RANK SIZE RULE! AND THE LARGEST CITIES IN THE WORLD What is a Primate City?
Pr=P1/r - German geographer – George Zipf Pr is the population of the Urban place of rank r P1 - is the population of the first ranked place r - is the rank (determined by size) Eg. City A has 900 000 people and is the first ranked city in the country. City B which is second to city A will have one-half the population of city A. B = 900 000/2 = 450 000 What would be the population of City C (the third largest)?
