The Pareto distribution is a probability model for continuous variables. It looks like a ski slope. The Pareto distribution is commonly used with socio-economic and other naturally occuring quantities that are distributed in a ski slope manner with very long right tails. The long right tails describe inequality, the possibility of a few extremely large outcomes. The distribution appears to be primarily used in the business and economics fields, but also within political science. The Pareto distribution works best in situations when we want to understand the long right tails. The discrete counterpart of the Pareto distribution is Zipf’s law, which is sometimes refered to as the zeta distribution.
