Definition
GEO_ZW1999 (V101_ZW1999) indicates the region of Zimbabwe where the respondent was interviewed. DHS regions in the 1999 Zimbabwe survey are equivalent to provinces.
Other sample years have their own sample-specific geography variables. There is also an integrated variable GEO_ZW1994_2015, that provides spatially consistent units over time.
