Description

GEO1_NG identifies the household's state within Nigeria in all sample years. States are the first level administrative units of the country. GEO1_NG is spatially harmonized to account for political boundary changes across census years; see the comparability discussion. A GIS map (in shapefile format), corresponding to GEO1_NG can be downloaded from the GIS Boundary files page in the IPUMS International web site.

The full set of geography variables for Nigeria 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

There are no changes in administrative boundaries between 2006 and 2010. The only boundary change that occurred in 2006 is the transfer of Bakassi Peninsula from Cross River state to the country of Cameroon. The changes are not reflected in the data, since the peninsula is not a part of Nigeria in the 2006 household survey.
