The 2010 Decennial Census Local Update of Census Addresses (LUCA)
Program
The Local Update of Census Addresses (LUCA) Program is an integral part of
the 2010 Census activities that utilizes the expertise of tribal, state, and local
governments to improve the accuracy and completeness of the address list
used to take the census.
The U.S. Census Bureau invited the Governor (Chief Executive/Highest
Elected Official), of your state to participate in this program. Your state
selected Option 3, Non-Title 13 Local Address List Submission. This option
allows you to:
•
Review the Census Bureau’s address count list for your state. This list
is for reference purposes only.
•
Submit your state address list file of city-style1 single unit or multiunit
structure and group quarters2residential addresses in a predefined
Census Bureau computer-readable format. The Census Bureau will
only accept local address file (city-style addresses only) in the
predefined format as explained in Chapter 4.
•
Identify any additions, deletions, or corrections to roads, or other
physical features by submitting an updated version of the digital map
file (shapefile) provided by the Census Bureau.
1
The term city-style address is defined as an address that consists of a house number and street or road name, for
example, 201 Main Street. However, the address may or may not be used for the delivery of mail, and may include
apartment numbers/designations or similar identifiers. See Chapter 2 for a complete definition.
2
A group quarters is a place where people live or stay that is normally owned or managed by an entity or organization
providing housing and/or services for the residents. See Chapter 2 for a complete definition.

Chapter 1: Introduction to the 2010 Decennial Census Local Update of Census
Addresses (LUCA) Program
Background
The Census Address List Improvement Act
The Census Address List Improvement Act of 1994 (Public Law 103-430)
strengthened the Census Bureau’s partnership capabilities with tribal, state,
and local governments by expanding the methods the Census Bureau could use
to exchange address information. Designed to improve the accuracy of the
Census Bureau’s address list, the Act authorized the Census Bureau to provide
individual addresses to officials of tribal, state, and local governments who
agreed to conditions of confidentiality. Census 2000 marked the first
decennial census for which the Census Bureau could provide its address list
for review to governments that signed the required confidentiality agreement.
The Census Bureau’s Master Address File (MAF)
In preparation for Census 2000, the Census Bureau created the Master Address
File (MAF) by merging the 1990 Address Control File3 with the latest version
of the U.S. Postal Service’s (USPS) Delivery Sequence File4 (DSF). The
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 noncity-style
addresses (e.g., rural route or post office box number), the address record may
contain additional information such as a location description.
The Topologically Integrated Geographic Encoding and Referencing
(TIGER®) Database
Address records in the MAF are linked to feature segments 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 all jurisdictions and statistical areas (census tracts5, census blocks6, etc.)
used to tabulate decennial census data. The TIGER® database also includes
address ranges7 along streets that have city-style addresses and the hierarchy of

The 1990 residential address list used to label questionnaires, control the mail response check-in operation, and
determine the nonresponse follow-up workload.
4
A computerized file containing all delivery point addresses serviced by the U.S. Postal Service (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.
5
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.
6
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.
7
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 other side has
odd address numbers.

Addresses (LUCA) Program
census geographic area codes from the state level down to individual census
blocks (www.census.gov/geo/www/geodiagram.html). By linking address
records in the MAF to the TIGER® database, the Census Bureau is able to
identify street segments along which an individual address exists and
determine the geographic code that applies to that address.
The Census Bureau’s Geography Division regularly updates the MAF/TIGER
database from various sources. In addition to the USPS DSF, other sources of
updates include current household surveys, special censuses, and local sources.

Introduction
Chapter 2 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.
What is a Housing Unit?
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.
The following types of housing units are acceptable and should be included on
your address list that you submit to the Census Bureau:
•
•
•
•

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.
Any housing units under construction that will be habitable (closed to
the elements with final roof, windows, and doors) on Census Day,
April 1, 2010.

