Inequality level

The Lorenz curve plots the cumulative share of income against the cumulative share of population, from poorest to richest. Perfect equality is the diagonal; the more the curve bows below it, the more unequal the distribution. The Gini coefficient is twice the area between them — 0 is total equality, 1 is one person owning everything.

Governing equation

G = 1 - 2 \int_{0}^{1} L (p) d p = \frac{A}{A + B} = 0.628

Reading this result: High inequality (Gini 0.628): the curve bows far under the diagonal and the richest 10% capture 37% of all income.
