Unit 2 b) - Christaller Central Place Theory
Terms in this set (22)
Central Place Theory is a model to: predict/would be
predict how and where central places in the urban hierarchy/would be functionally and spatially distributed.
settlement which provides one or more services for the population living around it.
• Lower order: def/ex
simple basic services/grocery stores
• High order: def/ex
• Having high order service implies
there are low order services around it, not vice versa
• Sphere of influence:
area under influence of Central Place.
• Threshold population:
minimum population size required to profitably maintain a service.
Factors affecting fall in threshold population: 2 - decrease/change/introduction of
Decrease in population/Change in tastes/Introduction of substitutes
Conclusions that can be made about Central Places: larger the settlement, (3)
fewer their number, farther away a similar size settlement is, higher the order of its services
Conclusions that can be made about Central Places: less there are of a settlement/places
larger the hinterland, sphere of influence of goods and services/[laces of the same size will be spaced the same distance apart
Five Assumptions: +1 pp
surface flat/no physical barriers, soil fertility universal, population evenly distributed, uniform transport network, constant max distance or range for sale of any goods, similar purchasing power for all consumers
Best shape is/why
hexagon/prevent spheres of influence overlapping/having gaps
where consumer is equidistant from two/more similar services.
Primate Cities Rank-Size Rule developed by:
Geographer Mark Jefferson
Primate Cities Rank-Size Purpose:
explain phenomenon of huge cities with large proportion of country's population/economic activity.
• Characteristics: primate cities (2)
national focal-point, pulls in additional residents due to size/activity
Primate city: def
one larger than combined populations of the second and third-ranked cities in a country.
Primate city: examples/secondary cities
Paris, London, Mexico City/Marseilles, Birmingham, Guadalajara
Countries that Lack Primate Cities: 5
India, China, Canada, Australia, Brazil
Rank-Size Rule: developed by
Rank-Size Rule: theory purpose/theory is
explain size cities in a country/second-largest contains proportion of largest city population
Theory applied to which countries (3)
Germany, China, Midwestern US
