Entry ID: CIESIN_SEDAC_ACRP_1990_PBF

[ Update this Record ]

Summary
Abstract: The 1990 Public Use Microdata Sample Areas (PUMA) Boundary Files portion of the Archive of Census Related Products (ACRP) consists of 5% sample (apuma)

and 1% sample (bpuma) areas for the mapping of 1990 PUMS data covering the continental United States, Alaska, and Hawaii. These boundary files are created based on equivalency files

generated by the Geographic Correspondence Engine (GeoCorr). A national census tract to PUMA geography correspondence file is used in merging the two files resulting in the PUMA

geographies. An additional file is also available consisting of geographic centroids for the PUMA coverages calculated by UIC (Urban Information Center/Office of Computing, University of

Missouri). This portion of the ACRP is produced by the Columbia University Center for International Earth Science Information Network (CIESIN).


Purpose: To provide an authoritative boundary layer for the geographies associated with the Public Use Micro Sample (PUMS) data files.
