enter the census geocode information for state, county, tract, and block in the STATEFP, COUNTYFP, TRACT, and BLOCK fields.

Note: If you choose, you may enter the optional structure latitude and longitude coordinate information in addition to or rather than the STATEFP, COUNTYFP, TRACT, and BLOCK.

• Enter the required address information in the appropriate fields for the new address. Not all fields are applicable to every address.

Note: Optional—If using the small format paper maps, you may add map spot numbers for new address(es) if you know the approximate location of the structure(s). Begin the map spot numbers within the same block with A1, A2, A3 until each added address is recorded and labeled on the paper map. The maximum character length for this field is four characters. You may reuse the same numbering format for each individual block. Ensure that each unique map spot ID recorded and labeled on the paper map is the correct map spot associated with each address added to the Census Address List.

1. Scenario: Adding New Addresses for a New Street to the Census Address List

During your review, you may find addresses missing from the Census Address List located on streets that are partially or entirely missing from the maps. See Figure 47 and Figure 48 for adding new streets to the small format paper maps. Refer to Chapter 5 if you are using shapefiles.

Calle Olisan is a new street with ten newly constructed housing units in census tract 0054.00, census block 2001 in URB Océano. The addresses are missing from the Census Address List and the street is missing from the map.

The address ranges4F⁵ for this street are 101 through 109 on the north side of the street and 100 through 108 on the south side of the street. The address breaks5F⁶ are between 703 and 705 on Calle San Antón and 406 and 408 on Calle Portugués. All ten addresses are used for both mailing and location purposes.

4. Print the address breaks. For this scenario, print the address breaks where Calle Olisan intersects Calle Antón (703-705) and Calle Portuguès (406-408).

2. Adding a New Street and Unique Map Spot Numbers on the Small Format Paper Map

This scenario adds a new street and assigns each housing unit a unique map spot and label to the small format paper map.

Figure 48. Adding a New Street and Unique Map Spot Numbers on the Small Format Paper Map (Training—Fictitious Information)

1. Optional: If you know the approximate location of each housing unit you are adding, you may assign each individual address a unique map spot number, A1, A2, A3, A4, etc.

2. Label each map spot with its associated Map Spot ID that you recorded in the MAPSPOT field in the Census Address List.

2. Scenario: Adding a New Group Quarters to the Census Address List

Although adding a group quarters address is similar to adding a housing unit, group quarters addresses require a group quarters name, facility name, and a GQ flag.

During your review, you find a group quarters containing three individual buildings missing from the Census Address List.

Aristóteles University constructed three new residence halls, Jimenez Hall, Buildings 1, 2, and 3 at 225, 227, and 229 Achilles Drive in ZIP Code 00099. These addresses are for location purposes only.

• Create a new record by starting/inserting a new row in the Census Address List.

3. If there is an alternate street name, print the alternate street name in parentheses.

3. Deleting Addresses (The D Action Code)

Enter a “D” in the Action field to delete an address. Be very careful when using this Action Code. Before deleting an address, ensure that the housing unit or group quarters does not exist, is uninhabitable, is a duplicate address, or needs correcting in a field that is not editable. There are situations where a “C” Action Code is not permissible. In these situations, flag the incorrect record for deletion, “D” Action Code, and add the correct version of the address record using the “A” Action Code.

Duplicate addresses are those incorrectly listed twice on the Census Bureau’s Address List for the same residential address.

You may use the “D” Action Code for city style, non-city style, and ungeocoded addresses.

Do not make corrections to any other fields on the Census Address List for a deleted address. The following is a list of a few examples using the “D” Action Code:

• Deleting addresses that no longer exist.

• Urbanización address- An urbanización type address contains at a minimum an urbanización name, address number, and ZIP Code.

Frequently used non-city style mailing addresses that are included on the Census Bureau’s Address List for LUCA are:

• Physical location description.

• Rural route and box number.

• Highway contract route and box number, which may include KMHM information.

Non-city style addresses often do not follow any numeric sequence and may not be associated with the name of the street or highway on which they are located. For this reason, the Census Bureau uses different methods to compile the list of addresses for inclusion into the address list, such as a physical location description (BRICK HSE w/ATTACHED GARAGE ON RIGHT), structure points (geographic coordinates), and census geographic codes (state code, county code, census tract number, census block number).

Rural routes and highway contract routes are mailbox delivery routes served by rural carriers to deliver and collect mail from roadside mailboxes. In addition to the route and box numbers, these addresses may also include a complete address number, complete street name, and location description, or any combination used for emergency location services, such as police, fire, and rescue (E-911 addresses). In some instances, the complete address number and box number are identical. In other instances, the rural or highway contract route and box number and the complete address number are different.

Since PO Box numbers and general delivery addresses are mailing addresses only and not associated with a housing unit or housing unit location, the Census Bureau cannot accept them through the LUCA operation.

1. Adding Non-city Style Addresses to the Census Address List

The most common non-city style addresses on the Census Bureau’s Address List are:

• Physical location description and identifying map spot.

• Rural route and highway contract route and box numbers.

In addition to Rural Route, Highway Contract, General Delivery, or PO Box, for non-city style addresses, please provide whatever address elements are known for the physical location of the address, including street name, kilometer/hectometer, area name(s) (i.e. Barrio, Sector, Barriada, Parcela, Communidad).

The following instructions provide a few examples of how to add non-city style addresses missing from the Census Address List.

1. Scenario: Adding Physical Location Description Addresses

The area north of Calle Candela includes three housing units. The housing units are numbered (1 through 3), but located on an unnamed road. The ZIP Code for the area is 00099. The physical location descriptions are missing from the Census Address List and their identifying map spots are missing from the map. These housing units do not have city style addresses.

Note: In addition to the required state and county codes, and census tract and block codes, you must provide a well-defined description of the housing unit or group quarters location and either identify the approximate location on the appropriate small format block map or the latitude and longitude coordinates for participants with shapefiles. This is the information the enumerator uses to conduct the census at this address.

1. You must provide the approximate location of each address you are adding. You may assign each individual address a unique map spot number, A1, A2, A3, etc.

2. Label each map spot with its associated unique map spot number that you recorded in the MAPSPOT field on the Census Address List beginning with A1, A2, A3, etc.

2. Correcting Non-city Style Addresses

The following corrections to non-city style addresses are the same as city style addresses described in Section 4.1.2.

Enter a “C” in the ACTION field for the following situations:

• Incorrect state code.

• Incorrect county code.

• Incorrect census tract number.

• Incorrect census block number.

• Incorrect street name (including street directional and street type information).

• Incorrect geographic area name (e.g., Barrio, Barriada, Sector, Parcel, Comunidad, etc.)

