Definition
GEO_ET2011 (V101_ET2011) indicates the region of Ethiopia where the respondent was interviewed. DHS regions in the 2011 Ethiopia survey are equivalent to states.
Other sample years have their own sample-specific geography variables. There is also an integrated variable, GEO_ET2000_2016, that provides spatially consistent units over time.
A GIS map for GEO_ET2011 (in shapefile format) can be downloaded from the DHS Program Spatial Data Repository [URL omitted from DDI.] Boundaries page.
