He also used it to describe distribution of income. Note that the Pareto distribution is not realistic for wealth for the lower end. This distribution is not limited to describing wealth or income, but to many situations in which an equilibrium is found in the distribution of the “small” to the “large”.

Pareto distribution is applied to extreme events such as annually maximum one-day rainfalls and river discharges. The last expression is the cumulative distribution function of an exponential distribution with rate α. Pareto distributions are continuous probability distributions. This does not apply only to income, but also to wealth, or to anything else that can be modeled by this distribution.

1, which, as noted above, have infinite expected value, and so cannot reasonably model income distribution. Lorenz curves for a number of Pareto distributions. Examples of the Lorenz curve for a number of Pareto distributions are shown in the graph on the right. 62 people have as much wealth as the poorest half of the world’s population. We can estimate the Pareto index that would apply to this situation. The solution is that α equals about 1. Lorenz plot on the right.

Specifically, the Gini coefficient is twice the area between the Lorenz curve and the equidistribution line. As in the standard Pareto distribution α determines the shape.
