11. Functional specialization in a national urban system: Cities specialize in certain functions; more significant centers serve a wider array of functions (Knox and Marston 2001).

12. Rank-Size Rule – In a model urban hierarchy, population of a city is inversely proportional to its rankRank-Size Rule – In a model urban hierarchy, population of a city is inversely proportional to its rank Largest city = 12 millionLargest city = 12 million 2 nd largest = 6 million (1/2)2 nd largest = 6 million (1/2) 3 rd largest = 4 million (1/3)3 rd largest = 4 million (1/3) 4 th largest = 3 million (1/4)4 th largest = 3 million (1/4)

44. Central Place Theory Centrality – crucial to development of urban places and their service areasCentrality – crucial to development of urban places and their service areas By Walter ChristallerBy Walter Christaller Attempts to explain how and where central places in the urban hierarchy would be spatially and functionally distributedAttempts to explain how and where central places in the urban hierarchy would be spatially and functionally distributed

45. Nested hexagonal market areas predicted by Central Place Theory Central Place Theory -Spatial model of the sizes and location patterns of settlements that serve as central places for nested hierarchy of market areas

46. CPT Theory attempts to explain the size and distribution of cities in terms of a competitive supply of goods and services to dispersed populations.

47. Central Place Theory - Assumptions Geographic assumptions (Christaller, 1930s) - “featureless” landscape on an infinite plane - uniform population distribution Behavioral (economic) assumptions - consumers shop at the closest place possible - consumers do not go beyond the range of the good - firms’ market areas equal or exceed threshold of good Hexagonal market areas most efficient - nonoverlapping circles leave areas unserved - higher-order central places also offer lower-order functions

48. Central Place Theory

50. CPT - 2 Key Concepts Threshold - is the minimum market (population or income) needed to bring about the selling of a particular good or service. Range - is the maximum distance consumers are prepared to travel to acquire goods - at some point the cost or inconvenience will outweigh the need for the good.

51. The result of these consumer preferences is that a system of centers of various sizes will emerge. Each center will supply particular types of goods forming levels of hierarchy. Large cities serve as Econ. Hubs –Have most goods and services

52. Ex. lower order goods and services are: newspaper stalls, gas stations, groceries, bakeries, and post offices. –They are supported by a smaller threshold (population and demand). Ex. high order goods and services are: jewelry, large shopping arcades and malls, Casinos, IKEA, Pro Sports Teams. –They are supported by a much larger threshold.

53. 1. The larger the settlements are in size, the fewer in number they will be. –(many small villages, but few large cities) 2. The larger the settlements grow in size, the greater the distance between them. –villages are usually found close together, while cities are spaced much further apart. 3.As a settlement increases in size, the range and number of its functions will increase. 4.As a settlement increases in size, the number of higher-order services will also increase. –a greater degree of specialization occurs in the services.
