chapter 8 notes Flashcards
City characteristics:
Dense population concentrations
Functional complexity (the town can support lots of different workers – nonfarmers)
Centers of power (business, government, etc)
Specialised land use
Cities are linked (trade, transportation)
Contradictions (wealth/poverty)
Defining “urban”
No ingle definition of what constitutes “urban”
Is distinctively nonrural and nonagricultural
United States: > 2,500 people and 1,000 people/sq mile
Japan: > 50,000 people
Statistics Canada: > 1,000 and no fewer than 400 persons/km2 = “urban”
United Nations: settlements > 20,000 = “urban“
Urbanization area
Urbanized area
A continuously built-up landscape
Defined by building and population densities (not political boundaries)
May include a central city with town suburbs etc.
Metropolitan area
Large population centre and areas socially and economically connected to it
May contain several urban areas
urbanization
the process through which the proportion of population living in cities increases
1880: 5% of total global population lived in urban areas
1997: 43%
2025: Projected 61%
Megalopolis
High population density
Demand for goods from outside
Urban centers growing towards each other
Freeway culture
Megacities
Metrapolitian area with a population > 10 million
Primate Cities
a country’s leading city economically, culturally, historically, and politically
2x larger population than the next largest city
Dominates the population, political and economic landscape
World’s largest primate cities are in LDCs
(e.g. Lagos, Nigeria; Jakarta, Indonesia)
world cities
A centre of global economic power, influencing the world’s businesses
Two influential factors in creation of world cities:
Growth of multinational corporations
Concentration of professional services (banking sector, legal services, accounting, accounting )
centralization
Forces that draw people and business downtown
urban decentralization
when metropolitan areas sprawl in all directions and suburbs have characteristics of traditional downtowns
agglomeration
clustering of similar or unlike activities activities
urban land use
Land values reflect accessibility and desirability of a site
-Bid-rent curves show the amount a bidder will pay for land relative to distance from the CBD
Zoning law regulate land use
Central Place Theory
Walter Christaller, The Central Places in Southern Germany (1933), had five assumptions:
The surface of the ideal region would be flat and have no physical barriers.
Soil fertility would be the same everywhere
Population and purchasing power would evenly distributed
The region would have a uniform transportation network to permit direct travel from each settlement to the other.
From any given place, a good or service could be sold in all directions out to a certain distance.
Each central place has a surrounding complementary region, an exclusive trade area within which the town has a monopoly on the sale of certain goods
Hexagonal Hinterlands
Christaller chose perfectly fitted hexagonal regions as the shape of each trade area
Central Places Today
New factors, forces, and conditions not anticipated by Christaller’s models and theories make them less relevant today.
Ex.: The Sun Belt phenomenon: the movement of millions of Americans from northern and northeastern states to the South and Southwest.
