Definition
GEO_BD2011 (V101_BD2011) indicates the region of Bangladesh where the respondent was interviewed. DHS regions in the 2011 Bangladesh survey are equivalent to divisions.
Other sample years have their own sample-specific geography variables. There is also an integrated variable, GEO_BD1994_2014, that provides spatially consistent units over time.
