Key Terms:
  • demography
  • age structure
  • survivorship
  • fertility rate
  • migration
  • life expectancy
  • demographic transition
Main Ideas:
  • Human population growth has accelerated in the last few centuries.  The main reasons for this growth were improvements in hygiene and increases in food production, which accompanied the industrial and scientific revolutions.
  • Demographers try to predict population trends using data such as age structure, survivorship, fertility rates, migrations, and life expectancy.
  • In the demographic transition model, countries progress through four stages of change in birth rates, death rates, and population size.
