INTRODUCTION TO THE 2020 CENSUS LOCAL UPDATE OF
CENSUS ADDRESSES OPERATION
A.
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 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.

CHAPTER 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 for additional
terms and definitions.
1.1
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.
1.2
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.
1.3
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
address list you submit to the Census Bureau:
Houses, including townhouses, condominiums, and apartments.
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.
2020 Census LUCA Respondent Guide—Paper
Page 1
1.4
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 4.7.
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.
What are Group Quarters?
Group Quarters (GQ) 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 the
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.
2020 Census LUCA Respondent Guide—Paper
Page 2
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).
1.5
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 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 4.7.
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.
1.6
Census Bureau Addresses
1.6.1
Residential and Nonresidential Addresses
The Census Bureau divides all addresses into two use types, residential and
nonresidential. 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.
2020 Census LUCA Respondent Guide—Paper
Page 3
1.6.2
City Style Address Format
The Census Bureau classifies housing units and group quarters that have a house
number and street name address, for example, 212 Elm Street or 137 Clark Court,
Apt. 3, as city style addresses. In some instances, the house number may also include
an alpha character such as 35A or W9254. These are mailing address or addresses
that provide location for emergency services, such as police, fire, and rescue
(E-911 addresses).
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
Abbreviation). 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.
1.6.3
Non-city Style Address Format
The Census Bureau classifies addresses that do not include a house number and/or a
street name as non-city style addresses. Non-city style addresses may not include a
complete 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).
1.7
Census Tract
Census tracts are small, relatively permanent statistical subdivisions of a county or
statistically equivalent entity. 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.
2020 Census LUCA Respondent Guide—Paper
Page 4
1.8
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.
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 to 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.
1.9
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 geocodes or structure coordinates (latitude and longitude) for
the Census Bureau to process your address submissions. The Census Bureau will not
accept addresses without the geocodes 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.
1.10
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
2020 Census LUCA Respondent Guide—Paper
Page 5
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.
1.11
Strategies for Reviewing the 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 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 a multiunit address without multiunit
identifiers.
1.12
Local Address Sources
There are many possible sources of local address information. Some of these sources
may not match the Census 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.

CHAPTER 2. THE LUCA PAPER ADDRESS MATERIALS
This chapter discusses protecting Census Bureau address information and describes
the Census Address List, Address List Add Page, and Address Count List. The
examples shown may differ from the finalized materials. All address list and map
examples containing map spots use fictitious information.
2.1
Protecting Census Bureau Paper Address Information
The LUCA liaison accepts the responsibility for protecting and safeguarding the
confidential Census Bureau materials covered by Title 13, U.S.C. This includes the
Census Address List, 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 Confidentiality
Agreement Form (D-2005) is included in Appendix F. Be sure additional reviewers read
and understand the Confidentiality and Security Guidelines, Appendix A, before signing
and returning the Confidentiality Agreement Form (D-2005), Appendix F, to the Census
Bureau.
2.2
D-2007—The Census Address List
The Census 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. The paper address list is on 8 ½ x 14 inch (legal size) paper.
Each sheet contains six addresses. Figure 1. 2020 Census Paper Address List
Tract/Block Sort Example displays an example of the tract/block sort of the Census
Address List. Figure 2. 2020 Census Paper Address List Street Name/House, Unit,
Census Tract, and Census Block Number Sort Example displays an example of the
street name/house number sort of the Census Address List.
The Census Address List for county participants may contain ungeocoded addresses.
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. Refer to Section 4.6, Ungeocoded Addresses—
Counties Only.
2.2.1
Heading Area
The top of each page of the paper address list is the heading area. This area contains:

CHAPTER 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, to all
participants that selected the Paper or Paper/Adobe Portable Document Format (PDF)
product preference for the map selection. Use these maps to geocode your addresses.
o
The focus of the 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 PDF 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 containing PDF small format (8.5”x14”) block maps including 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 containing 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. All map examples depicting map spots use fictitious information for illustration,
instruction, and training purposes only.
3.1
Reading a Large Format LUCA Paper Map
There are three types of paper map sheets:
1. Index Sheets
2. Parent Sheets
3. Inset Sheets
3.1.1
3.1.2
Index Sheets—for reference (if more than one map sheet)
Covers the entire extent of your jurisdiction.
Divided into numbered grids that correspond to the parent sheets.
Each numbered grid 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.
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 location of census tracts and blocks within your jurisdiction on the parent sheet.
2020 Census LUCA Respondent Guide—Paper
Page 18
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 or adding a geocode to a new address.
3.1.3
3.1.4
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., A).
May be multiple sheets (e.g., A1, A2).
Shows detail for features and geographic areas.
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.

