Rank Size Rule And Primate Cities AP HUG

Objective To understand what the Rank Size Rule is and the pattern that it tries to outline

Rank Size Rule This is an attempt to find a numerical relationship between population size of settlements within an area such as a country or county Settlements are ranked in descending order of population size, with the largest city first

Assumptions The 2 nd ranked city will have 1/2 the population of the 1 st The 3 rd ranked city will have 1/3 population of the 1st The 4 th ranked city will have a ¼ population of the 1st ranked city

Example The largest city has a population of 1,000,000 The 2 nd largest city: 1,000,000/2= 500,000 The 3 rd city: 1,000,000/3= 333,333 The 4 th city: 1,000,000/4= 250,000 And so on….

Formula This allows us to express the rank size rule as: Pn= Pl /n (or R) Pn= The population of the City Pl= The population of the largest city N (or R)= The rank size of the city

Primate City This is found where the largest city (often the capital) completely dominates a country or region The population size will be many times greater than that of the 2 nd or 3 rd city

Example of Primate City: Buenos Aires, Argentina Populations in thousands: Buenos Aires: 10,990 Cordoba: 1198 Rosario: 1096 Mendoza: 775 La Plata: 640 San Miguel de Tucuman: 622 Other Primate Cities in outside Argentina include Mexico City and Lima

Binary Distribution Occurs where there are 2 very large cities of almost equal size within the same country. One may be the capital and the other a major port or industrial centre Examples: Spain- Barcelona and Madrid

Exceptions to the rule Rank size rule is more likely to operate in a country that is developed or urbanized for a long time and is: – Large in size – Stable economic and political organisation Primate distribution is likely to occur in countries that are small, less developed and only recently urbanised
