Accessing 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 on the File Transfer Protocol (FTP) site are available in CSV and SAS formats. PUMS data prior to 2005 can also be found on our FTP site. Microdata access from 2005-current is available on data.census.gov.