Boundary Improvements
The PDF 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.

CHAPTER 4. REVIEWING AND UPDATING THE ADDRESS
LIST, ADDRESS LIST ADD PAGE, AND PAPER
MAPS
4.1
Adding Residential Addresses to the Address List Add Page
Use the Address List Add Page to add residential addresses for your jurisdiction not
shown on the Census Address List or to add addresses deleted from the Census
Address List and added to incorporate corrections that are not editable on the Census
Address List. Make sure to print all entries completely and legibly.
When adding an address, you must include the location of the housing unit or group
quarters structure by providing either the census geographic codes (i.e., state county
code, census tract number, and census block number) or map spot location (by placing
a dot on the map or by providing structure latitude/longitude coordinates on the Address
List Add Page. You can find the geographic codes on your LUCA materials.
If you choose to add structure coordinates, provide a minimum of eight characters
including the decimal, e.g., 42.58953 for latitude and minimum of nine characters for the
longitude including the negative and decimal, e.g., -87.58953.
4.2
Adding Records with Similar Information
When adding more than two addresses where the information is the same, you can print
the information in the first and last entry of each column then draw an arrow down to
indicate the similar information. The exceptions to this are the Apt/Unit Number (4f)
since you must enter each individual unit number for multiunit structures and when
adding individual Unique Map Spot Numbers (5).
Note: You may draw an arrow down in column 4a, Complete Address Number, only if the
house number is the same for all buildings or units. See Figure 35. Adding New City
Style Addresses for a New Street (Training—Fictitious Information).
4.3
Adding Residential City Style Addresses to the Address List
Add Page
When adding addresses to multiple pages, be sure to enter the appropriate Line
Number in column 1 for each address. For example, you can add four addresses to
each page of the Address List Add Page. Column 1 on page one begins with 1 and
ends with 4.
On the next page, page two, enter 5 in column 1, Line Number and end with 8.
Continue adding the line number sequence for each page as needed.
Note: Multiunit identifiers are required for all new added addresses and address updates for
multiunit structures for LUCA. The Census Bureau will not process an address without a
multiunit identifier.

Updating Addresses on the Census Address List
Action Codes
There are four action codes used to make updates to the Census Address List. You can
make updates to residential addresses only. You must include the appropriate action
code with each address record that you update. The Census Bureau will process only
those address records that contain an action code.
C—Correct this address.
D—Delete this address.
J—Address is not in this jurisdiction.
N—Address is nonresidential.
The C Action Code
Print a “C” in the Action Code, column 3, on the Census Address List 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 ZIP Code.
2020 Census LUCA Respondent Guide—Paper

The D Action Code
Do not make corrections to any other columns when entering the “D” action code.
Print a “D” in the Action Code, column 3, on the Address List for the following
situations:
Housing unit or multiunit structure no longer exists, is uninhabitable, or is a duplicate.
Street or addresses along a street that no longer exists.
Print a “D” in the Action Code, column 3, on the Census Address List then use the
Address List Add Page to add corrected addresses for the following situations:
Incorrect house number.
Incorrect apartment or unit number.
Single housing unit converted to a multiunit structure.
Multiunit structure converted to a single housing unit.
Single housing unit converted to a group quarters.

Print an “N” in the Action Code, column 3, on the Census Address List for addresses
that are listed on the Address List but are used for any purpose other than residential
such as:
Businesses.
Schools.
Churches.
Government offices.
Before entering an “N” action code, ensure that the structure does not contain a housing
unit. 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.
Do not make corrections to any other columns for nonresidential addresses.
4.4.1
Correcting Addresses (The C Action Code)
The following is a list of a few examples using the “C” Action Code:
Correcting a street and addresses located in an incorrect block.
Correcting an address located in an incorrect block.
Correcting a street name.
2020 Census LUCA Respondent Guide—Paper
Page 57
4.4.1.1 Scenario: Correcting the Location of a Street and its Associated
Addresses
Correcting the location of a street located in an incorrect census block is a two-step
process. First correct affected address on the Census Address List using the
instructions below, then identify the correct location of the street on the map.
The Census Address List shows 100 through 117 S Holdener St, map spots 38-52, as
located in census block 1003. According to local sources, S Holdener St is located
south of Pampas St in census block 1009.
On the Census Address List:
Print a “C” in the Action Code (3) column for the first and last block number that needs
correction.
Draw an arrow down from the first entry to the last entry.
In the Census Block (4c) column, cross out the incorrect block number and print the
correct block number above it. In this example, cross out 1003 and print 1009 above it.
Draw an arrow down from the first entry to the last entry.
Repeat this procedure for all the Census Address List sheets containing the block
number that needs correction.
Refer to Figure 48. Correcting the Location of a Street and its Associated
Addresses on the Census Address List.
Indicate the correction on the paper map.
See Figure 49. Identifying the Location of a Street and its Associated Addresses
on the Small Format Paper Map (Training—Fictitious Information) and Figure 50.

