Study Notes

Population Growth/Decline

  • Global population reached 7 billion between 2011 and 2012, growing exponentially.
  • Population distribution varies globally.
  • Population growth is studied through demography, examining changes in population size and makeup.
  • Key factors in population change include fertility, mortality, and migration.

Fertility and Birth Rates

  • Fertility rate measures the number of children born in a society.
  • Crude birth rate measures live births per 1,000 people per year.
  • General fertility rate measures live births per 1,000 women aged 15-44.
  • The US general fertility rate is approximately 65.5.

Mortality and Death Rates

  • Mortality rate measures deaths in a population.
  • Crude death rate measures deaths per 1,000 people per year.

Migration

  • Immigration is the movement into an area.
  • Emigration is the movement out of an area.
  • Migration can be voluntary (like student exchange), involuntary (refugee crisis), or forced (displacement).
  • Migration can be domestic or international.

Population Growth Theories

  • Malthusian Theory: Predicted population would outstrip food supply, leading to famine, war, or disease.

  • Factors driving population growth include increase in food production, advancements in medicine, and use of contraception.

  • Zero Population Growth: A researcher named Paul Ehrlich suggested the environment is crucial to population sustainability.

  • Cornucopian Theory: Claims human ingenuity can solve issues, like food shortage, through technological advancement.

  • Demographic Transition Theory: Explains population growth in stages of social evolution.

    • Early stages: High birth and death rates.
    • Mid stages: High birth rates, lower death rates (population growth).
    • Late stages: Low birth and death rates (slow or no population growth).

Population Control

  • Societies sometimes attempt to control population growth through policies.
  • Pronatalist policies aim to encourage childbearing.
  • Antinatalist policies aim to discourage childbearing.
  • Migration restrictions control population influx or outflow.
