Geography and the American Community Survey: What Data Users Need to Know

Geography plays an important role in all U.S. Census Bureau activities by providing the framework used to collect and publish data, including American Community Survey (ACS) estimates. Data users employ ACS data that are tabulated for a variety of geographic areas to produce detailed portraits and maps of social, economic, housing, and demographic characteristics of America’s communities.

This guide provides an overview of geographic areas for which ACS data are available, special considerations in working with spatial data, and links to tools and other resources that data users can use to map ACS data.