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
numbers and the opposite side has odd address numbers.
7
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.

4.4.1.2 Scenario: Correcting an Address Located in an Incorrect Census Block
During your address review, you may find an address (house number/street name) is
correct but the structure is located in an incorrect census block.
The Census Address List shows 411 Alexander Blvd located in block 2001. Local
sources indicate that 411 Alexander Blvd is located in block 2005.
On the Census Address List:
Print a “C” in the Action Code (3) column.
In the Census Block (4c) column, cross out the incorrect block number and print the
correct block number above it. In this example, cross out 2001 and print 2005 above it.
Optional: If you know the approximate location of the address in the correct block, cross
out the map spot number in the Map Spot Number (8) column and print a unique map
spot number above it. In this example, the assigned map spot number is C1, representing
a correction.
Refer to Figure 51. Correcting an Address Located in an Incorrect Block on the
Census Address List.
Indicate the correction on the small format paper map.
Refer to Figure 52. Correcting an Address Located in an Incorrect Block on the
Small Format Paper Map (Training—Fictitious Information).

Draw an arrow down from the incorrect map
spot to the correct location.
Figure 52. Correcting an Address Located in an Incorrect Block on
the Small Format Paper Map (Training—Fictitious Information)
4.4.1.3 Scenario: Correcting an Incorrect Street Name
Incorrect street names on the Census Address List may happen for a variety of reasons.
For instance, they may occur when the Census Bureau receives the USPS Delivery
Sequence File (DSF)8 that contains an incorrect street spelling or as an incorrect entry
during Census Bureau field operations.
The Census Address List and map incorrectly shows Nale Pl instead of Nail St, the
correct street name.
On the Census Address List:
Print a “C” in the Action Code (3) column for the first and last addresses that are affected
by the street name correction.
Draw an arrow down from the first entry to the last entry.
In the Complete Street Name (4b) column, cross out the incorrect name, in this
example, Nale Pl, and print the correct name, Nail St, above it for the first street name
and the last street name that needs correction.
Draw an arrow down from the first entry to the last entry.
Repeat this procedure for all the Address List sheets containing the street name that
needs correction.
See Figure 53. Correcting a Street Name on the Census Address List. Correct the
street name on the small format paper maps as shown in Figure 54. Correcting a
Street Name on the Small Format Paper Map (Training—Fictitious Information).

On the Small Format Paper Map:
Using a colored pencil, cross out the
incorrect name, Nale St and print the
correct name, Nail St, above it.
Use double hatch marks to show the
extent of the name change. In this
instance, the entire street needs
correction.
If there is an alternate street name, print
the alternate street name in parentheses.
For example, Nail St (Co Rd 9).
Figure 54. Correcting a Street Name on the Small Format Paper
Map (Training—Fictitious Information)
4.4.1.4 Scenario: Correcting a Street Name that Extends Multiple Blocks
Identify all the Census Address List sheets containing the addresses located along the
incorrect street name for each block affected by the correction.
On the Census Address List:
Print a “C” in the Action Code (3) column for the first street name and last street name
that needs correction.
Draw an arrow down from the first entry to the last entry.
In the Complete Street Name (4b) column, cross out the incorrect name and print the
correct street name above it for the first street name and last street name that needs
correction.
Draw an arrow down from the first entry to the last entry.
Repeat this procedure for all the Address List sheets containing the street name that
needs correction.
On the Small Format Paper Map:
1. Print all the block maps containing the incorrect street name for each block affected by
the street name correction.
2. On each sheet, use double hatch marks to show the extent of the name change.
3. If there is an alternate street name, print the alternate street name in parentheses. Refer
to Figure 54.