Chapter 2: Before You Begin Your Review
What are Group Quarters?
A place where people live or stay, in a group living arrangement, that is
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. People living in group quarters are usually not
related to each other.
The following types of group quarters are acceptable and should be included
on your address list that you submit to the Census Bureau:
•
•
•
•
•
•
•
•
•
•
Correctional facilities.
Juvenile facilities.
Nursing homes.
Hospitals with long-term care facilities.
College or university dormitories, fraternities, sororities.
Dormitories for workers.
Religious group quarters.
Shelters.
Group homes.
Any group quarters under construction that will be habitable (closed to
the elements with final roof, windows, and doors) on Census Day,
April 1, 2010.
Note: Housing units and group quarters can exist within the same structure.
Unacceptable Types of Housing Units and Group Quarters
Exclude the following unacceptable types of housing units and group quarters
addresses from your address list:
•
•
•
•
•
•
Condemned or scheduled for demolition.
Being converted or remodeled for nonresidential purposes.

Chapter 2: Before You Begin Your Review
Census Bureau Addresses
Residential and Nonresidential Addresses
The Census Bureau divides all addresses in 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.
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.
Address Formats
City-Style Address Format
The Census Bureau refers to housing units and group quarters addresses
that have a house number and street name address, for example, 212 Elm
Street or 137 Clark Ct., Apt. 316, as city-style addresses. In some
instances, the house number may also include an alpha character such as
35A or W9254. These addresses are used for mailing or to 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.” (See
Appendix B, Unit Designation Abbreviations.) The Census Bureau and the
U.S. Postal Service treat these unit designators as part of the housing unit
address, and they are included in each affected census address record.
Noncity-Style Address Format
The Census Bureau classifies addresses that do not include a house
number and/or a street name as noncity-style addresses. Noncity-style
addresses also may not include a complete house number and street name
address. The majority of noncity-style addresses are located in the more
sparsely settled areas of the United States; however, they may exist in
small or medium sized towns as well. Frequently used noncity-style
mailing addresses include:
•
•
•
•
8
General delivery.
Rural route and box number.
Highway contract route and box number.
Post Office box only delivery.
Option 3-Non-Title 13 Local Address List Submission State
Chapter 2: Before You Begin Your Review
Noncity-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 location descriptions (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).
Census Tract
Census tracts are small, relatively permanent statistical subdivisions of a
county or statistically equivalent entity, delineated for presenting Census
Bureau statistical data.
The proposed criteria for census tracts for the 2010 Census is that they contain
a minimum of 1,200 people with an optimal population of 4,000.
Census tract boundaries are delineated with the intention of being stable over
many decades, so they generally follow relatively permanent visible features.
However, they may follow governmental unit boundaries and other nonvisible features in some instances. Census tract boundaries never cross state
or county (or statistically equivalent entity) boundaries.
Each census tract is uniquely numbered within a county and contains
numerous census blocks. Census tract numbers contain up to 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. Leading zeros are not shown on Census
Bureau materials.
Note: When using the Census Bureau shapefiles to geocode an address to a
Census Tract number, use the Tractlabel attribute field on the curtracts
(current tracts) shapefile.
Census Block
A census block is an area bounded by visible features such as streets, roads,
streams, and railroad tracks and non-visible features such as the boundaries of
governmental units and other legal entities. A block is the smallest
geographic area for which the Census Bureau collects and tabulates statistical
data.
Census blocks may look like a city block or may be large and irregularly
shaped, depending upon features. The boundary of a state or a county is
always a block boundary.
Census blocks are numbered within census tracts and are unique to the census
tract to which they belong. Census block numbers contain a 4-digit number,
Option 3-Non-Title 13 Local Address List Submission State
9
Chapter 2: Before You Begin Your Review
and may include a single alpha character suffix, reflecting a boundary change
or added features (e.g. 3001A and 3001B).
Note: The 2010 Decennial Census LUCA Program addresses are coded to
current census block/geography.
What is Geocoding?
In order to process your address submissions, the Census Bureau requires the
inclusion of census geographic code information. This link to census
geography is referred to as geocoding. Geocoding places an individual
address in its correct geographic location, which includes the correct state,
county, census tract, and census block codes.
Because the Census Bureau counts people where they live, census geographic
code information or 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 census geographic code information for the Census Bureau to
process your address submissions. The Census Bureau will not accept
addresses without census geographic codes (geocodes) including the state,
county, census tract, and census block codes.
Note: When using the Census Bureau shapefiles to geocode an address to a
Census Tract number, use the Tractlabel attribute field on the curtracts
(current tracts) shapefile.
You can find these census geographic codes on your LUCA materials.
Strategies for Conducting the LUCA Program Review
You must decide for yourself how to conduct the LUCA program review.
Consider your available time, the information you have readily available, and
the staff and computer resources you have. If resources are limited, the
Census Bureau recommends focusing on areas where addresses are more
likely to be missed or incorrect. For example:
•
•
•
•
•
•
•
•
10
Areas of new housing construction.
E-911 address conversion areas.
Areas that have changed from single-family homes to multifamily
homes and vice versa.
Warehouses that have been converted to residential lofts.
New mobile home parks or new scattered mobile homes.
Apartment buildings with irregular or missing numbering schemes for
the individual units.
Annexed land.
Areas along jurisdictional boundaries.

