| #ZIPF law predicts the size of the world's biggest cities The #city with the largest population in any country is generally twice as large as the next-biggest, and so on. Incredibly, #Zipf #law for cities has held true for every country in the world, for the past century. George Zipf noticed that the number one ranked word was always used twice as often as the second rank word, and three times as often as the third rank. He called this a #rank vs. #frequency rule, and found that it could also be used to describe income distributions in any given country, with the richest person making twice as much money as the next richest, and so forth. &Rob 2015-11-18 10:54:37 |