4.4.2
Deleting Addresses (The D Action Code)
Enter a “D” in the Action Code (3) column 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
correction 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 to the Address List Add Page
using the “A” action code.
Duplicate addresses are those incorrectly listed twice on the Census Address List for
the same residential address. For example, the Census Address List lists 101 Main St
and 101 S Main St. Your local address sources indicate that there is a 101 S Main St
but no 101 Main St. After confirming that 101 Main St does not exist, you would enter a
“D” in the Action Code (3) column for 101 Main St.
Do not make corrections to any other columns on the Census Address List for a
deleted address.
The following is a list of a few examples using the “D” Action Code shown in this
section:
Deleting addresses that no longer exist.
Deleting an incorrect house number and adding the corrected address to the Address List
Add Page.
Deleting incorrect apartment/unit numbers and adding the corrected addresses to the
Address List Add Page.
Deleting a single housing unit converted to a multiunit structure on the Census Address
List and adding multiunit address to the Address List Add Page.
Deleting addresses for a multiunit converted to a single housing unit and adding the
single housing unit to the Address List Add Page.
Deleting a group quarters address converted to a single housing unit and adding the
single housing unit address to the Address List Add Page.

group quarters address to the Address List Add Page.
4.4.2.1 Scenario: Deleting Addresses that no Longer Exist on a Section of a
Street on the Address List
This example is for a section of street that no longer exists. The housing units along the
street section were demolished.
On the Census Address List:
A section of S Holdener St in census block 1003 no longer exists and the housing units
along this section were demolished.

Non-City Style Addresses
The Census Bureau classifies addresses that do not include a house number and/or a
street name as non-city style addresses. Non-city style addresses also may include an
incomplete house number or street name address. Frequently used non-city style
mailing addresses that are included on the Census Address List are:
Physical location description.
Rural route and box number.
Highway contract route and box number.
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.
4.5.1
Adding Non-city Style Addresses to the Address List Add Page
The most common non-city style addresses on the Census Address List are the
physical location description and identifying map spot, and rural route and highway
contract route and box numbers. The following instructions provide a few examples of
how to add non-city style addresses missing on the Census Address List.
4.5.1.1 Scenario: Adding New Physical Location Description Addresses to the
Address List Add Page
To add a new physical location description address to the Address List Add Page, in
addition to a well-defined location description you must provide:
Geocodes and a map spot on the paper map, and/or
The latitude and longitude of the housing unit or group quarters structure.
One area of Winter County uses PO Boxes at the local post office to receive their mail.
There is no city style (E-911 address, e.g., house number and street name) location
addresses or mailbox delivery addresses. The only way to locate the housing unit
structures in this area are with a physical location description.
2020 Census LUCA Respondent Guide—Paper
Page 95
The area north of Aca St includes three new housing units. The physical location
descriptions and their identifying map spots are missing from the Address List and map.
On the Address List Add Page:

with 5 and end with 8. Continue adding the line number sequence on each page.)
Enter the information in section 2, Census Geographic Location of Address, including
the State County Code (2a) number, Census Tract Number (2b), and Census Block
Number (2c). If there are multiple entries, print the information in the first and last lines
needed and draw an arrow down from the first entry to the last entry.
Note: If you choose, you may enter the structure latitude and longitude coordinate information
in addition to or rather than the State County Code, Census Tract Number, and Census
Block Number in Section 4, space permitting. Refer to Figure 72.
Enter the Complete Street Name (4b) for each new location description address, if
known.
Identify each new housing unit with a Physical Location Description (4e). Provide a
well-defined description.

4.5.1.2 Scenario: Adding Rural Route and Box Number Addresses to the Address
List Add Page
Because rural routes and highway contract routes are mailbox delivery routes served by
rural carriers to deliver and collect mail from roadside mailboxes, adding these types of
addresses must include additional information to locate the housing unit or group
quarters. In addition to the rural route or highway contract number and box number
address, you must provide:
Map spot on the map, and/or housing unit or group quarters structure latitude and
longitude.

