Definition
GEO2_SN identifies the household's department within Senegal in all sample years. Departments are the second level administrative units of the country, after regions. GEO2_SN 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 GEO2_SN can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Senegal 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.