• Incorrect KMHM.

• Incorrect map spot number.

• Incorrect structure latitude.

• Incorrect structure longitude.

3. Deleting Non-city Style Addresses

Identical to the city style address delete action, enter a “D” in the ACTION field to delete an address. Be very careful when using this Action Code. Before deleting an address, ensure that the housing unit or group quarters does not exist, is uninhabitable, is a duplicate address, or needs corrected in a field that is not editable. Do not make corrections to any other fields on the Census Address List for an address record marked for deletion. The following is a list of a few examples using the “D” Action Code:

• Deleting an address that no longer exists, is uninhabitable, or is a duplicate.

• Deleting a street or addresses along a street that no longer exists.

• Incorrect house number.

• Incorrect apartment or unit number.

• Deleting an incorrect Non-city Style Mail Delivery Address (RR# or HCR#) and adding the correct address.

• Deleting an address for a single housing unit converted to a multiunit structure on the Census Address List and adding multiunit addresses.

• Deleting addresses for a multiunit structure converted to a single housing unit and adding the single housing unit address.

• Deleting a single housing unit address converted to a group quarters and adding the group quarters address.

• Deleting a group quarters address converted to a single housing unit and adding the single housing unit address.

• Deleting addresses with incorrect physical location description and adding a record for the corrected location description and map spot.

1. Updating a Physical Location Description and Map Spot Address

To update a physical location description and map spot address mark the address for deletion and add the updated address to the Census Address List. In addition to the required state and county codes, and census tract and block codes, provide a well-defined description of the housing unit location (up to 100 characters, do not use commas). If the location is the same, reenter the map spot number to the updated address. This is the information the enumerator uses to conduct the census at this address.

1. Scenario: Deleting a Physical Location Description Address in the Census Address List

Physical location descriptions may change over time for a number of reasons. For instance, structures may be painted different colors, driveway access or surfaces may change, or environmental or landscapes may change.

The area north of Calle Candela developed over the last several years. The tan trailer identified by map spot number 1, no longer exists. A brown house with beige trim and an attached two-car garage replaced the tan trailer.

• Enter the secondary geographic area information in the AREA 2 field. Include the appropriate type Sector (SEC), Barriada (BDA), Comunidad (COM) or Parcela (PARC) with the geographic area. For example, SEC Chris or PARC James.

• Enter any kilometer/hectometer information in the KMHM field.

• Enter any location and physical description characteristics (up to 100 characters, do not use commas) not captured in the previous fields in the LOCATION DESCRIPTION field. For example, enter “Area north Calle Candela. Brown house with beige trim and an attached two-car garage” in the LOCATION DESCRIPTION field.

• Enter any rural or highway contract route and box numbers in the NONCITYSTYLE ADDRESS field, if applicable. If present must include a ZIP Code in the NONCITYSTYLE ZIP field.

• Enter 5-digit USPS ZIP Code for above rural or highway contract route and box number information in the NONCITYSTYLE ZIP field, if applicable.

• Enter the address use, if known, in the USE field.

M—Mailing purposes.

L—Location purposes, including emergency services, or

B—Both mailing and location purposes.

• Enter the original map spot number in the MAPSPOT field, if the location is still the same. If the location has changed, assign a new map spot ID and make the appropriate map update.

• Enter the structure latitude in the LAT field. This would be same as the deleted address. If the location has changed, enter the new latitude in the LAT field.

• Enter the structure longitude in the LONG field. This would be same as the deleted address. If the location has changed, enter the new latitude in the LONG field.

Refer to Section 4.1.3 for additional examples of using the “D” Action Code.

3. Ungeocoded Addresses—States and Counties Only

The Census Bureau’s Address List for state and county participants may contain ungeocoded addresses that are missing census tract and census block codes. Ungeocoded addresses are located at the end of the address list file. You may use the “C,” “D,” “N,” and “J” Action Codes to include geocodes (census tract and census block) for addresses (C), delete (D) addresses, identify nonresidential (N) addresses, and to identify addresses not in your jurisdiction (J). When entering the “D,” “N,” and “J” Action Codes make no other entries.

The following scenario describes how to include geocodes for ungeocoded addresses using the “C” Action Code and identify their location on the map.

1. Scenario: Including Geocodes for Ungeocoded Addresses on the Census Address List

To geocode ungeocoded addresses, enter a “C” in the ACTION field and provide the geocode information for the census tract and census block. If you choose, you may enter the optional structure latitude and longitude coordinate information in addition to or

The Census Address List for Winter County contains several new addresses that are missing geocodes for the census tract and census block.

• Enter a “C” in the ACTION field.

• Enter the required information in the appropriate fields to geocode the addresses, including census TRACT and BLOCK.

• Optional: If you know the approximate location of each address, assign a unique map spot number in the MAPSPOT field.

1. Identifying Ungeocoded Addresses with Unique Map Spot Numbers on the Small Format Block Map

This scenario illustrates the ungeocoded addresses identified with their unique map spot numbers on the small format block map.

Figure 59. Identifying Ungeocoded Address with Unique Map Spot Numbers on the Small Format Paper Map (Training—Fictitious Information)

1. If you know the approximate location of each address you are geocoding, you may assign each individual address a unique map spot number, A1, A2, A3, etc.

2. Label each map spot with its associated unique map spot number that you recorded in the MAPSPOT field on the Census Address List beginning with A1, A2, A3, etc.

If you need to add a new street on the map, follow the instructions in Section 4.1.1.1.

4. Transitory Location Addresses

Transitory Locations (TLs) are sites that contain movable or mobile housing, or portable housing units, including boats, motorized recreational vehicles (RVs), tents, trailers that are pulled by cars or trucks, or any other type of portable housing used as a living quarters.

The Enumeration of Transitory Locations (ETL) is a census operation designed to provide coverage for enumeration for locations where people live in non-traditional housing that is transient or movable in nature. The types of TLs that are included in the ETL include:

• RV parks.

• Marinas.

• Campgrounds.

Although you may find TLs that are unnamed on your address list, a few examples of named TL addresses include:

• Mermaid’s Marina, 23 South Main Street, 99997.

• The Royal Winter Campground, 76 Alexander Blvd, 99997.

Individual addresses at TLs are identified as Transitory Unit (TU) addresses. The MAF may include TU addresses as housing units (HUs). TU addresses identified as HUs pass the address filter as residential housing units and therefore may be included on your Census Address List. Individual TU addresses include:

• Pads.

• Sites.

• Slips.

• Units.

• Rooms.

Examples of TU addresses include:

• Mermaid’s Marina, Slip 63, 23 South Main Street, 99997.

