American Community Survey 1-Year Supplemental Data (2014 - 2021)

American Community Survey Supplemental Data

The American Community Survey (ACS) is an ongoing survey that provides data every year -- giving communities the current information they need to plan investments and services. The ACS covers a broad range of topics about social, economic, demographic, and housing characteristics of the U.S. population.

The supplemental estimates consist of high-level detailed tables tabulated on the 1-year microdata for geographies with populations of 20,000 or more.  The intention of this product is to allow people with smaller populations key estimates that are more current than the 5-Year file.

These high-level estimates are available for the nation, all 50 states, the District of Columbia, Puerto Rico, every congressional district, every metropolitan area, and all counties and places with populations of 20,000 or more.
