urbanization
refers to the movement of people to towns/cities and the resulting expansion of the rural countryside

influences on urbanization
changes in transportation and communication, population growth, migration, economic
development, and government policies
3
New cards
central city
an urban settlement that has been legally incorporated into an independent, self-governing unit known as a municipality
4
New cards
urban area
consists of a central city and its surrounding built-up suburbs.

New cards
urbanized area
is an urban area with at least 50,000
inhabitants
6

urban cluster
an urban area with between 2,500 and 50,000 inhabitants
7
New cards
Central business district (CBD)
the most central place in a city, with a high concentration of public services, business services, and consumer services

the process of legally adding land area to a city
13
New cards
causes of rise of suburbs
\-Prefab Housing Production

\-More land at cheaper cost

\-Social and demographic trends – white flight, fear of crime
14

sprawl
the development of low-density suburbs in locations not contiguous to the existing built-up area.

based on:

Range: maximum distance people are willing to travel to use a
service

Threshold: minimum number of people needed to support a
service

Suggests people with the same ethnic or racial background are likely to live near each other
29

galactic (peripheral) model
where an urban area consists of an inner city surrounded by large suburban residential and service nodes or nuclei tied together by a beltway or ring road.
30
New cards
European city structure
* The CBD will have high-density residential areas. It will also feature consumer services directed to a residential population

on the periphery
31
New cards
Latin American City Model
a spatial city model that includes a prestigious, commercial axis (spine)
which emanates outward from the CBD and is surrounded by
a peripheral area containing squatter settlements; the city structure
can be attributed to colonialism, the rapid rise of industrialization,
and rapid population increase

32
New cards

a spatial city model that includes an old colonial port zone that is the
focal point of the city reflecting a city oriented around exports, and
radiating outward from the port zone are the Western commercial zone
and Alien commercial zone
a spatial city model that includes an old colonial port zone that is the
focal point of the city reflecting a city oriented around exports, and
radiating outward from the port zone are the Western commercial zone
and Alien commercial zone
33
New cards
Sub-Saharan African City Model
a spatial city model that is difficult to formulate due to the imprint of European colonialism, but often consists of a colonial CBD as well as a traditional CBD, and a market zone that is surrounded by squatter settlements (informal satellite townships)
