Public Use Microdata Areas (PUMAs) provide most detailed U.S. wall-to-wall geography (2,378 areas) for which current year demographic-economic data are available and annually updated. Use the related Public Use Microdata Sample (PUMS) data to develop custom-defined subject matter estimates for one or all PUMAs.

PUMA Microdata

Public Use Microdata Sample (PUMS) files provide a way to develop custom estimates of demographic summary statistics for PUMAs, states and the U.S. The American Community Survey (ACS) PUMS files are comprised of samples of individual respondent person and housing unit records. The ACS PUMS files are released annually providing a means to develop similar custom estimates with annual updates.
