1990 Census Tract/BNA Maps (PDF) by Texas County The maps listed here are in the Portable Document Format (PDF). To view these files you will need the Adobe® Acrobat® Reader Version 5.0 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. For each county or statistically equivalent entity, these county-based maps show the boundaries and numbers of the census tracts, and name the features underlying the boundaries. They also show the boundaries, names, and codes for American Indian areas/Alaska Native areas/Hawaiian home lands, counties, county sub-divisions and places. Click on the county name to 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 maps 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 Census Tract Outline 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.