• The Royal Winter Campground, Site 234, 76 Alexander Blvd, 99997.

The Census Bureau will not accept individual TU addresses for pads, sites, slips, units, or rooms for the LUCA operation. TU addresses are identified and documented during the ETL.

You may delete an existing TU address if you are certain that the address is a TU or does not exist. Do not make corrections to any other fields on the Census Address List for a deleted address.

• Enter a “D” in the Action field for the address(es) that need deletion.

No other action is required.

Updating Transitory Location Addresses

There are several updates you may make to TL addresses including:

• Adding missing TL addresses. These include main office addresses only, located at the TL.

• Updating incorrect TL addresses by deleting and adding the correct TL address.

• Deleting TL addresses that no longer exist or are uninhabitable.

1. Scenario: Adding a Transitory Location Address

A new marina, Winters Marina, opened at 211 Jeffras Drive.

• Create a new record by starting/inserting a new row in the Census Address List.

• Enter the entity ID code in the ENTITYID field. Copy this from your original address list materials.

• Enter an “A” in the ACTION field.

• Enter the STATEFP, COUNTYFP, TRACT, and BLOCK for the address.

Note: If you choose, you may enter the optional structure latitude and longitude coordinate information in addition to or rather than the STATEFP, COUNTYFP, TRACT, and BLOCK.

• Enter the correct address house number in the HOUSE NUMBER field.

• Enter the street name in the StreetName field.

• Enter the mailing ZIP Code in the ZIP field.

• Enter the TL name in the GQ NAME field.

• Enter “TL” in the LOCATION DESCRIPTION field.

• If you know the approximate location provide a unique map spot number (e.g., A1) in the MapSpot field. The map spot number in the Census Address List must correspond to the building’s location if you are using the small format paper map. Refer to Figure 50. Identifying a New Multiunit Structure on the Small Format Paper Map to add a map spot on the small format paper map.

• Enter the address use, if known, in the USE field:

M—Mailing purposes.

L—Location purposes, including emergency services, or

B—Both mailing and location purposes.

• Enter the structure latitude in the LAT field, if known.

• Enter the structure longitude in the LONG field, if known.

2. Scenario: Correcting a Transitory Location Address

To correct an incorrect TL address, you must first delete the incorrect address using the “D” Action Code, then add the entire corrected address using the “A” Action Code.

During your address review, you notice that the main office address for John’s Campground listed on the Census Address List is now Sleepy’s Campground. This campground continues to rent spaces for transients.

• Enter a “D” in the ACTION field for the address that needs correction.

Add the correct address to the Census Address List:

• Create a new record by starting/inserting a new row in the Census Address List.

• Copy the original address and paste it into the new row.

• Enter an “A” in the ACTION field.

• Enter the TL name in the GQ NAME field.

• Enter “TL” in the LOCATION DESCRIPTION field.

• Enter a unique map spot number (e.g., A1) in the MAPSPOT field if the map spot number is missing from the original address. The map spot number in the Census Address List must correspond to the building’s location if you are using the small format paper map. Refer to Figure 49 to add a map spot on the small format paper map.

• Enter the address use, if known, in the USE field:

M—Mailing purposes.

L—Location purposes, including emergency services, or

B—Both mailing and location purposes.

3. Scenario: Deleting a Transitory Location Address

The main office and the campground located at 101 Pampas Place no longer exists.

• Enter a “D” in the Action field for the address(es) that needs deletion.

No other action is required.

5. Saving the Census Address List File

Save your work often to avoid possible loss of your edits. In addition to saving the file often, you should back up your work each week. In the event of hardware failures and/or software corruption, this process ensures that, at most, a week’s worth of work is lost.

When you have finished updating the digital address list file:

• Re-sort the entire Census Address List by the “ACTION” field grouping all records with an action code together.

• Save only those records that have an entry in the “ACTION” field.

• Name the file containing the updated address list with Action Codes only: luca20_<EntityID>_changes_addresses.xxx where xxx is the file extension type such as the comma delimited text extension (.csv or .txt) or Excel (.xls). The <EntityID> is your entity identification code found on your LUCA materials.

• Make a copy of your edited files to keep for your records and to use during the Feedback phase of LUCA.

Note: Use caution while re-sorting and ensure the selection of all fields and rows within the Census Address List prior to sorting. Not ensuring all fields and rows are selected will scramble the contents of the Census Address List and may cause irreparable damage.

• All digital copies of the Census Address List, as well as paper copies, with or without changes, are Title 13 address information. Keep all copies in a secure location according to the Confidentiality and Security Guidelines.

• See Chapter 7 for preparing and submitting your Title 13 materials to the Census Bureau.

5. TIGER Partnership Shapefiles

As part of the LUCA registration process, the Census Bureau offered LUCA participants the opportunity to choose shapefiles as their product preference map format. The Census Bureau provides county-based Environmental Systems Research Institute7F⁸ (Esri) shapefiles. The shapefiles, created from the MAF/TIGER system, allow participants to submit map feature updates electronically. Participants that submit shapefiles with feature updates must follow Census Bureau instructions discussed in this chapter.

1. Shapefile Background

In order to submit digital feature information, you must have a GIS capable of importing Esri shapefiles, editing the features, and exporting layers back into Esri shapefile format. Subsequent sections within this chapter provide details on these three steps.

The Census Bureau’s TIGER Partnership shapefiles contain numerous sets of shapefiles, but do not contain structure point (map spots) shapefiles. Using GIS, LUCA participants may utilize the “LAT” and “LONG” data from the digital address list to generate structure points. To geocode addresses to the census blocks, the Census Bureau provides a 2010 tabulation block shapefile (tabblock2010). All linear features in the Census Bureau’s MAF/TIGER system are contained in the “edges” shapefile. Participants use the “edges” shapefile to add and delete features as well as change feature attribution. This chapter provides examples of edits to the edges shapefile.

1. Shapefile Setup

The TIGER Partnership shapefiles provided by the Census Bureau are in the following un-projected geographic-based coordinate system:

• GCS_NAD83

• Angular Unit: Degree (0.017453292519943299)

• Prime Meridian: Greenwich (0.000000000000000000)

• Datum: D_North_American_1983

• Spheroid: GRS_1980

• Semi-major Axis: 6378137.000000000000000000

• Semi-minor Axis: 6356752.31414035610000000

• Inverse Flattening: 298.257222101000020000

If you selected the digital address list and digital maps, disc 2 of 2 contains the
non-Title 13 Address Count List and the TIGER Partnership shapefiles in a folder named “shape.” Upon completion of the initial setup of files by launching the executable file to place the contents of the discs in specific folder you created, open the file and ensure the file contains the shapefiles for your entity. If your entity spans more than one county or state, save the shapefile for each state and county to the specific folder you created during the launching of the executable file. If data is missing or you encounter an error with the files, please immediately contact the Geographic Partnership Support Desk toll-free at 1-844-344-0169 or send an email to geo.2020.luca@census.gov.

