Census 2000 Redistricting Data Map Products

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.

[PDF] or denotes a file in Adobe’s Portable Document Format. To view the file, you will need the Adobe® Acrobat® Reader available free from Adobe.   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. Map Sheet Corner Point Coordinate files are geo-referenced listings of individual map sheets.

FINDING THE MAPS YOU NEED:

The map access system described below is a basic no-frills approach. However, we decided to speed up the process of getting the maps on-line rather than delay their release until we had the resources to design a more appropriate system. A more user-friendly system may be developed at a later date.

Go to the appropriate county subdirectory and download or view on-line the county index map. The county index map (see a sample) will show the county boundaries and the boundaries of any places within the county. It also will have an overlay of a grid of squares. Each square represents the area covered by one of the maps for that county. Using this grid, you can determine which map or maps cover the area of interest. At the center of each grid square you will find a map sheet number. This number is also a part of the file name for the PDF file of the map(s). It is in the last three positions before ".pdf". For example - pb25001_004.pdf is sheet number 4, shown in grid number 4 for Barnstable county, Massachusetts. With this information you can download or view the appropriate maps(s).

NOTE:  There may be instances in which the entire county is shown on a single County Block Map. For these counties, a single map file will appear in the appropriate county sub-directory. Download or view the map on-line. If there is more than one map file in the appropriate sub-directory, download or view the county index map on-line. A county sub-directory also may also have a parent sheet and one or more inset maps. In this case, there is no index sheet. Download or view the parent sheet to identify the inset maps.

File naming convention:  
State - stSS_statename (e.g. st25_massachusetts);
County - cSSCCC_countyname (e.g. st25001_barnstable);
Sheet/File - pbSSCCC_####.pdf (e.g. pb25001_004.pdf).

• For each county or statistically equivalent entity, these county-based maps show the boundaries and codes for Voting Districts and/or State Legislative Districts as delineated by the participating states in Phase 2, Voting District Project, of the Census 2000 Redistricting Data Program; the features underlying these boundaries; and the names of these features. These maps also show the boundaries and names of American Indian areas/Alaska Native areas/Hawaiian home lands, counties, county sub-divisions, and places. The maps will be available only for those states and counties that participated in the Voting District Project. Some states did not participate in the Census 2000 Redistricting Data Program and there are no Voting District/State Legislative District maps for these states.
