1 KI 2: Where are people distributed within urban areas? Ch. 13—Urban PatternsKI 2: Where are people distributed within urban areas?
2 Models of Urban Structure People concentrate in particular areas in urban settlements depending on their social characteristicsE.W. Burgess (1923)—Concentric Zone ModelCity grows outward from central area in series of ringsSize of rings will vary from city to city, but order and type of ring will be sameUse page 411 to identify the 5 rings in your notes
4 Models of Urban Structure Sector Model developed in 1939 by Homer HoytCity develops in a series of sectors, not rings
5 Models of urban structure Multiple nuclei model developed in 1945 by C.D. Harris and E.L. UllmanCity is complex structure that includes more than one center around which activities revolve (ie. Ports, neighborhoods, universities, airports)
7 Geographic applications of the Models 3 models help us understand where people with different social characteristics tend to live within an urban areaUsed to explain why certain types of people live in particular placesUrban areas in U.S. are divided into census tracts by U.S. Census Bureau—each tract contains roughly 5,000 residentsAllows for organized social area analysis—comparing distributions of characteristics to create an overall picture of where various types of people live
8 Example of concentric zone model in Dallas, the distribution of home owners. The % of households that own their home is greater in the outer rings of the city.
9 Example of sector model in Dallas, the distribution of high-income households. The median household income is the highest in a sector to the north.
10 Example of multiple nuclei model in Dallas, the distribution of minorities. African Americans and Hispanics occupy nodes to the south and west of downtown.
11 Applying Models outside of North America American urban areas differ from those elsewhere in world—differences do not invalidate the modelsEuropean CitiesWealthy Europeans still live in the inner rings of upper class sector (opposite of U.S.)See page 415 in textbook
12 Less developed countries Similar to Europe, poor are accommodated in suburbs and wealthy live near city centersEuropean colonial influence created this pattern in most LDCsPre-colonial cities—built around religious structures—wealthy families located near that centerWith rural to urban migration and high NIRs, LDCs have seen a growth of squatter settlementsHave few services (no $$ for them)See page 419 in textbook