Address Sources
There are many possible sources of address information. Differences in your
count of residential addresses and the Census Bureau’s count of addresses are
a good indication of where change is taking place and can help you identify
addresses that you need to add to your address list. The following list
provides suggestions for address source materials:
•
•
•
•
•
•
•
•
•
•
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, 2010).
E-911 address files.
Housing occupancy permits.
Planning or zoning records.
Local utility records.
Drivers’ license files.
Annexation records.
Assessment or taxation files.
Voter registration files.
School enrollment records.

The Address Count List Files
The File Formats
Introduction
The Census Bureau’s address count list file your state selected to review are
included on your CD-ROM. This chapter discusses:
•
File name and format.
•
Software requirements.
•
How to open the file.
The Address Count List Files
The address count list (ACL) file contains the residential address counts for
each census block within a county or county-equivalent your state selected to
review. The state level file is named, STxx.exe.
Where,
“ST” = 2 character, alpha entity type, “State”
and
“xx” = 2-digit, numeric entity ID for your state.
For example, the 4-character state file name for New York is:
ST36.exe
Where,
“ST” is state and “36” is the state code for New York.
The file name for the address count list for each county or county
equivalent is:
LUCA_ACL_STXXyyy.txt
Where:
“ST” = 2 character, alpha entity type, “State”
XX = 2-digit, numeric state code and,
yyy = 3-digit, numeric county FIPS code.

Chapter 3: The LUCA Program’s Computer-Readable Address List and Address
Count List
For example the address count list file name for Prince George’s County,
Maryland is:
LUCA_ACL_ST24033.txt,
Where, “ST” is State, “24” is the state code for Maryland, and “033” is
the county code for Prince George’s County.
Locating the Name of a County or Count Equivalent Using the County Code
Each filename contains a unique Federal Information Processing Standards
(FIPs) code. To locate the name of the county or county equivalent
associated with the county FIPS code visit,
•
The Census Bureau recommends that you make a copy of each of
the files and place them on the hard drive of a computer that is
password protected. This will preserve the original files should
you need to look at an original record or require another original
copy of the file.
•
To help keep your work organized, create a new directory or new
folder on your hard drive. Copy the files from the CD-ROM into
that directory or folder.
Software Requirements
The address count list files you receive are pipe-delimited ( | ) ASCII text
files, meaning they can be viewed and read as letters and numbers with a text
editor. All spreadsheet and database programs can read and understand these
text files.
Many commercial spreadsheet and database programs can open the LUCA
files. Use spreadsheet programs such as Microsoft Excel or Lotus 123 to
open, view, and edit small files. For larger files, use a database program such
as Corel Paradox, QuattroPro, Microsoft Access, or dBase8.
Note: Some computer programs that can open and view pipe-delimited text
files cannot save an edited file in the correct format. Make sure your program
has the ability to save or export a file with pipe-delimited fields. Call the Help
Desk toll free at 1-866-919-5822 if you need assistance or more information.

THE CENSUS BUREAU SHAPEFILES
Introduction
Shapefiles
Submitting Shapefile Feature Information
Metadata
Digital File Submission
Introduction
The Census Bureau provides you with shapefiles as a reference for locating
and geocoding individual addresses, and for updating and correcting features.
Shapefiles
Shapefiles require the use of GIS software. The Census Bureau provides
county-based shapefile layers in Environmental Systems Research Institute9
(ESRI) shapefile format. Participants that submit shapefiles with feature
updates must follow Census Bureau requirements.
The shapefiles, created from the MAF/TIGER database, allow you to submit
map feature updates electronically. All linear features in the MAF/TIGER
database are contained in the edges shapefile. Use the edges shapefile to add,
delete, or change linear feature attributes.
To geocode addresses to census blocks, a tabblock shapefile is included.
In addition to an edges shapefile, the Census Bureau provides shapefiles for
legal boundaries. Do not edit the legal boundaries layer.
For more details on the contents of the shapefiles, view the readme.txt file that
is included in the CD-ROM containing your shapefiles.
Submitting Shapefile Feature Information
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.
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.

