1. Models of Urban Distribution and Location

2. Rank-Size Rule Ideal urban system Population of a city is inversely proportional to its rank in the hierarchy 1/R x Population of Largest City R = rank

5. Rank-Size Rule Seems to hold true for mature urban systems (like the United States) Does not hold true for many developing countries –Primate city

6. What about location? How far would you be willing to travel for… A bagel? A rock concert?

7. Central Place Theory Walter Christaller (1933) How would cities (market centers) be distributed in the ideal? Assumptions –Featureless (isotropic) plain –Evenly distributed population/resources –Consumers have similar means/tastes

8. Central Place Theory Hierarchy of goods –Range of a good How far one is willing to travel –Threshold of a good How much population you need to support production

9. Central Place Theory The larger the center, the fewer in the system Centers distinguished by goods available there –Orders of goods

10. Central Place Theory The highest order center will provide all goods in the system Lower orders only certain goods So what is the best way to represent the distribution of market centers.

15. k=7 Administrative Principle
