A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line. The chart is named for the Pareto principle , which, in turn, derives its name from Vilfredo Pareto , a noted Italian economist.
Pareto principle. The Pareto principle may apply to fundraising, i.e. 20% of the donors contributing towards 80% of the total. The Pareto principle (also known as the 80/20 rule, the law of the vital few and the principle of factor sparsity[1][2]) states that for many outcomes, roughly 80% of consequences come from 20% of causes (the "vital few").
Vilfredo Federico Damaso Pareto[4][a] (born Wilfried Fritz Pareto; [7] 15 July 1848 – 19 August 1923) was an Italian polymath, whose areas of interest included sociology, civil engineering, economics, political science, and philosophy. He made several important contributions to economics, particularly in the study of income distribution and ...
The circulation of elites is a theory of regime change described by Italian sociologist Vilfredo Pareto (1848–1923). Changes of regime, revolutions, and so on occur not when rulers are overthrown from below, but when one elite replaces another. The role of ordinary people in such transformation is not that of initiators or principal actors ...

It is not a specialized area of sociology. Instead, it deals with broad fundamental questions about the extent and limits of social influences on individuals ...
The Pareto distribution, named after the Italian civil engineer, economist, and sociologist Vilfredo Pareto, [2] is a power-law probability distribution that is used in description of social, quality control, scientific, geophysical, actuarial, and many other types of observable phenomena; the principle originally applied to describing the distribution of wealth in a society, fitting the trend ...
Pareto efficiency is mathematically represented when there is no other strategy profile s' such that ui (s') ≥ ui (s) for every player i and uj (s') > uj (s) for some player j. In this equation s represents the strategy profile, u represents the utility or benefit, and j represents the player. [6]
t. e. In welfare economics and social choice theory, a social welfare function —also called a social ordering, ranking, utility, or choice function —is a function that ranks a set of social states by their desirability. A social welfare function may yield several possible outcomes; each person's preferences are combined in some way to ...