Option 3-Non-Title 13 Local Address List Submission State
Chapter 5: The Census Bureau Shapefiles
The Census Bureau’s Shapefile Coordinate System and Projection
Information
All shapefiles provided by the Census Bureau are in the following
unprojected 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
General File Setup Guidelines
Upon receipt of your shapefiles, follow the setup guidelines listed
below before beginning actual updates:
•
Open the CD and enclosed zip file to ensure it contains the
shapefiles for your entity.
•
Copy and decompress the shapefiles to a directory on your
server or hard drive.
•
Open the shapefile in a GIS.
Note: If you are using GIS software that does not contain a shapefile
translator, please contact the Help Desk toll free at 1-866-919-5822 for
further instructions.
Changing Our Coordinate System to Match Yours
Our files are in GCS_NAD83 format. Please feel free to project these
files into your local coordinate system projection. 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 ArcView to update files, please activate
and utilize ArcView’s ‘Projection Utility Wizard’ extension. If using
ArcGIS, please use its “Projection Utilities” in ArcToolbox.
MAF/TIGER extract shapefiles contain defined projection information
in the *.PRJ file. Both ArcView and ArcGIS access the *.PRJ file for
projection information; therefore, there is no need for you to define
these parameters before changing the file coordinate system.
Option 3-Non-Title 13 Local Address List Submission State
23
Chapter 5: The Census Bureau Shapefiles
In addition, if your files are in a datum other than NAD83, you must
geographically transform our files to match your datum. Most GIS
software has tools for performing geographic transformations on files.
If you transform the files to your local coordinate system, we request
that you convert them back to the GCS_NAD83 format before
submitting the file to the Census Bureau. If you encounter problems
transforming our files, please contact the Help Desk toll free at
1-866-919-5822 for assistance.
Feature Information
If you have reviewed your features using our shapefiles and have
determined that the Census Bureau needs to add, remove, or rename
features in a given area, you may submit your modifications in a
separate layer. To move or correct the shape of a feature, first delete
the feature then add the correction.
Use the appropriate update code located in the coding scheme as
shown in Figure 5.3 to identify the type of feature modification needed
for submission.
If any issues arise with the shapefiles that you submit, your Census
Bureau Regional Office will attempt to contact you to clarify the issue.
If clarification is not made prior to our project deadline, the updates
may not be incorporated into MAF/TIGER. Your updates are
considered temporary until their existence is confirmed during our
Address Canvassing Operation.
Updating the Feature Shapefile
Use the edges layer to provide all feature updates to the Census
Bureau’s shapefile.
Edges Layer Data Dictionary
The data dictionary defines the attribute information for each feature
contained in the edges layer. See Figure 5.1 for an example of the
edges layer data dictionary.

•
TLID is the TIGER/Line® ID
•
The MAF/TIGER Feature Class Code or MTFCC is used to
identify the most noticeable characteristic of a feature.
o The MTFCC is a five-character code; the first character is
a letter describing the feature class. For example, streets
and roads are identified as S1400.
o The Census Feature Class Codes or CFCC were recently
changed to the MTFCC. A crosswalk is on the following
page as well as in the readme.txt file on your CD-ROM.
• If the FIDELITY flag contains a value of “1,” the Census Bureau
was unable to maintain the boundary’s shape during the
MAF/TIGER Accuracy Improvement Process (MTAIP).
o The MTAIP project acquired geographic information
system (GIS) files, aerial photography, and GPS data from
various sources nationwide to update the TIGER® database.
o One of the primary goals of the project was to develop a
highly accurate geographic database of the United States.
The Census Bureau focused on improving the accuracy of
street feature coordinates to provide base information
suitable for use with GPS-equipped hand held devices that
would facilitate the gathering of accurate location and
census information for all living quarters and workplaces.
o To aid the Census Bureau in developing a highly accurate
geographic database, please review all line segments (not
just roads) in the Census Bureau’s edges layer for lines
with a fidelity flag value of “1.”
•
FULLNAME is the feature name.
•
CHNG_TYPE is the type of digital linear update.

