3URBANIZATION 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.

9Sources 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

11Urbanization 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

13Urban 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

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

18Urbanization 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 - Available at http//cepa.newschool.edu/het/

20Urbanization 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.
