U.S. Census Bureau Releases 2015-2019 ACS 5-Year PUMS File and Variance Replicate Estimate Tables

January 14, 2021

2015-2019 ACS 5-Year Public Use Microdata Sample (PUMS)

We are pleased to announce the release of the 2015-2019 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).

PUMS files allow data users to conduct a custom analysis, though the files also tend to be more complicated to use. 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 new 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 Technical Documentation page is updated with the 2019 release to include the PUMS ReadMe, subjects in the PUMS, data dictionary, code lists, Accuracy of the PUMS, and PUMS Estimates for User Verification.

 

2015-2019 ACS 5-Year Variance Replicate Estimate Tables

We are pleased to announce the release of the 2015-2019 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 Tables Data page or through the Census Bureau's FTP site.

The Variance Replicate Tables Documentation page is also updated to include technical documentation, a table and geography list, and table shells.