author, source, and other characteristics of GIS files are critical for Census
Bureau staff to efficiently and accurately process files. The Census
Bureau requires that a metadata text file accompany every GIS file and
layer submitted.
The Federal Geographic Data Committee’s (FGDC) Content Standard for
Digital Spatial Metadata provides a national standard that enables the datasharing public to easily locate critical information about a file and ensure
that no critical information is omitted inadvertently when creating
metadata. For this reason, the Census Bureau requests that metadata be
submitted using this standard. For information about the FGDC and its
geospatial metadata standards, please visit .
The Census Bureau requires that the following sections of the FGDC
metadata form be completed:
•
Citation (information about the originator, publication date, title
edition, and other publications or information).
•
Description (section that contains an abstract describing your data
set).
•
Time period of content (section that describes the vintage of the
data).
•
Spatial domain (information about bounding coordinates).
•
Point of contact (general contact information).
•
Data quality information (information about attribute accuracy).
•
Spatial reference information (section on coordinate
system/projection of the data set).
•
Entity and attribute information (section that describes the contents
of your table).
To help you fulfill the requirement of filling out and submitting metadata,
the Census Bureau suggests visiting the United States Geological Survey
(USGS) Web site at . This site contains useful
information about FGDC compliant metadata, from which one can read
about metadata frequently asked questions, view FGDC metadata
examples, and connect to other FGDC related Web pages. The FGDC 's
metadata URL is .

Chapter 5: The Census Bureau Shapefiles
Moreover, if you are using Arc/Info, the following link points to a useful
Arc Macro Language (AML) tool that, when executed, completes most of
the required sections of the metadata form automatically
. (This AML is a
product of the Illinois State Geological Survey.)
Note: ESRI’s ArcCatalog also has an embedded program that uses the
FGDC standard in its creation of geospatial metadata.
If you have questions regarding the metadata requirements, please contact
the Help Desk toll free at 1-866-919-5822.
Digital File Submission
Use the following as a guide to ensure that you have included all the
required layers for each county.
•
Save the changes for each county in a separate feature update layer
file. Name each file:
LUCA__LN_changes.shp (where XX is the state
code and the yyy is the county code)
The feature update layer must include:
o A value in its “CHNG_TYPE” field that indicates the type
of change.
o Only feature updates (do not include unmodified features).

