Central Place Theory AP Human Geography
Dispersed Rural Settlements
A rural settlement pattern characterized by isolated farms rather than clustered villages. Midwest
Linear Rural Settlements
Buildings clustered along a road, river, or dike to facilitate communications - fields extent behind the buildings in long, narrow strips. French Long-lot system
Circular Rural Settlement
Central open space surrounded by structures Kraal villages in sub-Saharan Africa
Central Place Theory
Explains the spacial arrangement, size, and number of settlements. Can be used to identify profitable location for services. 1933 German Geographer Walter Christaller
Business Services
Facilitate the activities of other businesses. i.e. Professional, financial, transportation, and information
Urbanization
Growth of Urban Settlements increase in number of people increase in the percentage of people living in cities
Disadvantages of Primate Cities
Housing Shortages Traffic congestion Crime & pollution Urban/rural inequalities Concentration of power supplies Increasing land value Progressive core
Advantages of Primate Cities
Large-scale economy Attract overseas investment Attractive places of migration Resources, services, and infrastructure
Primate City Rule
Largest settlement has more than twice as many people as the second ranking settlement Mexico City - 8.9 million Guadalajara - 1.5 million
Significant Fact
MDCs have a Higher % of urban residents ...but... LDCs have more large cities 8 out of 10 most populous cities Cario, Delhi, Jakarta
Primate City
Major City that works as the financial, political, and population center of a country.
Primate Cities Examples
Paris, London, Mexico City, and Bangkok
Enclosure Movement
Process of consolidating small land-holdings into a smaller number of larger farms in England during 18th century Single farms more efficient Village populations declined and moved to cities Industrial Revolution
Public Services
Provide security and protection for citizens and businesses. i.e. Government workers, Police, (public good)
Consumer Services
Provide services to individual consumers who desire them and can pay for them. i.e. Retail & Wholesale, Health & Social, Education, Leisure & Hospitality, Other U.S. Jobs
Distance Decay
The further away 2 cities or ideas are the less likely they are to interact and move directly related to the gravity model and Reilly's Law of Retail Gravitation
Rank Size Rule
a country' nth-largest settlement is 1/n the population of the largest settlement 1-100,000 2-50,000 3-33,333 4-25,000
Clustered Rural Settlement

Basic Industries
exports or consumers outside the settlement.
Outsourcing
insurance claims, transcription, celeriac work, low wages, speak english
Range
maximum distance people are willing to travel to use a service.
Threshold
minimum population required to support the service
Gravity Model
predicts the degree of interaction between 2 places
high order settlements

low order services
simple, basic services (grocery store)
Offshore Financial Services
small countries (i.e. islands or micro states) low or no taxes privacy and bank secrecy laws

Christaller Assumptions
*an isotropic (all flat) surface *an evenly distributed population *evenly distributed resources *similar purchasing power of all consumers and they will patronize the nearest market *transportation costs equal in all directions *no excess profits (perfect competition)
Reilly's Law of Gravitation
*variation of the gravity model *Reilly used this model to establish the hinterland *2 cities of the same size would have a trade area boundary exactly in the middle of each city - the smaller the city the *closer the hinterland. *boundary between both cities is known as the breaking point
