Definition Gini ratio is the ratio of the area between the Lorenz curve and the diagonal (the line of perfect equality) to the area below the diagonal. It is a measure of the extent to which the distribution of income/ expenditure among families/individuals deviates from a perfectly equal distribution, with limits 0 for perfect equality and 1 for perfect inequality.
P10/P90 is the ratio of income of families in the bottom 10% to the upper 10% of families.
Income share of bottom 30% to total income (%) is the total income of families/individuals in the bottom 30th percentile divided by the total income of all families/individuals.
Income share of bottom 10% to total income (%) is the total income of families/individuals in the bottom 10th percentile divided by the total income of all families/individuals.
Method of Computation Gini ratio is the ratio of the area between the Lorenz curve and the diagonal (the line of perfect equality) to the area below the diagonal.
P10/P90 = (Income of families in the bottom 10%) / (Income of families in the upper 10%)
Income Share of Bottom 30% to Total Income (%) = (Total income of families/individuals in the bottom 30th percentile) / (Total income of all families/individuals)
Income Share of Bottom 10% to Total Income (%) = (Total income of families/individuals in the bottom 10th percentile) / (Total income of all families/individuals)
