The U.S. Census Bureau produces a large number of data profiles, tables, maps, and other products based on American Community Survey (ACS) data. Even this abundance of pretabulated estimates and data products cannot meet the needs of every data user. The Census Bureau’s ACS Public Use Microdata Sample (PUMS) files enable data users to create custom estimates and tables, free of charge, that are not available through pretabulated ACS data products.
This guide provides an overview of the ACS PUMS files and how they can be used to access data about America’s communities.
