Definition
GEO_KE1989 (V101_KE1989) indicates the region of Kenya where the respondent was interviewed. DHS regions in the 1989 Kenya survey are equivalent to provinces.
Other sample years have their own sample-specific geography variables. There is also an integrated variable, GEO_KE1989_2014, that provides spatially consistent units over time.
A GIS map for GEO_KE1989 (in shapefile format) can be downloaded from the DHS Program Spatial Data Repository [URL omitted from DDI.] Boundaries page.
