The 80/20 Principle

The “Pareto” principle also known as the 80/20 rule, the law of the vital few, or the principle of factor sparsity states that, for many events, roughly 80% of the effects come from 20% of the causes.

Management consultant Joseph M. Juran suggested the principle and named it after Italian economist Vilfredo Pareto, who noted the 80/20 connection while at the University of Lausanne in 1896, as published in his first work, Cours d'économie politique. Essentially, Pareto showed that approximately 80% of the land in Italy was owned by 20% of the population.
