   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.

   GINI

   The Gini Coefficient is a measure of inequality and is derived from the "Gini Mean Difference" which is a measure of risk or variability. The Gini coefficient is a measure of the degree to which a population shares the resources unequally. An index of income inequality ranging between 0 (for perfect equality) and 1 (for absolute inequality). It is defined as the ratio of the area between the Lorenz curve (a cumulative frequency curve that compares the distribution of a specific variable with the uniform distribution that represents equality) and the perfect equality line to the area between the lines of perfect equality and perfect inequality.
