1. REVISITING SOME CONCEPTS FROM BEFORE

2.  Write down everything that you remember about the following concepts:  Central Place Theory  Basic vs. nonbasic industries  Rank-size rule  Primate cities  World cities  Now, discuss with your group and look back through the book/notes before we go over these concepts as a class ON YOUR OWN…

3.  Explains relationships between cities and surrounding communities and how the most profitable location of a service can be identified  Based on demands for goods and services  Economic hubs = large cities  Central place – market center for the exchange of goods and services by people attracted from the surrounding area  Market Area/Hinterland – the area surrounding a service from which customers are attracted  Range – maximum distance people are willing to travel to use a service  Threshold – minimum number of people needed to support the service CENTRAL PLACE THEORY: WALTER CHRISTALLER

4.  1) Surface of ideal region would be flat and have no physical barriers  2) Soil fertility would be the same everywhere  3) population and purchasing power would be evenly distributed  4) Region would have a uniform transportation network to permit direct travel from each settlement to the other  5) From any given place, a good or service could be sold in all directions out to a certain distance CENTRAL PLACE THEORY ASSUMPTIONS

5. USING HEXAGONS

6.  Market areas are arranged in a regular pattern  Fewer large settlements that are farther apart from each other than small settlements  Neighborhoods within large settlements provide services that have small thresholds and ranges  Market areas across a developed country would be a series of hexagons of various sizes CENTRAL PLACE THEORY

7.  In developed countries, geographers observe that ranking settlements from largest to smallest in population produces a regular pattern  Rank-size rule – the country’s n th largest settlement is 1/n the population of the largest settlement  Countries that do not follow the rank-size rule may follow the primate city rule  The largest settlement has more than twice as many people as the second- ranking settlement  Largest city - primate city  Mexico City – primate city  Guadalajara - 2 nd largest country, 5 times smaller than Mexico City  Rank-size rule indicates that society is sufficiently wealthy to justify the provision of goods and services to consumers throughout the country  Absence of rule indicates a hardship for people who must travel long distances to reach an urban settlement with shops and services RANK-SIZE RULE

8.  Which unit do you think these concepts should be covered in?  Industry/Services  Urbanization  Why? DISCUSSION
