PUMS Data

The American Community Survey (ACS) Public Use Microdata Sample (PUMS) files are a set of untabulated records about individual people or housing units. Supporting documentation for the data below is available on the PUMS Documentation page. To learn more, visit our PUMS Handbook.

PUMS files are available on the File Transfer Protocol (FTP) site in both CSV and SAS formats. Both formats contain two record types including housing files (e.g. "csv_hak" or "sas_hak") or person files (e.g. "csv_pak" or "sas_pak").  Microdata access from 2005-current is available on data.census.gov.
