Definition

A scalar measure of the dispersion of a non‑negative resource (commonly income or wealth) across a population, defined from the Lorenz curve as twice the area between the line of perfect equality and the empirical Lorenz curve; it ranges from 0 (perfect equality) to 1 (maximal concentration) when normalized, and summarizes relative inequality independently of the mean under scale‑invariance.