Ungeocoded Addresses—Counties Only
The Census Address List for 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. You may use the “C,” “D,” “N,” and “J” action
codes to include geocodes (census tract and census block) for correcting addresses
(C), deleting addresses (D), identifying nonresidential addresses (N), and identifying
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. 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.
4.6.1
Adding Geocodes for Ungeocoded Addresses
If your county receives ungeocoded addresses, they are listed on the last page(s) of
your Census Address List. Please provide the census tract and census block for
ungeocoded addresses, if known, to ensure that the Census Bureau can enumerate
each housing unit in the correct location.
4.6.1.1 Scenario: Adding Geocodes for Ungeocoded Addresses on the Census
Address List
The Census Address List for Winter County contains several new city style addresses
that are missing geocodes.
Print a “C” in the Action Code (3) column for the first and last addresses that need
geocodes added.
Draw an arrow down from the first entry to the last entry.
Print the census tract number in the Census Tract (4b) column and the census block
number in the Census Block (4c) column and draw an arrow down in each column from
the first entry to the last entry.
Optional: If you know the approximate location of each address, assign a unique Map
Spot Number in column 8.
Note: If you choose, you may enter the optional structure latitude and longitude coordinate
information, if known, in addition to or rather than the TRACT and BLOCK in section 4,
space permitting or in column 10, Map Spot Coordinates. Refer to Figure 81 and
Figure 82. You must add a minimum of five digits after the decimal point.
Refer to Figure 79. Ungeocoded Addresses on the Census Address List (Counties

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 not named 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.
2020 Census LUCA Respondent Guide—Paper
Page 113
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 LUCA. 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.

CHAPTER 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 Institute 9
(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.
7F
Shapefile Background
In order to submit digital feature information, you must have a Geographic Information
System (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. 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.
5.1.2
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 paper address list and digital maps, the disc you received contains
the non-Title 13 Address Count List and the TIGER Partnership shapefiles in a folder
9
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.
2020 Census LUCA Respondent Guide—Paper
Page 125
named “shape.” Upon completion of the initial setup of files by launching the executable
file to place the contents of the disc in the 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.
5.1.3
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 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 5 to identify the type of feature modification in the
CHG_TYPE field of the edges shapefile. Specific examples of these updates in Section
5.1.4 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.

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 5 for the change type codes
and their descriptions.
5.1.4
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 5. Record the change type code within the CHNG_TYPE field in the
edges shapefile attribute table for each feature in which an update occurs.

6.1
Preparing Your Updated LUCA Materials for Submission
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 102. Please include the Inventory Form for the Return/Submission Materials (D2011) in Appendix G with your returned materials. Follow the procedures for shipping
Title 13 materials discussed in this chapter and referenced in Appendix A, the
Confidentiality and Security Guidelines (D-2004).
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, your updates may not be incorporated in the MAF/TIGER database.
Your updates are temporary until the verification operation provides confirmation.
If after your review, you determined that the Census Address List is correct and you
have no address updates, please complete the form letter D-2079 included with your
LUCA materials and return it in the enclosed pre-addressed, postage-paid envelope.
If you select that 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.
6.1.1
Sorting the Paper Census Address List and Address List Add Page
All Census Address List and Address List Add Pages (and copies) are Title 13
materials. Ensure that you store all copies in a secure location.
Separate the updated pages from the pages without updates.
Make a copy of the updated pages of the address list and the Address List Add Page to
use during the feedback phase of LUCA.
Bundle only the updated pages to prepare for shipping. Organize the pages by:
The Census Address List.
The Address List Add Page.
Note: Return only those pages containing updates.
6.1.2
Sorting the Paper Maps for Submission
To return the printed PDF small format paper maps and any large format paper maps
with updates to the Census Bureau:

CHAPTER 7. NEXT STEPS
Congratulations on the completion of your 2020 Census 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, they will
process your files for validation. After validation concludes, 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 LUCA 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) 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)
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) as required by law.
Filing an appeal is optional and is not a requirement of the LUCA operation.