Glossary
Address breaks – Address breaks are the city-style addresses on each side of a boundary
or at an intersection of a 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.
American Indian area – A Census Bureau term that refers to any or all of the following
entities: American Indian reservation, American Indian off-reservation trust land,
Oklahoma tribal statistical area, joint use area, American Indian tribal subdivision, tribal
designated statistical area, and state designated American Indian statistical area.
American Indian off-reservation trust land – The United States holds title for specific
areas in trust for the benefit of federally recognized American Indian tribes (tribal trust
land) or for individual American Indians (individual trust land). Although trust land may
be located on or off a reservation, the Census Bureau recognizes and tabulates data only
for off-reservation trust land. Census data always associate off-reservation trust land with
a specific federally recognized reservation or tribal government.
American Indian reservation – A federal American Indian reservation is an area that
has been set aside by the United States for the use of one or more federally recognized
American Indian tribes. It covers territory over which a tribe(s) has primary
governmental authority. Its boundary is defined by tribal treaty, agreement, executive or
secretarial order, federal statute, or judicial determination. A state American Indian
reservation is an area that a state government has allocated to a tribe recognized by that
state, but not by the federal government.
Block number – A 4-digit number, plus 1 alpha character block suffix, if applicable,
used by the Census Bureau to identify each census block. Census blocks are numbered
uniquely within each census tract.
Boundary – A line, either invisible or coincident with a visible feature that identifies the
extent of a geographic entity, such as a census tract, city, or county.
Boundary and Annexation Survey – An annual survey to collect information about
selected legally defined geographic areas. The BAS is used to update information about
the legal boundaries and names of all governmental units in the United States.
Census Bureau address list – A nationwide list of all housing unit and group quarters
addresses known to the Census Bureau. In addition to the mailing address and ZIP Code,
the Address List may identify the location of each housing unit and group quarters.
38
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.
Census block number –Census block numbers contain a 4-digit number plus a 1-digit
alpha character, if applicable, e.g. 3001A. Suffixes, such as 2011A and 2011B, reflect
boundary changes as well as added features.
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 division of a county or
statistically equivalent entity, delineated for the purpose of presenting Census Bureau
statistical data. Census tracts never cross the boundary of a county or statistically
equivalent entity, but may split other geographic entities; e.g., minor civil divisions and
places.
Census tract number – Unique numbers to identify census tracts within a county or
statistically equivalent entity. Census tract numbers contain up to 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. Leading zeros are not shown on Census Bureau maps.
Chief executive/highest elected official – The elected or appointed person who is the
chief executive official of a governmental unit and is most responsible for the
governmental activities of the governmental unit, such as the governor of a state, chair of
a county commission, or mayor of an incorporated place. This person receives the LUCA
Program invitation letter, and must designate a LUCA liaison, if desired.
City-style address – An address that consists of a house number and street name; for
example, 201 Main Street. 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.
39
County – The primary legal division of most states. Most are governmental units with
powers defined by state law.
Delivery Sequence File (DSF) – A computerized file containing all delivery point
addresses serviced by the U.S. Postal Service (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.
Edges shapefile – All linear features in the MAF/TIGER database are contained in the
edges shapefile. Use the edges shapefile to add, delete, or change linear feature
attributes.
Enumeration – The process of interviewing people and recording the information
on census forms.
Feature – Any part of the landscape, whether natural (such as, a stream or ridge) or
artificial (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 Standards codes (FIPS codes) – a standardized set of
numeric or alphabetic codes issued by the National Institute of Standards and Technology
(NIST) to ensure uniform identification of geographic entities through all federal
government agencies. The entities covered include: states and statistically equivalent
entities, counties and statistically equivalent entities, named populated and related
location entities (such as places and county subdivisions), and American Indian and
Alaska Native areas.
Geocodes – Codes that place an individual address in its correct geographic location,
which includes the correct state, county, census tract, and census block codes.
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.
Governmental unit – 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 – A place where people live or stay, in a group living arrangement, that
is 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
40
is commonly restricted to those receiving these services. People living in group quarters
are usually not related to each other.
Group quarters include such places as correctional facilities, juvenile facilities, nursing
homes, hospitals with long-term care facilities, college or university dormitories,
fraternities, sororities, dormitories for workers, religious group quarters, shelters, group
homes.
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.
Legal boundary – The legally defined boundary of a governmental unit, usually
referring to a county, minor civil division, or incorporated place. The legal boundary
identifies the area within a local or state government's jurisdiction, and thus bounds the
area of LUCA responsibility.
LUCA state liaison – Also known as the program primary liaison or designated liaison.
A person voluntarily appointed by the chief executive/highest elected official of each
state to review the Census Bureau’s address list and maps against local records to
identify differences.
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.
MAF/TIGER Partnership Software (MTPS) – A GIS application provided by the
Census Bureau that has customized functionality required by Census Bureau geographic
partnership programs.
Map Sheet to Block Number Relationship List – A list identifying census block
numbers and the Census Bureau map(s) on which each block is located.
Master Address File (MAF) – A nationwide database of all addresses 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.
Metadata – describes the data content, coordinate system/projection, author,
source, and other characteristics of GIS files.
41
Minor civil division (MCD) – A type of governmental unit that is the primary
governmental or administrative subdivision of a county. 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.
Noncity-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 12 permanent Census Bureau offices responsible for the
Census Bureau’s office and field operations within its region.
Shapefile – Data set used to represent geographic features such as streets and
boundaries. Shapefiles can represent point, line, or area features and require GIS or
mapping software.
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 – A dot on a Census Bureau map, used to show the location of
one or more living quarters. A 4-digit number plus 1-digit alpha character
assigned within a census block to each structure point. Structure points are stored
in the TIGER® database.
®
Topologically Integrated Geographic Encoding and Referencing (TIGER ) – A
computer database that contains a digital representation of all map features (streets,
roads, rivers, railroads, lakes, and so forth) required to support Census Bureau
operations, the related attributes for each, and the geographic identification codes for all
entities used by the Census Bureau to tabulate data for the United States, Puerto Rico,
and Island Areas.
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
42
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 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.
