Warm Up • I want you to come up with a plan to control population growth here at AK. • How can we avoid overpopulation? • How do we make every class equal?
Population and Urbanization The worlds population is expected to exceed 9 billion by 2050!
In this chapter… What do you expect to learn? What do you want to learn? (do not say nothing) What factors do you think affect a populations growth/decline?
What do you remember about… Life expectancy Death Generations Adolescence Deviance
Population Concepts Demography Birthrate vs. Death rate Fertility vs. fecundity Mortality and infant mortality Migration
The 3 factors affecting population are Birthrate, death rate, and migration. How can these factors be used in controlling population growth? (Come up with examples)
Thomas Malthus • Malthusian Theory • Population growth will be outrageous! • Reduce the birthrate! (birth control, delayed marriage, sex control, etc.) • Preventive checks • Disease, war, famine • Positive Checks
Demographic Transition Theory • Population patterns based off of technology • Preindustrial (1)-Stable • Industrial(2)-High Birthrate, low death rate • Post industrial(3)-Low birthrate, high death rate • Some theorists think that stage 3 will result in Zero population growth. What do you think?
Controlling Population • Family planning (birth control, delayed child bearing, delayed marriage) • Economic Improvements • The more benefits available (education, jobs, etc.), the lower the birthrate. • http://usgovinfo.about.com/cs/censusstatistic/a/aabirthrate.htm
Closure What are the 3 factors that affect population? Explain.