APPENDIX A CONFIDENTIALITY AND SECURITY
GUIDELINES
Introduction
Federal law, under Title 13 of the United States Code (U.S.C.), requires the U.S.
Census Bureau to maintain the confidentiality of the information it collects. The Census
Bureau takes this responsibility very seriously. Respondents place their trust in the
Census Bureau each time they complete a survey or an interview. This trust in
confidentiality is critical to the success of the Census Bureau’s mission to collect and
report the most accurate data possible. To uphold the law, the Census Bureau requires
that any individuals with access to Title 13 materials adhere to the prescribed
confidentiality and security guidelines.
Title 13, U.S. Code
Chapter 1, Section 9 of Title 13, U.S. Code states: “Neither the Secretary, nor any other
officer or employee of the Department of Commerce or bureau or agency thereof, or
local government census liaison, may, except as provided in section 8 or 16 or chapter
10 of this title….
Use the information furnished under the provisions of this title for any purpose other than
the statistical purposes for which it is supplied; or
Make any publication whereby the data furnished by any particular establishment or
individual under this title can be identified; or
Permit anyone other than the sworn officers and employees of the Department or bureau
or agency thereof to examine the individual reports.”
In 1994, under Public Law 103-430, the U.S. Congress amended Chapter 1 of Title 13
to allow the local government census liaison to review and update the Census Bureau’s
address information for their jurisdiction. Although the amendment allows official local
government access, the amendment reaffirmed the confidential nature of the Census
Bureau’s address information. Census information protected under Title 13 includes:
Everything on a completed or partially completed questionnaire or any information
obtained in a personal or telephone interview.
Individual addresses maintained by the Census Bureau, including those shared with
governments through the 2020 Census Local Update of Census Addresses Operation
(LUCA).
Digital or paper maps with latitude/longitude coordinate data that identify the location of
living quarters (structure points).
The penalty for the wrongful disclosure or release of information protected by Title 13 is a
fine of not more than $250,000 or imprisonment for not more than 5 years, or both, as set
by Section 214 of the Code and the Uniform Sentencing Act of 1984.
Title 13 U.S.C. does not apply to generalized address information, such as address
range data available in the Census Bureau’s digital products or address counts by
census block.
2020 Census LUCA Respondent Guide—Paper

