Codes and Frequencies
Most IPUMS data transformations are performed using variable harmonization tables that specify how each value in the source data is recoded. Some variables also require programming logic in addition to the harmonization table. The harmonization documents for this variable are:
GEO2_GN identifies the household's sub-prefecture within Guinea from 1996 to present. Sub-prefectures are the second level administrative units of the country, after prefectures. A GIS map (in shapefile format), corresponding to GEO2_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.
Comparability — General
The 1983 sample is not included in GEO2_GN because the location of several sub-prefectures could not be determined.
Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time. Where officially-defined sub-prefectures have populations less than 20,000, they have been regionalized (combined) with neighboring sub-prefectures.
Boundary changes for GEO2_GN are too numerous to list here, but users should be aware that there were changes over time.
