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

Directions

• Independently: read Ch 13 H 294-295 in your books and complete a Concepts and Notes Sheet

• Independently: Review the Notes Section of these PPT slides to review what you have read in the book.

• Independently or in Partners: Complete the practice slides found in this packet.

NOTES SLIDES

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 2nd ranked city will have 1/2 the population of the 1st

• The 3rd ranked city will have 1/3 population of the 1st

• The 4th ranked city will have a ¼ population of the 1st ranked city

Example

• The largest city has a population of 1,000,000• The 2nd largest city: 1,000,000/2= 500,000• The 3rd city: 1,000,000/3= 333,333• The 4th 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 2nd or 3rd 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

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
