2020 American Community Survey 1-Year Experimental Data Release

Due to the impact of the COVID-19 pandemic on data collection, the Census Bureau released experimental estimates and products from the 1-year American Community Survey data instead of the traditional 1-year estimates. For more information, visit the 2020 ACS 1-Year Experimental Data Release page.


A limited number of experimental data tables are available for the nation, states, and the District of Columbia. The data will not be available on data.census.gov.
