Small Area Estimates of Poverty and Inequality by municipality, Bangladesh, 2008

The Global Poverty Mapping Project seeks to enhance current understanding of the global distribution of poverty and the geographic and biophysical conditions of where the poor live. Additionally, the project aims to assist policy makers, development agencies, and the poor themselves in designing interventions to reduce poverty.

The Small Area Estimates of Poverty and Inequality dataset consists of consumption-based poverty, inequality and related measures for subnational administrative units in approximately twenty countries throughout Africa, Asia, Europe, North America, and South America. These measures are derived on a country-level basis from a combination of census and survey data using small area estimates techniques. The collection of data have been compiled, integrated and standardized from the original data providers into a unified spatially referenced and globally consistent dataset. The data products include shapefiles (vector data), tabular datasets (csv format), and centroids (csv file with latitude and longitude of a geographic unit and associated poverty estimates). Additionally, a data catalog (xls format) containing detailed information and documentation is provided. This dataset is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with a number of external data providers.

Attributes Range Median Mean Standard Deviation
The Squared Poverty Gap Index -1.00 - 0.11 0.04 0.04 0.05

The Squared Poverty Gap Index: measures of the severity of poverty for each area. By squaring the poverty gap for each individual/household, this measure gives greater weight to those observations that fall far below the poverty line than those that are closer to it.

The FGT (Foster, Greer, Thorbecke) measures are a family of poverty measures where α is a measure of the sensitivity of the index to poverty, the poverty line is (z), and (Gn) is equal to the poverty line (z) less actual income (Yi) for poor individuals. When α is set equal to 0, P(0) is simply the headcount index. When α is set equal to 1, P(1) is the poverty gap index, and when α is set equal to 2, P(2) is the severity of poverty or squared poverty gap index.

Standard error of the Headcount Index -1.00 - 0.11 0.04 0.04 0.05

Standard error of the Headcount Index: the proportion of the population that is counted as poor. It is often denoted by P(0), where N is the total population, and I (.) is an indicator function that takes on a value of 1 if the bracketed expression is true, and 0 otherwise. So if expenditure (Yi) is less than the poverty line (z) then I(.) equals to 1 and the individual would be counted as poor. Np is the total number of poor.

When α is set equal to 0, P(0) is simply the headcount index. When α is set equal to 1, P(1) is the poverty gap index, and when α is set equal to 2, P(2) is the severity of poverty or squared poverty gap index.

Standard error of the Poverty Gap Index -1.00 - 0.05 0.02 0.01 0.05

Standard error of the Poverty Gap Index: the mean proportionate poverty gap in the population, where the poverty gap (Gn) is the poverty line (z) less actual income (Yi) for poor individuals (the non poor have a zero poverty gap). Some think of this measure as the per capita cost of eliminating poverty (relative to the poverty line), through perfectly targeted transfers to the poor, in the absence of transactions costs and disincentive effects.
