GEO_MW1992 (V101_MW1992) indicates the region of Malawi where the respondent was interviewed. DHS units in the 1992 Malawi survey are equivalent to regions.
Other sample years have their own sample-specific geography variables. There is also an integrated variable, GEO_MW1992_2016, that provides spatially consistent units over time.