The Confidentiality Agreement
To participate in LUCA, a government must designate a LUCA liaison. The LUCA
liaison, LUCA reviewers, and anyone with access to Title 13 materials must sign the
Confidentiality Agreement. The Census Bureau will not deliver LUCA materials to a
participant until we have received the completed and signed Confidentiality
Agreement and the Confidentiality and Security Checklist.
The Census Bureau’s Title 13 data, including addresses and latitude/longitude
coordinate data (structure points), cannot be used to create, update, nor modify a tribal,
state, or local jurisdiction’s address list or database.
A signature on the Confidentiality Agreement constitutes a legal agreement by each
individual to keep confidential Census Bureau Title 13 data and abide by the security
guidelines outlined below. While access to Title 13 materials is temporary, the
commitment to keep the information confidential is effective for a lifetime.
Security Guidelines
The LUCA liaison accepts the responsibility for protecting and safeguarding the LUCA
materials. The liaison must restrict access to the Census Bureau’s information covered
under Title 13 to those individuals who have signed the Confidentiality Agreement.
A.4.1
Protecting Digital Title 13 Materials
Operating systems, programs, applications, and data are collectively referred to as
Information Technology (IT) systems in this document. Any IT systems used for LUCA
participation must be accessible only to those who have signed the Confidentiality
Agreement. Your IT systems should restrict the read, write, and delete functions to all
Title 13 materials.
Digital 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 computers with Title 13 materials unattended. Log-off computers, lock
terminals, and lock the room when not in use.
Label all digital media and every printed page of any paper materials produced from Title
13 digital 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).”
Do not send backup digital media off-site. Store in a secured area. Do not mix, store, or
back-up LUCA data with other data.
2020 Census LUCA Respondent Guide—Paper
Page A-2
Clear dedicated digital media containing Title 13 materials before reuse. Overwrite Title
13 digital data a minimum 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 Confidentiality Agreement.
Password Guidelines
The IT systems must use logon 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
A.4.2
A.4.3
anyone who has signed the Confidentiality Agreement.
Must consist of at least twelve, nonblank characters consisting of at least one alphabet
letter and either one number or one special character (for example: $,*, or &).
Reject passwords that are the same as the user-ID or that have been 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.
Protecting Paper Title 13 Materials
Do not leave Title 13 materials unattended. Secure all Title 13 materials in a locked room.
If possible, store Title 13 materials in locked desks or cabinets.
Copy only the Title 13 materials necessary to complete the LUCA review. Do not leave
the copy machine unattended while making copies. All copied materials containing Title
13 information must bear the statement:
“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).”
Do not disclose precise or even anecdotal information about Census Bureau addresses
or locations to anyone who has not signed the Confidentiality Agreement.
Reporting an Incident
If you discover that any Title 13 materials have been viewed by unauthorized persons or
are missing from your inventory, you must:
Contact the Census Bureau through the Census Incident Response Team (CIRT) at
(301) 763-3333 within 24 hours. You must provide the following information:
Jurisdiction Name.
Date and time of the incident.
Name of the contact person.
Phone number of contact person.
2020 Census LUCA Respondent Guide—Paper
Page A-3
A.4.4
Site address of incident.
Immediately secure all remaining materials. Prohibit any further access, by anyone,
including the LUCA liaison and anyone who signed the Confidentiality Agreement.
Census Bureau staff will contact your office within 48 hours with information on how to
proceed.
On-site Visits
The Census Bureau may make an on-site visit to review a participant’s security
procedures. The Census Bureau will strive not to disrupt office operations. A visit may
include a review of:
Storage and handling of Title 13 materials.
Employee access to Title 13 materials.
Physical safeguard of stored Title 13 materials.
IT Systems, including use of passwords.
Employee awareness of their responsibilities to Title 13 materials.
A.4.5
Destruction of Census Bureau Confidential Materials
After the entire LUCA operation has concluded, all Title 13 materials must be
destroyed (preferred method) or returned according to the Census Bureau’s specific
guidelines.
The LUCA liaison is required to verify the destruction or return of any Title 13 materials,
both paper and digital, including all paper copies, backup files, etc., by signing and
returning the Destruction or Return of Title 13, U.S.C. Materials form. In addition,
anyone who signed the Confidentiality Agreement is required to sign this form once their
participation in LUCA has ended. Should any liaison, reviewer, or anyone who signed
the Confidentiality Agreement leave before the completion of LUCA, they must sign and
date this form. If any liaison, reviewer, or anyone who signed the Confidentiality
Agreement is unable to sign and date the form, the current liaison must sign and date
on their behalf. Only individuals who signed the Confidentiality Agreement are permitted
to destroy Title 13 materials:
Never deposit Title 13 materials in a trash or recycle container, or dispose of information
in a landfill before destruction procedures are completed.
Destruction must prevent recognition or reconstruction of paper or digital Title 13
materials. Use one of the following methods:
Shredding or pulping.
Chemical decomposition.
Pulverizing (such as, hammer mills, choppers, etc.).
Burning (facility approved by the Environmental Protection Agency).
Clear dedicated digital media containing Title 13 materials before reuse. Overwrite
Title 13 digital data minimally three times using a commercial disk utility program.
2020 Census LUCA Respondent Guide—Paper
Page A-4
Clearing or sanitizing all print servers and multi-function printing or scanning devices
with stored images or print files containing Title 13 data.
Destroying CDs and DVDs using a shredder or other method suitable for rendering
them un-usable.
Note: Hand tearing is an unacceptable method of disposal before destruction.
See the National Institute of Standards and Technology, Special Publication 800-88,
Revision 1, Guidelines for Media Sanitization for further information on acceptable
methods for digital media and office equipment sanitization.
A.4.6
Returning Census Bureau Title 13 Materials
After the entire LUCA operation has concluded, all Title 13 materials must be
destroyed (preferred method) or returned according to the Census Bureau’s specific
guidelines. If you choose to return the Title 13 materials rather than destroying them,
follow these guidelines:
Ship the Title 13 materials, double-wrapping them by using an inner and an outer
envelope (or container), one within the other. These should be durable enough to prevent
someone from viewing or tampering with the enclosed material.
Label both sides of the inner envelope (or container) with the notice:
“DISCLOSURE PROHIBITED BY Title 13, U.S.C.”
Place the inner envelope (or container) into the outer envelope.
Use the mailing label that was included in the initial mail-out of materials. If you have
misplaced the mailing label, please contact the Census Bureau to have a replacement
label sent to you.
Include with the returned materials, a signed D-2012, Destruction or Return of Title 13,
U.S.C. Materials Form. Ensure that all reviewers and anyone with access to the Title 13
LUCA materials signs this form.
If you do not use the mailing label, ship using a service that provides tracking information,
such as U.S. Postal Service trackable delivery, FedEx, United Parcel Service (UPS), or
similar service.

APPENDIX M 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 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 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.
2020 Census LUCA Respondent Guide—Paper

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. Carnivals

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 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 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
2020 Census LUCA Respondent Guide—Paper
Page M-4
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
2020 Census LUCA Respondent Guide—Paper
Page M-5
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.
