Public Use Microdata Sample (PUMS) Files
  -- developing and using custom demographic estimates
  -- expanding insights through data analytics

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.

See links to detailed PUMA 2010 maps ... lower right scroll section.

PUMA Summary Statistic Data
2010 vintage PUMA summary statistic data, based on the ACS 2012 1-year estimates, may be accessed via these interactive tables:
  • General Demographics
  • Social Characteristics
  • Economic Characteristics
  • Housing Characteristics

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.

2010 Vintage PUMA Geography
The 2,378 2010 vintage PUMAs are developed using Census 2010 geography, cover the U.S. wall-to-wall, conform to state boundaries, and where possible are comprised of whole Census 2010 census tracts. The first use of the 2010 vintage PUMAs is with the ACS 2012 PUMS and 1-year summary statistic data. Use the interactive table in this section to examine 2010 PUMAs and PUMA component area geography.

While PUMS files contain data for respondents across the U.S., most lower level geography are not identified by any variables in the PUMS files. The PUMA is the most detailed unit of geography identified in the PUMS files.

PUMAs are special non-overlapping areas that partition each state into contiguous geographic units containing no fewer than 100,000 people each. 2010 PUMAs were built on census tracts, and cover the entirety of the United States and Puerto Rico.

Mapping PUMAs
What are the PUMA boundaries? How do they relate to other geography? Use the CV XE GeoGateway to view PUMA shapefiles. Zoom into one or a set of PUMAs. Overlay county or other geography. Integrate your PUMS summary statistic estimates into the PUMA shapefiles; display thematic pattern maps of the custom estimates. See New York PUMA applications and more detailed Arizona by PUMA views.
