GEOG 130 Lecture Notes - Lecture 5: Demographic Transition, One-Child Policy, Government Failure
Document Summary
Population pressure: not size, not density, not growth rate, not the ability to feed themselves, political organization: available land, technology to work the land, large scale organization to manage it. Stopping point is between 8 and 10 billion. Very western experience: it"s still helpful to show us what drives the change even though it"s western. Foundation of model: tomas malthus, principle of population, 1789. Exceptions to model: example: china, they had such a strong central government so they enacted the one child policy. Lowered fertility rate: it took china decades to reach a stable population growth. Delayed models: example: latin america, no contraception religion, birth rate is higher for longer. Birth and death rates are both very high. Population is very small and population growth is very small. Population doubling time is 25 years (estimated number of years for a population to double assuming all other things stay the same)
