Public-Use Microdata Samples (PUMS)

These files contain records for a sample of housing units with information on the characteristics of each unit and each person in it. While preserving confidentiality (by removing identifiers), these microdata files permit users with special data needs to prepare virtually any tabulation.

PUMS files are available from the American Community Survey and the Decennial Census. Additional microdata files are available from other surveys. See the individual listings under Subjects A-Z on the Census Bureau’s home page, or contact Customer Services on 301-763-INFO (4636).
