Description
Definition
GEO2ALT_US identifies the most detailed areas that can be consistently delineated from the geographic codes available in United States PUMS (Public Use Microdata Series) files from 1980 to 2010. In 1980 PUMS files, the smallest identified units are “county groups,” and in later PUMS files, the smallest identified units are Public Use Microdata Areas (PUMAs). All of these units nest within states, but the definitions of PUMAs differ from county groups, and the 1990 PUMAs differ from the 2000 PUMAs (which are used for 2000, 2005 and 2010 samples). GEO2ALT_US is spatially harmonized to account for these boundary changes. Each GEO2ALT_US code corresponds to a distinct set of 1980 county groups and 1990 and 2000 PUMAs that collectively cover a consistent geographic area across time. More details on construction of PUMAs can be found in IPUMS USA website. The following excel file lists GEO2ALT_US and their relationship to CONSPUMA.
A separate variable, GEO2_US, identifies sets of 2000 and 2010 PUMAs that comprise comparable populations for samples from 2000 forward. GEO2_US corresponds with CPUMA0010 variable in IPUMS USA .
Some detail is lost in harmonization; see the comparability discussion. A GIS map (in shapefile format), corresponding to GEO2ALT_US can be downloaded from the GIS Boundary files page in the IPUMS International web site. The GIS boundary files for GEO2ALT_US are based on the U.S. Census Bureau’s 2000 TIGER/Line files.
The full set of geography variables for the United States can be found in the IPUMS International Geography variables list. For cross-national geographic analysis on the first and second major administrative level refer to GEOLEV1, and GEOLEV2. More information on IPUMS-International geography can be found here.
