American Community Survey (ACS)

ACS 1-year (and previous 3-year) data are published for a selection of geographies based on population size. The specific geographic areas that have published data are listed in the Excel files below. From 2005 through 2014, maps were created to show the counties and places, and American Indian Areas (AIAs) / Alaska Native Areas (ANVSAs and ANRCs) that received published data yearly in these datasets. These maps are no longer being created and users are advised to refer to the detailed list of geographic areas for ACS 1-year estimates [<1.0 MB] and ACS 1-year Supplemental Estimates [<1.0 MB] as a text alternative.

ACS 5-year data are tabulated for all counties, places, AIAs, ANVSAs and ANRCs, so no reference maps were produced.
