# Rank Size Rule And Primate Cities

```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
