ab: Summary: The Gini index is a summary statistic that measures how equitably
a resource is distributed in a population; income is a primary example.
In addition to a self-contained presentation of the Gini index, we give
two equivalent ways to interpret this summary statistic: first in terms
of the percentile level of the person who earns the average dollar, and
second in terms of how the lower of two randomly chosen incomes
compares, on average, to mean income.
