GEO1_GN identifies the household's prefecture within Guinea in all sample years. Prefectures are the first level administrative units of the country. GEO1_GN is spatially harmonized to account for political boundary changes across census years. Some detail is lost in harmonization; see the comparability discussion. A GIS map (in shapefile format), corresponding to GEO1_GN can be downloaded from the GIS Boundary files page in the IPUMS International web site.

The full set of geography variables for Guinea 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.
