Study Notes
- Central place theory explains the spatial-hierarchical ordering of cities.
- It was developed by Walter Christaller in the 1930s to explain the urban pattern of southern Germany.
- Central places are a particular class of cities that provide goods and services to a dispersed population.
- Traditional classifications of cities define three functional types: transportation cities, production cities, and central places.
- The model assumes a linear market with a constant density of consumers and only one undifferentiated good or service offered at central places.
- Consumers have downward sloping demand functions and the effective price for a consumer is the sum of a fixed purchase price and a travel cost proportional to their distance from the central place.
- Sales of the central function are increasing in the density of consumers and a decrease in the transportation rate will increase sales.
- The model produces complex spatial patterns, but its underlying mechanisms can be understood by starting with the simplest situation.
- Central place theory is a powerful model in economic geography, despite its predicted patterns not fitting the urban systems of the 21st century very well.
- Models provide possible explanations for the observed patterns in reality, but cannot reproduce the real world precisely.
- Central place theory explains the distribution and spacing of urban centers.
- The threshold distance is the minimum sales level required for a firm to break even.
- The range distance is the maximum distance people would travel to consume a central function.
- The number of central places that can fit in a market is determined by the threshold sales level and its related threshold distance.
- The hexagonal market areas are used to define exclusive market areas around evenly spaced central places.
- The hierarchy of urban centers arises from the variability of thresholds for different central functions.
- The spacing and number of central places depend on the required threshold distance and sales.
- The pattern of firm locations determines the pattern and density of urban locations.
- The density of cities is determined by the threshold, which is a reflection of scale economies.
- The range provides a rationale for the dispersed pattern of cities.
- Central place theory explains the spatial distribution of urban centers and services.
- It assumes an undifferentiated plane and that consumers prioritize distance in their spatial choices.
- The theory defines central places based on the order of services they offer, with higher-order services requiring larger market areas.
- The number of second-order centers depends on the ratio of market areas between first and second order.
- A k=3 system yields a hierarchical pattern of nesting market areas, but other values of k can produce different patterns.
- The k=4 system is known as the transport principle and the k=7 system as the administrative principle.
- Central place theory has limitations in real urban systems due to differentiated goods and services, varied natural landscapes, and hybrid functional types.
- Empirical studies have applied central place theory to agricultural regions with relatively undifferentiated terrain, confirming some of its principles.
- Christaller's application of the theory to southern Germany at the beginning of the twentieth century is a famous example.
- Berry's study of southwestern Iowa used modern statistical methods to define urban hierarchies based on the variety of goods and services offered and traced spatial patterns of consumer travel.
- Central place theory is still useful in modified versions for analyzing modern retail systems.
- It generates testable hypotheses that can be addressed by statistical analysis.
- Archeologists use central place theory to understand settlement patterns from societies without written history.
- The Mayan civilization had a hierarchical urban pattern that was explained by central place theory.
- Mayan settlements were spaced evenly and structured according to a hexagonal lattice.
- Central place theory introduced the notion that a city's place in the hierarchy may be defined by the variety of goods and services it provides.
- It established a point of departure for the study of systems of cities.
- New models of urban systems have been developed through adjusting the logic of central place theory.
- The Mayan settlement pattern emerged out of dependency relationships between settlements with different functions and levels of importance.
- The regularly spaced and hierarchical settlement pattern of the Mayan civilization was not necessarily planned or recognized by the Maya themselves.