Please feel free to re-project these shapefiles into your local coordinate system projection; however, the Census Bureau requests you convert the submission back to GCS NAD83 prior to submission. Most GIS software packages contain projection wizards, or something similar, allowing the user to transform file coordinate systems and projections. For example, if your office uses ArcGIS to update files, please activate and utilize ArcGIS’s “Projection Utility Wizard” extension.

TIGER Partnership shapefiles contain defined projection information in the *.PRJ file. Since ArcGIS accesses the *.PRJ file for projection information, there is no need to define these parameters before changing the file coordinate system.

2. Editing Features in the Edges Shapefile

After performing the set up guidelines and reviewing the Census Address List as well as the features in the edges shapefile, if you determine that the Census Bureau needs to add or delete features or modify attribution of features, you must submit your modifications in a separate shapefile.

Note: Although the primary purpose of LUCA is to update the Census Bureau’s Address List, it may be necessary to update spatial features that correspond to address updates. Due to the limited time to provide LUCA updates, participants should focus on providing road updates that impact addresses such as new roads.

• To add a new or missing feature, digitize or copy the feature into the edges shapefile and update the MTFCC, FULLNAME, and CHG_TYPE attribution fields.

• To move or correct the shape of a feature, first mark the feature for deletion by updating the CHG_TYPE field then add the feature and necessary attribution updates (MTFCC, FULLNAME, and CHG_TYPE) in its proper location. Movement and correction of the shape of a feature is a delete/add scenario.

• To mark a feature, or part of a feature, for deletion, update the CHG_TYPE attribution field for the section of edge to delete, but do not delete the actual feature from the shapefile.

In each of these instances, use the appropriate change type code located in the coding scheme as shown in Table 6 to identify the type of feature modification in the CHG_TYPE field of the edges shapefile. Specific examples of these updates in Section 5.1.3 Change Type Codes and Example of Edges Shapefile Corrections.

Note: The Census Bureau encourages the use of imagery during your review to assist with the proper spatial placement of features.

Table 6 contains a portion of the edges shapefile data dictionary that define important attribute information contained in the edges shapefile. Refer to Appendix L, Shapefile Layouts, for a complete layout.

Table 6: Edges Shapefile Data Dictionary

Field	Length	Type	Description
TLID	10	Integer	Permanent edge ID
MTFCC	5	String	MAF/TIGER Feature Class Code
FULLNAME	120	String	Feature name
CHNG_TYPE	4	String	Type of linear feature update

• TLID is the unique TIGER/Line^® ID for the feature segment and is not editable. Leave this field blank if adding a new feature.

• The MAF/TIGER Feature Class Code or MTFCC identifies the most noticeable characteristic of a feature. This field is required when adding new features. Participants can modify this field if the current MTFCC is incorrect. The MTFCC is a 5-character code. The first character is a letter describing the feature class. For example, S1400 identifies streets and roads. Refer to Appendix K for the MAF/TIGER Feature Classification table.

• FULLNAME is the feature name. This field is editable and is required when adding new or missing features.

• CHNG_TYPE identifies the type of feature modification. This field is required in order to identify all of the edges with proposed changes. See Table 7 for the change type codes and their descriptions.

3. Change Type Codes and Example of Edges Shapefile Corrections

This section discusses the three change type codes and provides examples of each. Each update to the edges shapefile must contain one of the three “change type” codes listed in Table 7. Record the change type code within the CHNG_TYPE field in the edges shapefile attribute table for each feature in which an update occurs.

Table 7: Change Type Codes for Feature Corrections

Code	Description
AL	Add Line
CA	Change Attribute
DL	Delete Line

ADD LINE

• Code—AL

• Used to flag a new road feature added to the edges shapefile.

• Provide the features name in the FULLNAME field and appropriated feature class code in the MTFCC field.

CHANGE ATTRIBUTE

Change Name

• Code—CA

• Used to flag a feature to denote a name change.

• Provide the feature’s new or corrected name in the FULLNAME field.

Change MTFCC

• Code—CA

• Used to flag a feature to denote a change to the feature class code (e.g., a local road, S1400, mistakenly coded as a highway, S1200)

DELETE LINE

• Code—DL

• Used to flag a feature for deletion.

• Do not actually delete the feature from the edges shapefile and make no other changes to the feature or attribution.

4. Examples

The following are examples of change type codes for feature additions, deletions, and attribute corrections.

1. Scenario: Adding a Feature to the Edges Layer

Crystal Ave is a new street. It is missing from the edges shapefile and needs to be added.

• Start an Editing session on the edges shapefile.

• Open the “Create Features” window in the Editor tool, which you can find under Editing Windows.

Figure 60. Create Features

• Click the “Line” under Construction Tools. You will now be able to draw your road.

Figure 61. Line Tool

• Digitize the missing street into the edges shapefile. The Census Bureau strongly recommends using imagery (from ArcGIS or local sources) to ensure the accuracy of the road placement and digitizing at an appropriate scale (1:2,400 for instance).

• To digitize (in ArcGIS), left click with your mouse at the starting point (node) and draw until the road is complete. Once finished, double left click the mouse to complete the creation of a new line in the attribute table.

Figure 62. Digitizing a New/Missing Street

In the edges shapefile attribute table:

• For the newly created street, enter the appropriate feature class code in the MTFCC field. In this example, S1400 is the correct choice.

• Enter Crystal Ave in the FULLNAME field.

• Enter AL in the CHNG_TYPE field.

• Leave all other fields blank.

• Click “Save Edits”, then “Stop Editing” in the Editing Toolbar.

• The map and attribute table should resemble the example below:

Figure 63. Map and Attribute Table for Adding a New/Missing Street

Although the street name in the examples may differ, refer to Section 4.1.1.1, Scenario: Adding New Addresses for a New Street to the Census Address List for instructions on the corresponding address list updates.

2. Scenario: Correcting a Feature Name

The Census Bureau’s address list and shapefile incorrectly identifies a street as Mound Rd rather than Mountain St, the correct street name.

• Start an editing session on the edges shapefile.

• Select all segments of Mound Rd in the edges shapefile.

In the edges shapefile attribute table:

• Edit the FULLNAME field, in this case correcting it from Mound Rd to Mountain St.

• Enter CA in the CHNG_TYPE field.

• Save your edits.

