Where are cities located and why?
in a model urban hierarchy, the population of the city or town will be inversely proportional to its rank in the hierarchy. (sometimes referred to as the nth rule)
largest city = 12 million = n/1
2nd largest = 6 million = n/2
3rd largest = 4 million =n/3
4th largest = 3 million =n/4
The leading city of a country. The city is disproportionately larger than the rest of the cities in the country.
For example: London, UK
Mexico City, Mexico
- the rank-size rule does not work for a
country with a primate city
Walter Christallerdeveloped a model to predict how and where central places in the urban hierarchy (hamlets, villages, towns, and cities) would be functionally and spatially distributed.
Assumed: 1. surface is flat with no physical barriers
2. soil fertility is the same everywhere
3. population and purchasing power are evenly distributed
4. region has uniform transportation network
from any given place, a good or service could be sold in all directions out to a certain distance
C = city
T = town
V = village
H = hamlet
