Developed countries
Allowed cities to develop in ancient world
agricultural surplus, social organization and power
what does situation refer to in relation to a city's location?
the relative location
What is the basic sector of a city?
People doing work for areas outside the urban area
what is the non-basic sector of a city
People produce goods or services for residents of the urban area
Multiplier effect between basic and non-basic workers
Each basic worker needs non-basic workers to support them
suburb
segment of large urban area outside city
central city
within boundaries of main city
urbanized area
built-up landscape defined by building and population densities
metropolitan area
large-scale functional entity discontinuously built-up but nonetheless operating as an integrated economic whole
3 main functions of the city
1. Central place functions
2. Transport functions
3. Singular functions
Walter Christaller's Central Place Theory
1. Towns of same size evenly placed, larger- farther apart
2. System of towns are interdependent, if one eliminated, entire system readjusts
Cities as centers of production
circular and cumulative, resistant to decline
Cities as centers of administration
Always have govt. employees, education centers
urban hierarchy
ranking of cities based on size and function
Rank-size relationship
nth largest city is 1/n size of largest city
World Cities
stand at the top of national system, command and control centers of global economy
Changes after 1945 lead to urban sprawl
Improvements in automobiles, development of highway systems, increase in homeownership and 40 hr week
suburbanization
development of suburbs, residential came first, industries followed
Factors that lead to decline of city in late 20th century
cities congested, loss of jobs, loss of tax bases
What is different about cities in western U.S?
Rapid growth, sprawling expansion
gentrification
the rehabilitation of housing in oldest and now deteriorated inner-city areas by middle and high income groups.
Variables leading to ppl settling in different parts of urban areas
family status, social status, ethnicity
Characteristics of Western European cities
compact, high density, lower skyline, good public transportation system, built on previous city plans
Eastern European cities
compact, reflect communist planning principles, depend on public transportation
Cities in developing countries
fastest growing, some ancient cities, some colonial roots, some have modern technology, some dont.
