1 Ch. 13: Urban Patterns Key Issue 1

2 Urbanization Urbanization-the process by which the population of cities grows. Increasing percentage of people in cites 1800 = 3% 1850 = 6% 1900 = 14% 1950 = 30% 2000 = 47% 2008 = 51% ¾ of MDCs, 2/5 of LDCs-- why? MDCs are now “fully urbanized” Percentage living in cities has greatly increased in LDCs Urbanization is: The number of ppl in cities The percentage of ppl in cities The land area occupied by cities

3 Urbanization Increasing number of people in cities
MDCs have a higher percent of urban residents, but LDCs have more of the very large urban settlements (8 out of 10) Growth of cities used to be tied to Industrialization In LDCs, big cities are not connected to an increased in development levels Urbanized Area: city plus continuous suburbs The Industrial Revolution promoted urbanization in MDCs

4 2015 World’s Largest Cities

5 Urban Settlements are difficult to define…
Social differences: Louis Wirth: Large size Different social relationships High population density Specialization and competition Socially heterogeneous people Diversity and loneliness Physical differences: Legal boundary Self governing, taxes Continuously built up >1000 people/mile Functional area Area of influence May be beyond legal boundaries TV stations, newspapers, sports teams

6 Overlapping Metropolitan Areas
Megalopolis—adjacent, overlapping Metropolitan Statistical Areas Boswash Great Lakes area Southern California German Ruhr Japan Tokaido

7 Urban Models 3 models explaining where people settle in cities
Based on Chicago—prairie city

8 Concentric Zone Model E. W. Burgess 1923
Cities grow outward from a central area in a series of rings Size and width of rings may vary from city to city but order stays the same. CBD  Zone in Transition  working class homes  middle class homes  commuter zone

9 Concentric Zone Model Fig. 13-5: In the concentric zone model, a city grows in a series of rings surrounding the CBD.

10 Sector Model Homer Hoyt 1939 City develops in sectors, not rings
Certain areas of the city are more attractive for different activities, as a city grows these expand in a wedge

11 Sector Model Fig. 13-6: In the sector model, a city grows in a series of wedges or corridors extending out from the CBD.

12 Multiple Nuclei Model Harris and Ullman 1945
City is a complex structure that includes more than one center for activities to revolve around. i.e. a port, neighborhood business center, university, airport, parks Different nodes attract and repel

13 Multiple Nuclei Model Fig. 13-7: The multiple nuclei model views a city as a collection of individual centers, around which different people and activities cluster.
