It shows inequality in income
distribution. Inequality indices can also be
derived directly from the Lorenz curve. Perhaps
the most commonly-used inequality index is the
Gini coefficient, which ranges from 0 (perfect
equality) to 1 (perfect inequality). It is the ratio
of the area enclosed by the Lorenz curve and the
perfect equality line to the total area below that
line.
