-- 2,378 statistical areas covering the U.S. and outlying areas -- developing and using custom demographic estimates -- expanding insights through data analytics August 2022 .. .. the 2020 American Community Survey (ACS) 5-year PUMS (Public Use Microdata Sample) data were released March 31, 2022. See more about the ACS 2020 5-year PUMS here. Public Use Microdata Areas (PUMAs) are used as a tabulation area for PUMS estimates. 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. 2020 PUMAs
This subsection is about the 2020 PUMAs which were
defined/released in August 2022. There will be a new PUMA 2020 page in the near future.
In general, there is close geographic correspondence between the 2010 and 2020 PUMA vintages, but with many exceptions.
It matters if the boundaries differ as this limits the ability to perform 2010-2020 demographic change analysis.
The PUMA 2010 count for all states is 2,351 and the PUMA 2020 count is 2,461.
The U.S. national scope 2010 and 2020 PUMAs are now available in the VDA Web GIS MetroDynamics GIS project. See details here about using VDA/MatroDynamice with PUMAs integrated with other geography/subject matter The following graphic illustrates PUMA 2020 boundaries in the Los Angeles County area. There are 69 2010 PUMAs and 71 2020 PUMAs comprising Los Angeles County.

PUMA Vintages ACS 5-year PUMS files are released annually. The ACS 2020 5-year PUMS files use the 2010 vintage PUMAs. The 2010 PUMAs apply generally throughout the 2010s. The ACS 2016 PUMS files were the first to use all 2010 PUMAs for each year of the PUMS data. The ACS 2020 PUMS data (release date March 31, 2022) use the 2010 vintage PUMAs. As will the ACS 2021 PUMS data (early 2023). The 2020 vintage PUMAs (boundaries, codes, names) are expected to be completed in mid-2022. These geographies are expected to be included in TIGER line files released in 2023. The 2020 PUMAs will be used with the ACS 2022 PUMS files (released early 2024). PUMS Data are Estimated for PUMAs; Using VDA Web GIS The following graphic illustrates how you can use VDA Web GIS to view Public Use Microdata Areas (PUMAs) contextually relative to topography or other geostatistical data. The static map views in the scoll section at right are essentially obsoleted with availability of VDA Web GIS. In the following example the Find Address feature is used to zoom to downtown Los Angeles and show PUMA boundaries and codes. An arbitrary PUMA is clicked to show the demographic profile for that PUMA (crosshatched). This view illustrates using the VDA Table where each row corresponds to a PUMA. In this example, total population and median household income are displayed as selected columns; the table is sorted in descending order on median household income.

PUMA Summary Statistic Data .. goto top 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 PUMS Microdata for PUMAs .. goto top 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. • ACS 2017 1-Year PUMS Data by PUMA • ACS 2017 5-Year PUMS Data by PUMA 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.
