Statistics - Pareto ( Principle | Distribution )

1 - About

the Pareto principle or the “80-20 rule” corresponds to a Pareto probability distribution with shape log(5)/log(4) = 1.161.

See also: The 1 Percent Rule

Pareto originally used this distribution to describe the allocation of wealth among individuals since it seemed to show rather well the way that a larger portion of the wealth of any society is owned by a smaller percentage of the people in that society. ie 20% of the population controls 80% of the wealth.