• The map and attribute table should resemble the example below:

Figure 64. Map and Attribute Table for Correcting a Street Name

Although the street name in the examples may differ, refer to Section 4.1.2.3, Scenario: Correcting an Incorrect Street Name, Urbanización, Condominium, Complex Descriptor, Area Name, and KMHM in the Census Address List for instructions on the corresponding address list updates.

3. Scenario: Changing the MTFCC of an Existing Feature

A local road, Oak St, is miscoded with a highway feature class code.

• Start an editing session on the edges shapefile.

• Select all segments of Oak St in the edges shapefile.

In the edges shapefile attribute table:

• Change the code in the MTFCC field from S1200 to S1400.

• Enter CA in the CHNG_TYPE field.

4. Scenario: Deleting a feature

The Census Bureau’s address list and edges shapefile contain Donahue St; however, local sources and knowledge confirm the road and houses were never constructed.

• Start an editing session on the edges shapefile.

• Select the segment of Donahue St in the edges shapefile that no longer exists.

In the edges shapefile attribute table:

• Enter DL in the CHNG_TYPE field for the selected segment of Donahue St that no longer exists.

• Save your edits.

• The attribute table should resemble the image below:

Figure 66. Attribute Table for Deleting a Road Feature

Although the street name in the examples may differ, refer to Section 4.1.3.1, Scenario: Deleting Addresses that No Longer Exist on a Section of a Street in the Census Address List and Section 4.1.3.2, Scenario: Deleting Addresses that No Longer Exist on a Street that No Longer Exists in the Census Address List for instructions on the corresponding address list updates.

5. Scenario: Correcting the Location of a Street Located in an Incorrect Census Block

The Address List and edges shapefile incorrectly show Court St located north of Brass Alley. According to local sources, Court St is located south of Brass Alley. Add Court St in the correct location in the edges layer and mark the incorrect Court St segment for deletion.

Figure 67. Incorrect Location of a Street

• Start an editing session on the edges shapefile.

• Digitize Court St into the correct location.

• Ensure the feature is spatially accurate by utilizing imagery as a reference.

In the edges shapefile attribute table:

For the new, correct feature:

• Enter the appropriate MTFCC code for the new street. In this example, S1400 is the correct choice.

• Enter Court St in the FULLNAME field.

• Enter AL in the CHNG_TYPE field.

• Leave all other fields blank.

For the incorrect feature:

• Enter DL in the CHNG_TYPE field to flag the incorrect segment(s) of Court St for deletion.

• Save your edits.

• The map and attribute table should resemble the example below. The line for Court St marked for deletion is above Brass Alley and the newly added line for Court St is below Brass Alley. Both features are visible in the map and attribute table. The CHNG_TYPE field in the attribute table for the incorrect feature is marked with a “DL”, while the correct feature has an “AL.”

Figure 68. Map and Attribute Table for Correcting the Location of a Street

Although the street name in the examples may differ, refer to Section 5.1.4.5, Scenario: Correcting the Location of a Street Located in an Incorrect Census Block for instructions on the corresponding address list updates.

2. Preparing Your Edited Shapefile for Submission

Upon completion of your LUCA review and updates, follow the instructions in this section for preparing your edited shapefile for submission to the Census Bureau. Additional instructions for compiling your entire submission are included in Chapter 7.

• Ensure that your edges shapefile has all the desired additions and edits.

• Select all of the features with a value in the CHNG_TYPE field of the edges shapefile in order to export the selected features and their attributes into a new shapefile.

• Right click on the edges shapefile and select “Data”, then “Export Data”, as shown in the image below.

Figure 70. Export Data Selection

Figure 71. Export Data

• Ensure “Selected Features” remains set in the “Export” section of the “Export Data” window.

• Name the new shapefile “luca20_<EntityID>_In_changes.shp” where the EntityID is the entity identification code found on your LUCA materials (starts with two letters followed by a series of numbers).

• Save the shapefile to an easily accessible location on your computer.

• Click “OK” to export the shapefile.

The newly exported LUCA submission shapefile should resemble the map and attribute table below, only containing the edited features.

Figure 72. Edited Road Features for Submission

6. Generating Structure Points with ArcGIS

1. Using ArcGIS to Generate Structure Points from the Digital Address List

The U.S. Census Bureau will supply participants choosing the Digital Address List product preference with a .csv file containing all of the known addresses for a given entity. Many of these addresses will have latitude and longitude values in the corresponding fields (see Error! Reference source not found. in Chapter 2).

Note: Title 13 protects the Census Bureau’s address list and used only for reference during your LUCA review. You must destroy any shapefiles created based on the Census Bureau’s address list must after the LUCA operation is complete.

Follow the steps below to import the address list into ArcGIS to create points to compare the Census Bureau’s addresses with your own address points.

• In ArcGIS, right click “Layers” in the Table of Contents and select “Add Data.”

Figure 73. Selecting Layers in ArcGIS

• Navigate to the folder where you address list (in .csv format) is located.

• Add to your MXD by clicking “Add”.

Figure 74. Add Address Data

• In ArcGIS, right click the .csv file in the Table of Contents.

• Select “Display XY Data.”

Figure 75. Display XY Data

• Use the drop down menus for the X and Y Fields to select the correct longitude and latitude fields in your address list, where the X field represents the longitude and the Y field represents the latitude.

• Click “Edit” button to change the Coordinate System to NAD (North American Datum) 1983, if not shown in the Description section of the window.

Figure 76. X and Y Fields

• Search for “GCS_North_American_1983” and select “NAD 1983.” Choose the “Geographic Coordinate Systems” folder, then the “North America” folder. Next select “NAD 1983.” Click “OK” to select the coordinate system.

Figure 77. Selecting NAD 1983

• The “Display XY” Data screen displays again. Once you confirm that everything is set up properly, click “OK” on the “Display XY Data” screen to complete the action and dismiss the window.

Figure 78. Display XY Data Screen

After the “Display XY Data” window closes, the warning message shown below appears indicating the lack of the Object-ID field in the newly created file. In order to link the spatial points to the attributes, export the newly created point layer to a new shapefile in order to select, query, or perform edits on the shapefile.

Figure 79. Warning Message

• After selecting “OK” to dismiss the “Table Does Not Have Object-ID Field” warning message, ArcGIS generates an “Events” shapefile of the address points on your map corresponding to the longitude and latitude of each address in the address list that contains values in those fields. Please note, not all records in the Census Address List contain coordinate information.

• If the address points do not appear correctly located for your jurisdiction, then prior to performing the next steps, check to see if the LAT and LONG fields are correct. The X is the LONG and the Y is the LAT. Perform the “Display XY Data” step again to correct the points if they do not display properly.

