According to Wikipedia, "In economics, the Lorenz curve is a graphical representation of the cumulative distribution function of the empirical probability distribution of wealth; it is a graph showing the proportion of the distribution assumed by the bottom y% of the values. It is often used to represent income distribution, where it shows for the bottom x% of households, what percentage y% of the total income they have." The graph above features the percentage of the population from the poorer to the richer comparing the wealth. The blue line (Lorenz Curve) represents income distribution.
