Who drew the first Pareto Chart?
Joseph Juran (quality expert) named the Pareto Chart after Vilfredo Pareto (pictured below).
Who was Vilfredo? An economist, sociologist, and engineer born in 1848. He discovery that 80 percent of the land (or wealth) in Italy was held by 20% of the population. However, Vilfredo never drew a Pareto Chart.
When was the first Pareto Chart drawn? I would suggest that graphics expert William Playfair (pictured above) drew the first approximation of a Pareto Chart (or bar chart) soon after 1781. BEFORE Vilfredo Pareto was even born! The chart is shown above.
What do you think? Does the graph of imports and exports to Scotland look like a Pareto Chart? Maybe we should call them the Playfair Charts?
