The 2010 Census New Construction Program
The United States Census Bureau wants to ensure that the residential address list
for the 2010 Census is as complete and as accurate as possible on April 1, 2010.
The Census address list has been updated with the assistance of tribal, state, and
local governments through the Local Update of Census Addresses (LUCA)
program. Subsequently, the Census Bureau updated the list through a nationwide
field canvass. The New Construction Program is the final opportunity for you to
submit new city-style housing unit addresses for which basic construction began
during or after March 2009 and are expected to be closed to the elements (final
roof, windows, and doors) by Census Day, April 1, 2010.
New Construction Program participation allows you to submit your local address
list file of city-style 1 single structure residential addresses only, in a predefined
Census Bureau computer-readable format. The Census Bureau will only accept
local address files (city-style addresses only) in the predefined format as
explained in Chapter 4.
The New Construction Program has been offered to all jurisdictions that have
census blocks in which 2010 Census questionnaires are delivered by the U.S.
Postal Service to predominantly city-style addresses. For other areas, the Census
Bureau will have its employees hand deliver questionnaires to the housing units in
each census block, update the Census address list where newly built units are
missing from the list, and deliver a questionnaire to each new address (or actually
conduct the enumeration at each housing unit) as they complete their assignment.
In the New Construction Program, participants can only add housing unit
addresses. This program does not allow for address deletions or corrections or for
changes to the governmental unit boundaries shown on the maps. The Census
1
A city-style address consists of a house number and street name and zip code; 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. See Chapter 2 for a complete definition.

New Construction Program
Bureau updates the boundaries through its annual Boundary and Annexation
Survey.
For governments choosing to use the Census Bureau’s MAF/TIGER Partnership
Software (MTPS) that was included with your materials, please see the separate
MTPS User Guide.
Definition of Qualifying New Construction
New construction is defined as any residential housing unit for which basic
construction began during or after March 2009 and is expected to be closed to the
elements (final roof, windows, and doors) by Census Day, April 1, 2010. The
Census Bureau defines basic construction as closing the structure and having it
protected from the elements, that is, having a roof, windows, and doors in place.
The structure must be within the New Construction Program review area shown
on the Census Bureau maps.

Chapter 1: Introduction to the 2010 Census New Construction Program
Background
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 File 2 with the latest version
of the U.S. Postal Service’s (USPS) Delivery Sequence File 3 (DSF) and by a
field address listing method in areas with non-city style addresses. 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 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.
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 tracts4 , census blocks 5 , etc.)
used to tabulate decennial census data. The TIGER® database also includes
address ranges 6 along streets that have city-style addresses and the hierarchy
of 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 update
sources include current household surveys, special censuses, and local sources.

The 1990 residential address list used to label questionnaires, control the mail response check-in operation, and
determine the nonresponse follow-up workload.
3
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.
4
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.
5
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.
6
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.

Introduction
Chapter 2 explains some of the terms and concepts used by the Census Bureau
and recommended strategies for your New Construction 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.
What is an Acceptable New Construction Program Housing Unit?
The following types of housing units are acceptable and should be included on
your address list:
•
•
•
•
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 are expected to be closed to
the elements (final roof, windows, and doors) will be completed by
Census Day, April 1, 2010.

Chapter 2: Before You Begin Your Review
Unacceptable Types of Housing Units
Exclude the following unacceptable types of housing units or structures and
all group quarters addresses from your New Construction Program
submission. Unacceptable housing units or structures include:
•
•
•
•
•
•
•
Condemned or scheduled for demolition.
Being converted or remodeled for nonresidential purposes.
Used solely for storage.
Used solely as offices or businesses in which no one is living.
Used solely for ceremonial purposes.
Under construction and will not be habitable (closed to the elements
with final roof, windows, and doors) on Census Day, April 1, 2010.
Group Quarters (see description below). The Census Bureau programs:
Group Quarters Validation (GQV) and Group Quarters Advance Visit
(GQAV) will be the mechanisms used to collect group quarters data.
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.
Below are examples of group quarters that are not acceptable and should not
be included in your New Construction Program submission:
•
•
•
•
•
•
•
•
•
•

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;
you can include the addresses for these housing units but not those for the
group quarters.

