Frequently Asked Questions (FAQs):

It is a good idea to read these questions.


Redistricting Data from Bureau:

Census 2000 Redistricting Data (Public Law 94-171) including Data Tentatively Scheduled for Release Week of Charts.  Note that Census 2000 redistricting data for a particular state may not not be available American FactFinder on the same day that it is released to the public.


Census 2000 Census Geography:

Census Blocks for; The Census Bureau has proposed a new census block number format and collection/tabulation block strategy for Census 2000.

Geographic Definitions; an alphabetical listing of census geography;

Geographic Areas Reference Manual (GARM);The Geographic Areas Reference Manual describes in great detail the basic geographic entities the Census Bureau uses in its various data tabulations and documents the purposes, definitions, standards, criteria, and procedures used to select, define, delineate, and revise these geographic entities.   Since the publication of the GARM in November 1994, there have been two major changes in geographicareas for Census 2000: The Census Bureau will no longer include the Republic of Palau in U. S. censuses because it is an independent state.  All entities referred to as "block numbering areas" (BNAs) in 1990 will become census tracts. The 1994 manual is available in print in the SSRC-reading room (C 3.6/2: G 29/4).

Metropolitan Areas Reference Definitions; The general concept of a metropolitan area is that of a large population nucleus, together with adjacent communities having a high degree of social and economic integration with that core. Metropolitan areas comprise one or more entire counties, except in New England, where cities and towns are the basic geographic units.  The Office of Management and Budget (OMB) defines metropolitan areas for purposes of collecting, tabulating, and publishing federal data. Metropolitan area definitions result from applying published standards to Census Bureau data.

An alphabetical arrangement of census geographic terms with a detailed explanation of census hierarchical presentation of data.


Census Maps:

Census 2000 Redistricting Data Map Products will include three types of maps were prepared to accompany the Census 2000 Redistricting Data:  County Block Maps (Census 2000), Voting District/State Legislative District Outline Maps (Census 2000), and Census Tract Outline Maps (Census 2000).

Redistricting data map products will not be available for: American Samoa, Guam, Northern Mariana Islands, U.S. Minor Outlying Islands (Midway) and the U.S. Virgin Islands. However, Census 2000 Block and Census 2000 Census Tract Outline maps will be available at a later date for these areas.

The maps listed here are in the Portable Document Format (PDF). To view these files you will need the Adobe® Acrobat®  Reader Version 4.0 or above, which is available free of charge from the Adobe web site. The maps were created as 33" x 36" sheets, however, the Adobe Reader allows one to pan and zoom within the image on your computer screen. These PDF maps are arranged in sub-directories by map type. Within each map type sub-directory, the map files are stored in county sub-directories within the appropriate state sub-directory. Within each county folder there will be an index sheet file to help the user identify individual maps.

NOTE:  These maps will be released as they successfully complete the production and quality check process. We cannot predict the timing of when individual state files will complete this process, therefore, we cannot provide estimated release dates for individual states. For details see www pages on tips for finding, viewing, and prints map images.  

Redistricting Census 2000 TIGER/Line Files: The Redistricting Census 2000 TIGER/Line files are specifically intended to support the needs of the redistricting community. This version of the TIGER/Line files contains all the Census 2000 entities EXCEPT FOR the ZIP Code® Tabulation Areas (ZCTAsTM), nor do they contain the updated address ranges based on the final Census 2000 information.  The Census 2000 TIGER/Line files, scheduled for release in the second quarter of 2001, will include files for these areas, as well as the ZCTA information and the updated Census 2000 address ranges.  The Census Bureau is   providing the TIGER/Line files in ASCII text format only and the data are NOT in the form of map images. To create maps with the TIGER/Line files, one would typically use a Geographic Information System (GIS) package or other mapping software.  For details, see the www page above. See http://www.census.gov/geo/www/tiger/rd_2ktiger/ctychng.html for county changes between 1990 and 2000. See http://www.census.gov/geo/www/ for Tiger products.


The Census Questionnaires:

The decennial census uses both short- and long-form questionnaires to gather information. The short form asks a limited number of basic questions. These questions are asked of all people and housing units, and are often referred to as 100-percent questions because they are asked of the entire population. The long form asks more detailed information from approximately a1-in-6 sample, and includes the 100-percent questions as well as questions on education, employment, income, ancestry, homeowner costs, units in a structure, number of rooms, plumbing facilities, etc.

The American Community Survey is a new approach for collecting accurate, timely information needed for critical government functions. This new approach provides accurate, up-to-date profiles of America's communities every year. Community leaders and other data users will have timely information for planning and evaluating public programs for everyone from newborns to the elderly.

The American Community Survey is a way to provide the data communities need every year instead of once in ten years. It is an on-going survey that the Census Bureau plans will replace the long form in the 2010 Census.

Full implementation of the survey is planned for 2003 in every county of the United States if Congress allocates the necessary funding. The fully implemented survey would include three million households. Data are collected by mail with follow-up calls and visits from Census Bureau staff if a household does not respond.
