selection of sample households was based on two mutually exclusive
sampling frames for the rural and urban areas. Household counts for
the 2005 Population and Housing Census of Bhutan (PHCB 2005) at the
village level, updated after more recent listing activities, were used in
constructing the sampling frame of primary sampling units (PSUs) for
rural areas.Urban block counts from PHCB 2005, whichwere greatly supplemented
by the National Statistical Bureau's (NSB) household listing
operations in the most densely populated urban areas in December
2011–February 2012, were used as the basis for the sampling frame of
PSUs for the urban areas.
