edge cities

clusters of large buildings and services away from the central business district

Exurbs

areas of new development beyond the suburbs that are more rural but on the fringe of urbanized areas

Boomburbs

Rapidly growing suburb cities

Decentralization

shifting of business and services out of the CBD (core) of the city to suburbs.

world cities

cities generally considered to play an important role in the global economic system

urban hierarchy

A ranking of settlements according to their size and economic functions.

globalization

resources

all things used in producing goods and services

physical geography

the study of physical features of the earth's surface

Interdependence

the dependence of two or more people or things on each other.

Distribution

The arrangement of something across Earth's surface.

Rank-size Rule

A pattern of settlements in a country, such that the nth largest settlement is 1/n the population of the largest settlement

primate city

The largest settlement in a country, if it has more than twice as many people as the second-ranking settlement.

Gravity model

A mathematical formula that describes the level of interaction between two places, based on the size of their populations and their distance from each other.

Central Place Theory (Christaller)

A theory that explains the distribution of services, based on the fact that settlements serve as centers of market areas for services; larger settlements are fewer and farther apart than smaller settlements and provide services for a larger number of people who are willing to travel farther.

Concentric Zone Model (Burgess)

A model of the American central city that suggests the existence of five concentric land-use rings arranged around a common center.

Sector Model (Hoyt)

A model that shows cities develop in a series of sectors radiating out from a CBD

Multiple Nuclei Model (Hans & Ullman).

A model of the internal structure of cities in which social groups are arranged around a collection of nodes of activities.

Galactic City Model (Peripheral Model)

model that represents distinct decentralization of the commercial urban landscape as the economy has to be transitioned to services as the leading form of production. Manufacturing declines significantly and becomes more specialized. There are several industrial parks.

Bid rent theory

theory that refers to how the price and demand on real estate changes as the distance towards the Central Business District (CBD) increases.

Latin American City Model

The CBD is dominant; it is divided into a market sector and a modern high-rise sector. The elite residential sector is on the extension of the CBD in the "spine". The end of the spine of elite residency is the "mall" with high-priced residencies. The further out, less wealthy it gets. The poorest are on the outer edge.

smart growth

city planning that efficiently uses and conserves land and other resources

A movement in urban planning to promote mixed use commercial and residential development and pedestrian friendly, community orientated cities. New urbanism is a reaction to the sprawling, automobile centered cities of the mid twentieth century.

Green belts

Areas around cities where suburban land uses are restricted.
