Composition of PUMAs and Super-PUMAs in the 2000 census and ACS/PRCS from 2005-present
PUMAs are the lowest level of geography in the 2000 5% census sample and the ACS/PRCS samples from 2005 onwards. Super-PUMAs are the lowest level of geography in the 2000 1% sample. PUMAs are nested within SuperPUMAs; each Super-PUMA is comprised of anywhere from two to six PUMAs.
The tables below show the detailed composition of each PUMA, as well as showing which PUMAs comprise each Super-PUMA. For users who want to analyze these tables in a statistics package, PUMA and Super-PUMA composition information from all states is available as one downloadable ASCII file. The PUMA boundaries in the ACS/PRCS are identical to those in the 2000 5% census sample.
Boundary files for PUMAs and SuperPUMAs
Two sets of nationwide boundary files are available for download in .zip format. The PUMA boundaries in the ACS/PRCS are identical to those in the 2000 5% census sample.
