1. Poverty and Income Distribution
There are two common indicators of the level of poverty and inequality in a society: the poverty rate and the Gini coefficient. The former is defined as the share of persons with a disposable income below a certain percentage of national median disposable income. The latter is a measure of inequality that lies between 0 and 1. A higher Gini coefficient indicates a higher level of inequality in a society.
