Definition
GEO1_AT identifies the household's state within Austria in all sample years. States are the first level administrative units of the country. GEO1_AT is spatially harmonized to account for political boundary changes across census years. Some detail is lost in harmonization. A GIS map (in shapefile format), corresponding to GEO1_AT can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Austria 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.
