Poverty and inequality maps - spatial descriptions of the distribution
of poverty and inequality - are most useful to policy-makers and researchers
when they are finely disaggregated, that is when they want to
represent small geographic units, such as cities, municipalities, districts
or other administrative partitions of a country. In order to produce
poverty and inequality maps, living standard surveys covering income
or consumption are econometrically combined with data from censuses
or other sample surveys large enough to allow disaggregation of the
poverty and inequality estimates.
