U.S. Census Bureau Releases New 2023 American Community Survey (ACS) 1-Year PUMS and ACS 1-Year Supplemental Estimates

2023 ACS 1-Year Public Use Microdata Sample (PUMS) Files 

We are pleased to announce the release of the 2023 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.

2023 ACS 1-Year Supplemental Estimates 

We are also pleased to announce the release of the 2023 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.

Did you know that the ACS has an online Data Users Group with over 5,500 members? The purpose of the ACS Data Users Group is to improve understanding of the value and utility of ACS data, as well as promote information sharing among data users about key ACS data issues and applications.

The website contains information, such as previous conference presentations and archived webinars and the discussion forum allows members to share messages, materials, and announcements related to the ACS. Census Bureau staff are also members and share program updates here.

Membership is free and open to all interested ACS data users.