• After the XY data “Events” shapefile loads into your MXD, right click the file name, select “Data,” then select “Export Data.” Next click “OK.”

Figure 80. “Events” Shapefile

• In the “Export Data” window, you can change the directory location and file name for the soon-to-be generated shapefile by choosing the folder icon in the “Output feature class” section and clicking “Save.”

• Once the “Output feature class” is correct, click “OK.”

Figure 81. Export Data Confirmation

• An ArcGIS window asks whether you “want to add the exported data to the map as a layer.” Select “Yes.” The data should now load into the MXD.

• Delete the “Events” shapefile from the MXD Table of Contents.

• Performing the additional “Export Data” step links the attribution to the spatial elements of the file so proper queries and selections can occur. The blue highlighted row in the attribute table now highlights the corresponding map spot on the map.

Figure 82. Corresponding Address and Map Spot Highlighted

You can follow the steps above for loading your own address point spreadsheet data to compare the two datasets spatially and determine if there are areas where the Census Bureau is missing map spots; and therefore, may be missing residential addresses.

7. Submitting Your Updated Materials

After completing your review and update of the LUCA materials, return only those materials with updates to the National Processing Center at the address shown in Figure 83. Please include or submit the Inventory Form for the Return/Submission of Materials [D-2011(SP)] with your updated LUCA materials. Follow the procedures for shipping Title 13 materials discussed in this chapter and referenced in Appendix A, Confidentiality and Security Guidelines [D-2004(SP)].

After your review, if you determined that the Census Address List is correct and you have no address updates, complete form D-2079(SP) included with your LUCA materials and return it using the enclosed postage-paid, preaddressed envelope. If you do not want to receive LUCA Feedback materials, you must destroy or return all Title 13 address and map materials according to the procedures outlined in the Confidentiality and Security Guidelines in
Appendix A.

Methods for Submissions

There are two methods for submitting your updated LUCA materials:

1. Secure Web Incoming Module (SWIM):

• You may submit your zipped digital address list updates and/or shapefiles through SWIM, the official web portal for uploading partnership materials to the Census Bureau. See Section 7.6 for specific instructions on using SWIM.

2. Shipping:

• You may ship your zipped digital address list updates, shapefile updates, and/or updated, printed PDF paper maps to the Census Bureau. Please follow the procedures outlined in the following sections to ensure the protection of Title 13 materials.

If any issues arise with your LUCA submission, the Census Bureau will attempt to contact you to resolve or clarify the issues. Unless there is clarification prior to the LUCA deadline, the Census Bureau will not incorporate your updates into the MAF/TIGER database. Your updates are temporary until the verification operation provide confirmation.

1. Preparing the Address List for Submission

• Navigate to the directory where you saved your address changes file as explained in Chapter 4, Section 4.4.

Note: The Census Bureau cannot accept files submitted via email, nor can we retrieve files from a FTP site. Participants must create a CD/DVD for shipment to the Census Bureau or must use the SWIM to post the files to ensure a secure transfer of information.

• Zip the luca20_<EntityID>_changes_addresses.xxx (where xxx is the file extension type such as the comma delimited text extension (.csv or .txt) or Excel (.xls)) and name it luca20_<EntityID>_changes_addresses_return.zip.

• Password protect this file as part of the zip process using the case sensitive password provided to you for your original materials. If you have misplaced the password, contact the Geographic Partnership Support Desk toll free at
  1-844-344-0169 for assistance. The Census Bureau cannot email passwords.

• Save the file to a CD or DVD.

2. Sorting the Paper Maps for Submission

To return the printed small format block maps with updates to the Census Bureau:

• Separate the map sheets with updates from those without updates.

• Make a copy of all map sheets containing updates to keep for your records to use during the Feedback phase of LUCA scheduled to occur in August/September 2019.

• Return only those map sheets containing updates.

Note: All address list copies and maps with map spots are Title 13, U.S.C. address information. Keep all copies in a secure location. Follow the confidentiality and security guidelines for both paper and digital security.

3. Preparing the Shapefiles for Submission

• Navigate to the directory where you saved your shapefile changes file.

Zip the luca20_<EntityID>_In_changes.shp and all associated metadata and component file (.cpg,.dbf, .prj, .sbx, .shx, .shp, etc.) and name it: luca20_<EntityID>_ln_changes_return.zip. There is no need to password protect this file because it does not contain any Title 13 information.

Note: Participants using Esri software should utilize ArcCatalog to ensure the necessary file components are bundled in the zip file appropriately. Participants using another GIS software must ensure all of the components are included in the zip file for accurate processing once received at the Census Bureau

• You may save the file to the same CD/DVD as your address list if you are shipping your submission.

4. Completing the D-2011(SP) Inventory Form for the Return/Submission of LUCA Updated Materials

If you are shipping your updated LUCA materials, please complete the D-2011(SP) Inventory Form for the Return/Submission Materials you received in your LUCA materials package and include it with your returned materials. A copy of the form is included in Appendix H and is available for download on the LUCA Web site at <http://www.census.gov/geo/partnerships/luca.html>.

If you are submitting your updated Census Address List and/or shapefiles through SWIM, the fillable the D-2011(SP) Inventory Form for the Return/Submission of Materials PDF form is included on your digital file discs as LUCA20_inventory_pr.pdf. When you open this file:

• Complete the Entity ID and Government Name sections.

8. Next Steps

Congratulations on the completion of your 2020 LUCA review. While this is a major first step, this does not conclude your LUCA participation, unless you do not wish to receive feedback. Once the Census Bureau receives your submission, we will process your files for validation. After validation concludes in, the Census Bureau prepares the LUCA feedback materials for shipment to you in the summer of 2019.

If you agree with the Census Bureau’s feedback materials, then your LUCA participation ends. The Census Bureau begins outreach to close out the LUCA operation and confirm the destruction or return of all Title 13 materials. The Census Bureau must receive a signed Destruction or Return of Title 13 Materials Form [D-2012(SP)] which confirms your destruction (preferred method) or return of the Title 13 materials as required by law. This form was included with your original LUCA materials but is also included in this respondent guide as Appendix I. The Confidentiality and Security Guidelines [D-2004(SP)] in Appendix A outlines the process for both the destruction (preferred method) and the return of Title 13 materials.

If you disagree with the results of the Census Bureau’s validation of your submission, you have 30 days from the receipt of the feedback materials to notify the LUCA Appeals Office, managed by the Office of Management and Budget (OMB), of your disagreement. They will work with you and the Census Bureau to resolve all disagreements. After a determination to accept or reject disputed addresses by the Appeals Office, the Census Bureau includes addresses accepted by the Appeals Office into the 2020 Census enumeration universe. Once the appeals process concludes, you must destroy or return to the Census Bureau your Title 13 materials and submit a signed Destruction or Return of Title 13 Materials Form [D-2012(SP)] as required by law. Filing an appeal is optional and is not a requirement of the LUCA operation.

