The United States Census Bureau is responsible for the Census of Population and Housing. It also gathers other national demographic and economic data. As part of the United States Department of Commerce, the Census Bureau serves as a leading source of data about America’s people and economy.

The 1990 and 2000 decennial census boundary files available here are selected generalized extracts from the Census Bureau’s TIGER geographic database and are designed for use in a Geographic Information System (GIS) or similar mapping system. The cartographic boundary files on this site are available in ARC/INFO EXPORT (.e00) format, ArcView Shapefile (.shp) format, and ARC/INFO Ungenerate (ASCII) format. These are the boundary files without the demographic data in the attribute tables. Tabular data may be downloaded from American Factfinder (http://factfinder2.census.gov/) and used in conjunction with the boundary files.
