- What has occurred?
o Urban growth
o Urbanization
Variations in Levels of Urbanization:
- Proportion of the population
living in urban areas:
o C.1800 (or prior to the
industrial revolution)
▪ ~3% (world) vs.
~10% MDW
o 1900:
▪ ~14% World vs.
~50% MDW
o Today (2015):
▪ ~80%MDW vs
~48% LDW
- urbanization mirrors industrialization and economic development
Urban Population (as Percent of Population):
- MDW i.e. the ore is ore highly uraized i.e. >75% tha the LDW