13. Glossary

Address breaks—Address breaks identify the city style addresses on each side of a boundary or at an intersection of street with another street or another feature.

Address Count List—Identifies the number of housing unit addresses and group quarters addresses on the Census Bureau’s Address List for each census block within a jurisdiction.

Address range—The lowest and highest address numbers used to identify structures along each side of a street segment that has city style addresses. Usually one side of the street has even address numbers and the other side has odd address numbers.

Block to Map Sheet Relationship List—A list identifying census block numbers and the Census Bureau large format map(s) on which each block is located.

Boundary—A line, on a map, either invisible or coincident with a visible feature that identifies the extent of a geographic entity, such as a census tract, city, county, or state. A boundary marks the limits of an area.

Census Address List—The Census Bureau’s Address List, extracted from the Master Address File (MAF) for review and update during 2020 LUCA, contains all the residential addresses (city style and non-city style) known to the Census Bureau for your government. It also contains census geographic codes (state, county, census tract, census block) that indicate the location of each address. Many addresses also contain latitude and longitude coordinates depicting the address location.

Census block—A census block is an area bounded by visible and/or invisible features shown on Census Bureau maps. A census block is the smallest geographic area created by the Census Bureau for which it collects and tabulates decennial census data. Census blocks are numbered within census tracts and are uniquely numbered within census tracts.

Census block number—Census block numbers are a 4-digit number plus up to two alpha character suffix, if applicable, e.g. 3001A or 2002AA. Suffixes, boundary changes as well as added features within the given block that split the original block.

Census Bureau—An agency within the U.S. Department of Commerce. The U.S. Census Bureau is the country's preeminent statistical collection and dissemination agency. It publishes a wide variety of statistical data about people and the economy of the nation. The Census Bureau conducts approximately 200 annual surveys and conducts the decennial census of the United States population.

Census Bureau map—Any map produced by the Census Bureau. A Census Bureau map displays geographic entities used in a Census Bureau sponsored census or survey for which the Census Bureau tabulates data.

Census tract—A small, relatively permanent statistical subdivision of a county or statistically equivalent entity delineated for data presentation. Designed to be relatively homogeneous units with respect to population characteristics, economic status, and living conditions at the time of establishment, census tracts generally contain between 1,000 and 8,000 people, with an optimum size of 4,000 people. Delineated with the intention of being stable over many decades, census tract boundaries generally follow relatively permanent visible features. However, they may follow governmental unit boundaries and other invisible features in some instances; the boundary of a state or county (or statistically equivalent entity) is always a census tract boundary.

Census tract number—Unique numbers to identify census tracts within a county or statistically equivalent entity. Census tract numbers are a 4-digit number followed by a decimal point and a 2-digit number for suffixed tracts, e.g., 1234.01. For census tracts without a suffix, the number will contain a period with zero fill, e.g., 4567.00.

City style address—The Census Bureau’s definition of a city style address is an address consisting of a house number and street or road name. For example, 201 Main Street is a city style address. The address may or may not be used for the delivery of mail and may include apartment numbers/designations or similar identifiers.

Confidentiality—The guarantee made by law (Title 13, United States Code) to individuals who provide information about themselves or their business to the Census Bureau. This item refers to the Census Bureau’s promise of nondisclosure of that information to others.

County—The primary legal division of most states. Most are governmental units with powers defined by state law.

Edges shapefile—All linear features in the MAF/TIGER database are contained in the edges shapefile.

Enumeration at Transitory Locations (ETL) operation—Provides coverage for locations where people live in non-traditional housing that is transient or movable in nature. Most census questionnaires are mailed, or hand-delivered by census personnel, to known addresses in the Census Master Address File (MAF). However, due to changes in society, some people no longer maintain a traditional residence (house, apartment, condo, etc.), and have decided to live in boats, motorized recreational vehicles (RVs), trailers that are pulled by car or trucks, or any other type of housing that is movable or mobile, including tents. For operational purposes, we refer to these as ‘portable housing units.’

The type of Transitory Locations (TLs) that are included in the ETL are:

1. Recreational (RV) parks.

2. Marinas.

3. Campgrounds.

Feature—Any part of the landscape, whether natural (such as, a stream or ridge) or man-made (such as a road or power line). In a geographic context, features are any part of the landscape portrayed on a map, including nonvisible boundaries of legal entities, such as city limits or county lines.

Federal Information Processing Series (FIPS)—These are codes formerly known as Federal Information Processing Standards codes, until the National Institute of Standards and Technology (NIST) announced its decision in 2005 to remove geographic entity codes from its oversight. The Census Bureau continues to maintain and issue codes for geographic entities covered under FIPS oversight, albeit with a revised meaning for the FIPS acronym. Geographic entities covered under FIPS include states, counties, congressional districts, core based statistical areas, places, county subdivisions, sub-minor civil divisions, consolidated cities, and all types of American Indian, Alaska Native, and Native Hawaiian areas. FIPS codes are assigned alphabetically according to the name of the geographic entity and may change to maintain alphabetic sort when new entities are created or names change. FIPS codes for specific geographic entity types are usually unique within the next highest level of geographic entity with which a nesting relationship exists. For example, FIPS state, congressional district, and core based statistical area codes are unique within nation; FIPS county, place, county subdivision, and sub-minor civil division codes are unique within state. The codes for American Indian, Alaska Native, and Native Hawaiian areas also are unique within state; those areas in multiple states will have different codes for each state.

Geocodes—Codes that place an individual address in its correct geographic location, which, in census terms, includes the correct state, county, census tract, and census block codes. Because the Census Bureau counts people where they live, geocodes provide information to Census enumerators for locating an address. Accurate geocoding also ensures the Census Bureau counts housing units, and the people associated with them, in the correct census geography.

Geographic Information System (GIS)—A computer system for the storage, retrieval, and maintenance of information about the points, lines, and areas that represent the streets and roads, rivers, railroads, geographic entities, and other features on the surface of the Earth-information that previously was available only on paper maps.

Geographic Update Partnership Software (GUPS)—A self-contained GIS update and processing package provided by the Census Bureau for participation in a variety of Census geography programs, including 2020 LUCA. Pre-packaged to include all of the components for 2020 LUCA, the GUPS contains the Census Bureau’s Address List, address count list, and TIGER partnership shapefiles. GUPS allows the participant to add external geospatial data (shapefiles, geodatabases, and imagery) for comparison and update purposes. Delivery of all data (software, address list, address count list and shapefiles) is on DVD.

