Census Tract Outline Maps (Census 2000) [PDF]
Description: These maps show the boundaries and numbers of the census tracts as well as the named features underlying the boundaries. They also show the boundaries, names and codes for American Indian/Alaska Native/Hawaiian home land 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.
File naming convention:
State - stSS_statename (e.g. st25_Massachusetts/);
County - cSSCCC_countyname (e.g. c25005_Bristol/ st25_Massachusetts/);
Sheet number/File - ctSSCCC_###.pdf (e.g. CT25003_001.pdf).
1990 Census Tract Outline Maps [PDF]
Description: It is important to note that these PDF 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.
File naming convention:
State - stSS_statename (e.g. st12_Florida/);
County - SSCCC_countyname (e.g. 12099_PalmBeach/ st12_Florida/);
Sheet number/File - 90TSSCCC_(sheet number).pdf (e.g. 90T12009_001.pdf).
FINDING THE MAPS YOU NEED:
Go to the appropriate county sub-directory and download or view on-line the county index map. The county index map 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 map sheets for that county. Using this grid, determine which map or maps cover the area of interest. Within 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". With this information, you can download or view the appropriate maps(s).
NOTE:
In many counties, the entire county is shown on a single map. For these counties, there will be a single map file in the county sub-directory. Download or view the map on-line. If there is more than one map file in the county sub-directory, download or view the county index map on-line to locate the appropriate map sheet.
