Title: URBANIZATION or HOW CITIES GROW


1
URBANIZATIONor HOW CITIES GROW
  • Geography 1050
  • The geography of cities

2
Outline
  1. Global patterns of urbanization
  2. Differences in urbanization between MDCs and LDCs
  3. Urbanization and the population question
  4. Urban service provision and urban economies in
    LDC cities

URBANIZATION CITIES
  • Urbanization refers to the proportion of people
    in living in cities.
  • It also refers to the process in which rural
    populations move to urban areas.
  • Urbanization refers to all of the cities in a
    country, considered as an urban system.
  • The urban system is the network of individual
    cities within a region or country.

Urbanization
  • The urbanization curve is typically logistic or

Sources of Urbanization
  • The urban system of a country grows mainly by
  • Natural population increase (births deaths)
  • Migration from rural areas (especially in
    countries with large rural populations)
  • Immigration from other countries (especially in
    Europe and North America)
  • Reclassification of urban boundaries to encompass
    formerly rural areas

Outline
  1. Global patterns of urbanization
  2. Differences in urbanization between MDCs and LDCs
  3. Urbanization and the population question
  4. Urban service provision and urban economies in
    LDC cities

11
Urbanization in MDCs and LDCs
  • MDCs
  • Slow pre-industrial growth
  • Rapid industrial growth
  • Slows again once most previously rural
    populations are in cities
  • Europe, North America, Australia and Japan, the
    population is 75 to 80 urban.
  • Canada is 80 urbanized.
  • LDCs
  • Rapid urbanization without proportional
    industrialization (population growth, land
    tenure)
  • By 2020 majority of LDC population will live in
    urban areas of 1 million
  • By 2020 most megacities of 10 million will be in
    LDCs

Urbanization
MDC urbanization
LDC urbanization
  • The urbanization curve is typically logistic or
    S-shaped

13
Urban Growth is Speeding Up
  • Time required to reach 2 million population
  • Rome, Italy 2000 years
  • Vienna, Austria 400 years
  • Vancouver, B.C. 115 years
  • Shenzhen, China 20 years

14
Share of World Population Growth Urban and Rural
Areas LDCs and MDCs 1950 to 2025
  • Over the next quarter century, increases in
    urbanization will be almost entirely attributable
    to sub-Saharan Africa and Asia

Cities with 10 million or more people 2015

Urbanization the population question Thomas
Malthus and Malthusianism
1766-1834
  • I SAID that population, when unchecked,
    increased in a geometrical ratio, and subsistence
    for man in an arithmetical ratio.
  • Thomas Malthus. 1798. An Essay on the Principle
    of Population

Urbanization the population question Thomas
Malthus and Malthusianism
1766-1834
  • Solution to unchecked population growth
    inculcate middle-class values in the
    lower-classes
  • Advocated universal sufferage, state-run
    education
  • But his analysis of population growth has been
    used to naturalize the idea of overpopulation
    as a purely mathematical problem ---gt buries
    struggles for power (politics) in apparently
    objective language of math.
