2022 ACS 1-Year Public Use Microdata Sample (PUMS) Files 

We are pleased to announce the release of the 2022 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, 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:

• 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.

2022 ACS 1-Year Supplemental Estimates 

We are also pleased to announce the release of the 2022 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.

2017-2021 ACS 5-Year Selected Population Tables and American Indian and Alaska Native Tables  

We are pleased to announce the release of new American Community Survey (ACS) estimates for detailed race, Hispanic origin, ancestry, and tribal population groups.

Estimates from today's release provide these characteristics for detailed population groups using lower minimum population requirements compared to the standard ACS 1-year release. Highlights include:

• SPTs: Provide estimates for 399 race, Hispanic origin, ancestry, and tribal population groups at numerous geographic areas, including census tracts.
• AIANTs: Provide estimates for 1,059 detailed tribal groups at numerous geographic areas, including Alaska Native Regional Corporations and American Indian and Alaska Native Areas.

Data and Additional Documentation Released

2017-2021 ACS 5-Year Public Use Microdata Sample (PUMS)

We are pleased to announce the release of the 2017-2021 American Community Survey (ACS) 5-year Public Use Microdata Sample (PUMS) files.

The ACS 5-year 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 five percent of the United States population) with disclosure protection enabled so that individuals or housing units cannot be identified.

PUMS files allow data users to create custom estimates and tables that are not available through ACS pretabulated data products. Working with PUMS data generally involves downloading large datasets onto a local computer and analyzing them using statistical software such as R, SPSS, Stata, or SAS.

PUMS data can be accessed via data.census.gov and the Census Bureau's FTP site. 

Visit our Microdata section on the ACS website to find all resources related to PUMS files.  This section contains access to PUMS data, the PUMS Handbook, How-to instructions, FAQs, and PUMS documentation.

The PUMS Documentation page is updated with the 2021 release to include the PUMS ReadMe, Accuracy of the PUMS, PUMS Estimates for User Verification, Subjects in the PUMS, and Data Dictionary. Code Lists have also been posted to help users with the release of the 2017-2021 ACS 5-year PUMS files.

2017-2021 ACS 5-Year Variance Replicate Estimate Tables

We are pleased to announce the release of the 2017-2021 ACS 5-year Variance Replicate Estimate Tables.

These tables allow advanced users to calculate margins of error (MOEs) when collapsing data within a table or across geographies. This method provides a more accurate MOE than available approximation formulas.  

To access these estimates, visit the Variance Replicate Estimate Tables page or through the Census Bureau's FTP site. This page also includes technical documentation, a table and geography list, and table shells.
