American Community Survey (ACS) data are tabulated for a variety of different geographic areas ranging in size from broad geographic regions to cities, towns, county subdivisions, and block groups. View the chart below outlining the number of areas receiving data by geographic level. Note that 5-year estimates are available for all areas.
The chart below includes only selected summary levels, therefore not all geographic areas are represented below. To view the complete list of geographic areas published for ACS 1-year and 5-year estimates, as well as detailed lists for 1-year and 1-year Supplemental Estimates, visit the Reference Materials page.
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.
Update for the 2020 American Community Survey
Due to the impact of the COVID-19 pandemic, the Census Bureau changed the 2020 American Community Survey (ACS) release. Instead of providing the standard 1-year data products, including the 1-year Supplemental Estimates, the Census Bureau released experimental estimates from the 1-year data. This includes a limited number of data tables for the nation, state, and the District of Columbia. Puerto Rico is not included.
