What follows the Pareto distribution?
Pareto noticed that approximately 80% of Italy’s land was owned by 20% of the population. He then carried out surveys on a variety of other countries and found to his surprise that a similar distribution applied….In economics.
| Quintile of population | Income |
|---|---|
| Third 20% | 2.30% |
| Fourth 20% | 1.85% |
| Poorest 20% | 1.40% |
How is a Pareto distribution created?
The Pareto distribution (created by the 19th Century Italian economist Vilfredo Pareto) is defined by a shape parameter, α (also called a slope parameter or Pareto Index) and a location parameter, X. It has two main applications: To model the distribution of incomes. To model the distribution of city populations.

Is the Pareto survival function a power law distribution?
The Pareto distribution is a power law distribution. It is a model that can describe phenomena that behave in a log-linear fashion. Let’s revisit the original reasoning for using the Pareto survival function as a model of income. Let be the number of people with income greater than .
How is the Pareto distribution different from Zipf’s law?
The Pareto distribution is a continuous probability distribution. Zipf’s law, also sometimes called the zeta distribution, is a discrete distribution, separating the values into a simple ranking. Both are a simple power law with a negative exponent, scaled so that their cumulative distributions equal 1.