Governmental unit (GU)—A geographic entity established by legal action for the purpose of implementing specified governmental functions. Most governmental units provide a number of general government services and raise revenues (usually through taxing authority).

Group quarters (GQ)—A place where people live or stay normally owned or managed by an entity or organization providing housing and/or services for the residents. These services may include custodial or medical care as well as other types of assistance, and residency is commonly restricted to those receiving these services. People that live in a group quarters are usually not related. Group quarters include such places as college residence halls, residential treatment centers, skilled nursing facilities, group homes, military barracks, correctional facilities, workers’ dormitories, and facilities for people experiencing homelessness.

Highest elected official (HEO)—The person most responsible for the governmental activities of a local government. This person receives the LUCA Program invitation letter, and must designate a LUCA liaison, to participate in the 2020 LUCA Operation.

Housing unit (HU)—A single-family house, townhouse, mobile home, trailer, apartment, group of rooms, or a single room occupied as a separate living quarters or, if vacant, intended for occupancy as a separate living quarters. A separate living quarters is one in which one or more occupants (or intended occupants, if vacant) live separate from any other individual(s) in the building and have direct access to the living quarters without going through another living quarters, such as from outside the building or through a common hall.

Living quarters—Any site where people live, stay, or could live. Living quarters are classified as housing units or group quarters. They are usually found in structures intended for residential use, but also may be found in structures intended for nonresidential use as well as tents, vans, shelters for people without housing, dormitories, barracks, and so forth, or they might not be associated with a structure at all.

LUCA liaison—A person appointed by the highest elected official (HEO) of each jurisdiction to review the Census Bureau’s Address List and maps against local records to identify differences. This person is also known as the program primary liaison or designated liaison.

MAF/TIGER Database—The Census Bureau’s nationwide geographic database, which integrates the Master Address File (MAF) and Topologically Integrated Geographic Encoding and Referencing (TIGER) files.

Master Address File (MAF)—The Census Bureau’s nationwide database of all addresses and physical/location descriptions known to the Census Bureau used to support many of the Census Bureau’s operations. Besides containing mailing addresses and ZIP Codes, a MAF record also contains geographic information about the location of addresses. The Census Bureau’s Geography Division regularly updates the MAF/TIGER Database from various sources, including the United States Postal Service (USPS) Delivery Sequence File (DSF) and other sources of updates such as current surveys and locally provided sources.

Metadata—Describes the data content, coordinate system/projection, author, source, and other characteristics of GIS files.

Minor civil division (MCD)—A type of governmental unit that is the primary governmental or administrative subdivision of a county in many states. MCDs are identified by a variety of terms, such as town (in 8 states), township, and/or district, and include both functioning and nonfunctioning governmental entities.

Non-city style address—An address that does not have a house number and/or street name or may not include a complete house number and street name address. This includes rural route and box number address and highway contract route addresses, etc., which may include a box number, post office boxes and drawers, and general delivery.

Occupied housing unit—A housing unit is classified as occupied if it is the usual place of residence of the individual or group of persons living in it at the time of enumeration or if the occupants are only temporarily absent; for example, away on vacation. Occupied rooms or suites of rooms in hotels, motels, and similar places are classified as housing units only when occupied by permanent residents, that is, individuals for whom the facility is their usual place of residence.

Place—A concentration of population either legally bound as an incorporated place or identified by the Census Bureau as a census designated place.

Regional Office—One of six permanent Census Bureau offices distributed across the nation. Regional offices are responsible for the Census Bureau’s field operations.

Shapefile—Digital representations of geographic features, such as roads and boundaries used to create maps. A shapefile stores non-topological geometry and attribute information for the spatial features in a dataset. The Census Bureau provides county-based shapefiles in Environmental Systems Research Institute (Esri) shapefile format.

Street segment—The portion of a street or road between two features that intersect that street or road, such as other streets or roads, railroad tracks, streams, and governmental unit boundaries. The Census Bureau records the known address ranges for every street segment with city style addresses.

Structure Point (map spot)—A dot on a Census Bureau map, used to show the location of one or more living quarters. A maximum of 4-digits plus one alpha character is assigned within a census block to each structure point. Structure points are stored in the TIGER database and are protected by Title 13 U.S.C.

Topologically Integrated Geographic Encoding and Referencing (TIGER)—The Census Bureau’s digital map, including the geographic coordinates and names of streets, water features, other linear features, and boundaries for all jurisdictions and statistical areas that provide the geospatial framework for collecting and tabulating census data. TIGER also contains the structure coordinates of address records in the Master Address File (MAF) and address ranges along street features used for geocoding MAF records to census geography.

Transitory locations (TL)—Movable or mobile housing, or portable housing units, including boats, motorized recreational vehicles (RVs), tents, trailers that are pulled by cars or trucks, or any other type of portable housing.

Vacant housing unit—A habitable structure containing living quarters that is not occupied. New housing units not yet occupied are classified as vacant housing units if construction has reached a point where exterior windows and doors are installed and final usable floors and a roof are in place. Vacant units are excluded if they are open to the elements, or if there is positive evidence, such as a sign on the house, that the housing unit is to be demolished or has been condemned.

1 A structure point is a coordinate location that represents the location of one or more housing units and/or group quarters. Structure points are protected by Title 13, U.S.C. See Appendix A, Confidentiality and Security Guidelines.

2 A census tract is a small, relatively permanent statistical division of a county or statistically equivalent entity, delineated for the purpose of presenting Census Bureau statistical data.

3 A census block is a geographic area bounded by visible features, such as streets, roads, streams, and railroad tracks, and invisible features, such as the boundaries of governmental units and other legal entities. Census blocks are the smallest area for which the Census Bureau collects and tabulates statistical information.

4The Census Bureau does not endorse or recommend the use of any specific software to view its files. The program names included here are only examples of programs that are able to read digital files.

5 Address ranges are the lowest and highest address numbers used to identify structures along each side of a street segment that has city style addresses. Usually one side of the street has even address number and the opposite side has odd address numbers.

6 Address breaks are the city style addresses on each side of a boundary or at an intersection of a street with another street or feature.

7 A computerized file containing all delivery point address serviced by the USPS. The USPS updates the DSF continuously as its letter carriers identify addresses for new delivery points or changes in the status of existing addresses.

8 All shapefiles provided by the Census Bureau are in Environmental Systems Research Institute (Esri) format. The use of brand names does not represent an endorsement of a company or its products by the U.S. government. Due to the wide use of Esri products by our partners in the GIS community, and ubiquitous use of the shapefile format as a medium for GIS data exchange, the Census Bureau provides data in shapefile format.
