Using American FactFinder, the Census Bureau's data dissemination and online mapping engine, you can enter a street address and retrieve the associated census tract number, as well as additional Census 2000 data associated with the address. In the Census 2000 section, on the American FactFinder main page, select the "Enter a street address" link.
Institutions that need to file HMDA or CRA reports should check the Federal Financial Institutions Examination Council's (FFIEC) Web site to determine which vintage census tract (2000 or 1990) they should use when filing their HMDA or CRA reports. See Determining Census 2000 Tract Numbers for HMDA/CRA Reporting for information about various products available from the Census Bureau.
We have posted Census 2000 Tract numbers in two separate text files: Alabama through Montana and Nebraska through Wyoming and Puerto Rico, as an added resource for HMDA and CRA reporters. Each record provides the name and associated state and county FIPS codes and census tract numbers in hierarchical order. The leading and trailing zeros of the Census Tract numbers are not shown.
Each line is a separate record, and each record consists of four fields:

RELATE 2000 CENSUS TRACTS TO 1990 CENSUS TRACTS
As part of the Census 2000 geographic product series, the Census Bureau has produced Census Tract Relationship Files. (In previous censuses, this product was called a comparability file.) The purpose of the relationship files is to show how 1990 census tracts relate to Census 2000 census tracts. The files will consist of one record per each 1990 census tract/2000 census tract spatial set. A spatial census tract set is defined as the area that is uniquely shared between a 1990 census tract and a 2000 census tract.
The Census 2000 Census Tract Relationship Files, which include 56 sets of files (one set for each of the 50 states plus separate files for the District of Columbia, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands), are located on the Census 2000 Census Tract Relationship File Web page. An explanation of record layout and file structure, as well as examples of the main types of relationships that exist between 1990 and 2000 census tracts are also located on the Census 2000 Census Tract Relationship File Web page.
CENSUS TRACT OUTLINE MAPS (CENSUS 2000)
Note: For Census 2000, BNAs (Block Numbering Areas) have been incorporated into one program of census tracts. Therefore, there are no BNAs in Census 2000 geography, only census tracts.
SOFTWARE PRODUCTS FOR LOCATING 2000 CENSUS TRACTS
LandView® 5
LandView was developed in cooperation with the Environmental Protection Agency to map the location of hazardous waste sites and to provide basic census statistics for the areas around these sites. Because it can display the 2000 census tract boundaries over the network of streets, it is useful for matching addresses to census tracts. Since it is a map-based system, one can code rural addresses and new construction provided that one has a knowledge of the location of the address on the ground. New to version 5 is the "Address Finder" feature. This feature allows the user to type in a street name and ZIP Code to help determine where the address is located. Once the address is located on the map, one can then find the census tract and block group numbers. LandView 5 is distributed on Custom CD-ROM for $60 and a two-set DVD for $99. We also provide a demo
for those that may be potentially interested in this product.
There are a variety of tools available to determine in which 1990 census tract a particular address is located, as well as the poverty rate and other information related to that census tract. They range from paper maps to the Internet. Not all of these tools are equally appropriate for every user, however, and not all of the tools are equally capable in every situation. It should be noted that there are some parts of the country with areas identified as Block Numbering Areas (BNAs). These are the geographic equivalent to a census tract, and the two terms will be used interchangeably. This resource guide is in three parts, Part II - Census Bureau tools used to determine the 1990 Census Tract, Part III- Locating Census Tracts, and Part IV - Determining Poverty Rates.

American FactFinder
The American FactFinder Reference Maps feature to create
maps illustrating the boundaries, names, codes and numbers of various levels of geography, including Census Tract boundaries. Click on the "Reference Maps" link.
Next click on the appropriate State on the map. Select "Boundaries" under the "Display" heading. Select the Census Tract
layer and any other layers you wish to view. Select "View" under the "Map" heading. You will be able to zoom in or out
and pan in several directions until there is sufficient detail to see the tract boundaries.
1990 Census Tract/Block Numbering Area Outline Maps
The 1990 Census Tract Outline Maps are in ADOBE PDF format. These maps are re-creations of the 1990 Census Tract/BNA outline maps and differ from the original 1990 Census Tract Outline Maps. Similar to the 2000 Census Tract outline maps, these maps are
county-based and created for all 1990 Counties/County Equivalents in the
United States. All maps display the 1990 geography; however, the features displayed
on these maps are those shown on the Census 2000 maps. These maps show the boundaries and
numbers of the 1990 census tracts/BNAs as well as the named features
underlying the boundaries. They also show the boundaries, names and codes
for 1990 American Indian/Alaska Native areas, counties, county
subdivisions, and places. The scale of the maps will be optimized to keep
the number of map sheets for each area to a minimum, but the scale and
number of sheets will vary by the area size of the county and the
complexity of the census tracts.
