Codes and Frequencies
GEO_NG2003 (V101_NG2003) indicates the region of Nigeria where the respondent was interviewed. DHS regions in the 2003 Nigeria survey are equivalent to grouped states.
Other sample years have their own sample-specific geography variables. There are also integrated variables, GEO_NG2003_2018 and GEOALT_NG2008_2018, that provide spatially consistent units over time. The 2003 Nigeria sample is excluded from GEOALT_NG2008_2018 due to inconsistent boundaries.
A GIS map for GEO_NG2003 (in shapefile format) can be downloaded from the DHS Program Spatial Data Repository Boundaries page.
