Definition
GEO_ZM2001 (V101_ZM2001) indicates the region of Zambia where the respondent was interviewed. DHS regions in the 2001 Zambia survey are equivalent to provinces.
Other sample years have their own sample-specific geography variables. There is also an integrated variable GEO_ZM1992_2013, that provides spatially consistent units over time.
