Subject: U.S. Census Bureau Releases New 2021 American Community Survey (ACS) 1-Year PUMS and ACS 1-Year Supplemental Estimates



Update from American Community Survey Data Users Group Mary Ana McKay 2021 ACS 1-Year Public Use Microdata Sample (PUMS) Files  We are pleased to announce the release of the 2021 American Community Survey (ACS) 1-year Public Use Microdata Sample (PUMS) files. The PUMS files show the full range of population and housing unit responses collected on individual ACS questionnaires for a subsample of ACS housing units and group quarters persons (approximately one percent of the United States population), with disclosure protection enabled so that individuals or housing units cannot be identified.  The PUMS files allow data users to conduct a custom analysis. Working with PUMS data generally involves downloading large datasets onto a local computer and analyzing the data using statistical software such as R, SPSS, Stata, or SAS.  PUMS data are currently accessible via the ACS website, and the FTP site, and the microdata analysis tool on data.census.gov. Data.census.gov is particularly useful for researchers who need quick statistics with PUMS.   For more information about the PUMS files, visit the links below: Creating Custom Tables Using the American Community Survey Public Use Microdata Sample:  Review this previously recorded webinar to learn more about creating custom tables using the PUMS files PUMS Documentation: Need to find out more about using the PUMS? Our technical documentation includes a User Guide, Data Dictionary, Code and Subject Lists, and other documents to assist users in accessing and using PUMS data PUMS Handbook: This guide provides an overview of the ACS PUMS files and how they can be used to access data about America’s communities. 2021 ACS 1-Year Supplemental Estimates  We are also pleased to announce the release of the 2021 ACS 1-year Supplemental Estimates. Supplemental Estimates are simplified versions of popular ACS tables for geographic areas with at least 20,000 people, compared to the 65,000 population minimum for the standard ACS 1-year estimates.  Visit the Census Bureau's data.census.gov or use the Census API to start exploring these estimates.