To purchase paper copies of the 1990 Census Tract/Block Numbering Area Outline Maps, call the Census Bureau's Customer Services Center order desk at 301-763-4636. For more information about geographic products call 301-763-1128
SOFTWARE PRODUCTS FOR LOCATING 1990 CENSUS TRACTS
LandView® IV
LandView was developed in cooperation with the Environmental Protection Agency to map the location of hazardous waste sites and to provide
basic census statistics for the areas around these sites. Because it can display the 1990 census tract
boundaries over the network of streets, it is useful for matching addresses to census tracts.
This product is somewhat slower than the data base system used by the TIGER/Census Tract
Street Index. However, since it is a map-based system, one can code rural addresses and new
construction provided that one has a knowledge of the location of the address on the ground.
The product is distributed on
one DVD for $90.
One can also get the software and one county's worth of LandView III data free from the Right to Know Network's (RTK-Net) Web site.
TIGER/Census Tract Street Index®
This
product was developed specifically to match addresses to census tracts and is available as
one DVD or
eight CD-ROM (IBM-PC compatible).
Both the CD-ROM and DVD product comes with software that allows one to look up individual
addresses interactively and to determine the 1990 census tract number. Each CD-ROM costs
$60.00, $480.00 for 8-disc set, and contains the data for several states. The product will be able
to match most addresses with the exceptions of those with rural Post Office Box addresses and
those on streets that have been constructed since early 1998. Also available as a
paper listing by county.
A detailed description of this product is provided.
NOTE: The Census Bureau has not included Puerto Rico in the Census Tract Street Index (CTSI), Version 4 products because it's unique addressing system does not lend itself to the query system used in this product.
See Population, Land Area and Poverty Data for 1990 Census Tracts for listings of valid 1990 Census Tract codes by county within State.
Federal Depository Libraries
Another option is to contact a Federal Depository Library. These libraries keep copies of most Federal Government
publications and other resources. There are about 1,400 of these facilities across the country
(at least one in each Congressional district) and most of them have the reference materials (listed above)
necessary to determine the census tract for an address. Depending on their staff resources, they may do the
work for you or ask you to come in and do it yourself. To locate the nearest one to you call this toll free
number 1-888-293-6498 or visit the
Federal Depository
Web site.
State Data Centers
There are also sources of information in each state called State Data Centers.
These are organizations (state government agencies, university libraries, etc.) that have a partnership with
the Census Bureau to provide places to access Census data and to receive help in its use. There are one
or more in each state. They would use the same sources listed above. On the Internet you can find the
list of State Data Centers with addresses and
phone numbers, or you can call the Census Bureau at 301-763-1305. These organizations vary in the
resources available to provide assistance, and some must support their work with user fees.
Local Government Sources
If you are trying to determine the census tract for a particular location, one option is to try your local
government. The local planning department, the development commission, or council of governments
in your area may have this information since census tract data are often used for planning purposes.
Ask them for help in locating the census tract. The materials that they may have available to determine
the census tract include the 1990 Census Tract/Block Numbering Area Outline maps, the TIGER/Census
Tract Street Index, and LandView IV. These tools are described in more detail below.
PART IV
DETERMINING POVERTY RATES FOR A 1990 CENSUS TRACT
After you have matched addresses to census tract numbers, there are several ways to determine 1990 poverty rates
for those census tracts. In many libraries and in the State Data Centers there is a publication titled the Population and Housing Characteristics for Census Tracts and Block Numbering Areas (CPH-3) and a CD-ROM product titled STF-3A. Both show census tract data from the 1990 Census. The STF-3A CD-ROM can be purchased from the
Census Bureau. See
Population, Land Area and Poverty Data for 1990 Census Tracts
for listings by state of census tracts/BNAs.
For those users that are interested in using the Web, the Federal Financial Institution Examination Council's (FFIEC) service mentioned above also provides the poverty rate for 1990 census tracts.
The U.S. Census Bureau DOES NOT determine whether a census tract is a
"qualified census tract".
Qualified Census Tracts are Determined by the Department of Housing and Urban Development (HUD).
For more information on qualified census tracts, refer to the
"HUD USER" website, URL:
