Lorenz curve

The Lorenz curve is a graphical tool used to show how evenly or unevenly income or wealth is distributed within a population. It plots the cumulative percentage of total income earned against the cumulative percentage of the population, starting from the poorest to the richest. If income were perfectly evenly distributed, the Lorenz curve would be a straight diagonal line. The more the curve bows away from this line, the greater the inequality. It helps illustrate disparities and assess how wealth is shared across a society.
