History of world population growth
demographic transition theory
the technological advances that gradually slow population increase
-currently world is gaining 83 million people each year, with 97 percent of its increase taking place in poor countries
-world population expected to reach 9 billion by 2050
-4 stages of demographic transition:
1-high birth and death rates, pre-industrial, very slow pop growth
2-high birth rates, declining death rates, early industrial, rapid pop growth
3-slowing birth rates, low death rates, mature industrial, slowing pop growth
4-low birth and death rates, post-industrial, very slow pop growth
zero population growth
the rate of reproduction that maintains population at a steady level
First urban revolution
second urban revolution
third urban revolution
- today, most of worlds largest cities are found in less developed nations