Chapter 2: Before You Begin Your Review
Census Bureau Addresses
Residential and Nonresidential Addresses
The Census Bureau classifies all addresses as either residential and
nonresidential. Residential addresses are for housing units and/or group
quarters where one or more people could live. Nonresidential addresses are
for structures or units within a structure that do not serve as a residence, such
as commercial establishments, schools, government offices, and churches.
Nonresidential addresses are not accepted in the New Construction Program.
Some structures can contain both residential and nonresidential units, even
though they have the same address, i.e. an apartment over a store or a home
with an office. You should include these types of residential units that exist
within the same structure as nonresidential units with your New Construction
address updates.
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 a
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 C, Unit Designation Abbreviations). The Census Bureau and
the USPS treat these unit designators as part of the housing unit address,
and they are included as part of each such census address record.
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 do not include a complete house number and street name
address. The majority of non-city 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 non-city style
mailing addresses include:
•
9
General delivery.
New Construction Program
Chapter 2: Before You Begin Your Review
•
•
•
Rural route and box number.
Highway contract route and box number.
Post Office box only delivery.
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.
Census Tracts
Census tracts are small, relatively permanent statistical subdivisions of a
county or statistically equivalent entity, delineated for presenting Census
Bureau statistical data.
The proposed criterion 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 block numbers consist of 4-digits, and may
include a single alpha character suffix reflecting a boundary change or added
feature (e.g. 3001A and 3001B).
Census Blocks
A Census block is an area bounded by visible features such as streets, roads,
streams, and railroad tracks and nonvisible 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 consist of 4-digits, and
may include a single alpha character suffix reflecting a boundary change or
added feature (e.g. 3001A and 3001B).
Note: The 2010 Decennial Census New Construction Program addresses are
coded to current census block/geography.
New Construction Program
10
Chapter 2: Before You Begin Your Review
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.
You can find these census geographic codes on your New Construction
materials.
Strategies for Conducting the New Construction Program Review
You must decide for yourself how to conduct the New Construction Program.
Consider your available time, the information you have readily available, and
the staff and computer resources you have.
Local Address Sources
There are many possible sources of local address information. The following
list provides suggestions for local address source materials:
•
•
•
•
•
•
•
•
•

an “*” as the unit designation where not known.
This allowance can no longer be accommodated at
this late juncture in the 2010 Decennial Census
process. The Census Bureau requires a unit
designation for each new residence identified in a
multiunit structure. The existence of a complete
address provides our field staff with the information
needed to accurately identify and enumerate each
newly constructed unit.

Shapefiles
Shapefiles require the use of GIS software. The Census Bureau provides
county-based shapefile layers in Environmental Systems Research Institute 7
(ESRI) shapefile format. Participants can use shapefiles to assist in
geocoding New Construction addresses.
To geocode addresses to census blocks, a tab block shapefile is included. The
tab block shapefile contains New Construction blocks. Ineligible blocks will
be appropriately shaded and will not be available for updates of new
addresses.
The shapefiles, created from the MAF/TIGER database, allow you to geocode
address updates. All linear features in the MAF/TIGER database are
contained in the edges shapefile.
In order to use shapefiles, you must have a GIS. If you wish to use the Census
Bureau’s MAF-TIGER Partnership Software (MTPS) that was included with

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.

New Construction Review Area
There may be Census blocks in your jurisdiction that are not
eligible for the New Construction Program. The TABBLOCK
shapefile contains an attribute titled NCELIGIBLE (for New
Construction eligible). New Construction eligible blocks will have a
“Y” in the NC ELIGIBLE field of the TABBLOCK shapefile
(Refer to Table 4.1 for an example of a NC TABBLOCK Table.
NCELIGIBLE is highlighted in the table). When geocoding any
address updates you must provide the State Fips Code, County Fips
Code, Census Tract Code, and Tabulation Block. These attributes will
be found in the in the NC TABBLOCK Table as found in figure 4.3.

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
21
New Construction Program
Chapter 4: The Census Bureau Maps
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 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’s coordinate system.
Remember, the shapefiles are for geocoding purposes only. The New
Construction will not accept any feature updates.
If you encounter problems, please contact the Help Desk toll free at 1866-919-5822 for assistance.

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.
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.

Glossary
34
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 person most responsible for the
governmental activities of a local government. This person receives the New
Construction Program invitation letter, and must designate a New Construction 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.
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
Glossary

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
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. Group Quarters are NOT included in the 2010 New Construction Program.
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 government's jurisdiction, and thus bounds the area of
New Construction responsibility.
New Construction liaison – Also known as the program primary liaison or designated
liaison. A person voluntarily appointed by the chief executive/highest elected official of
each jurisdiction to review the Census Bureau’s address list and maps against local
records to identify differences.

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.
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.
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 Census Center – One of 12 Census Bureau centers responsible for the Census
Bureau’s office and field operations within its region.
Shapefile – Spatial and attribute file used to represent geographic features such as streets
and boundaries. Shapefiles can represent point, line, or area features and require GIS or
mapping software.
Glossary
36
37
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. 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
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.
