Census Geography/Maps/GIS

[Section Heading]


Census geography has changed over the years, as populations grow, decline, and move. Terminology has also changed from census to census. All census data is not available at every geographical level. In general, the more specific the geographic level, the less data is available.

This section includes any publications, datasets, or websites which provide information about decennial census geography or geospatial issues in general. The web pages for each individual census provides information about maps and GIS products which relate to that specific census.
