American Community Survey data are tabulated for a variety of different geographic areas ranging in size from broad geographic regions to cities, towns, neighborhoods, and census block groups. See the chart below outlining the number of areas receiving data by geographic level. Note that 5-year estimates are available for all areas.

Or download detailed lists of geographic areas for 1-year estimates [XLSX - <1.0 MB].

Many factors other than population size also affect whether ACS data are published. Visit the Data Suppression page for more details and to learn how population thresholds are applied.
