  1. Solution to the Malthusian Trap Preventive checks: birth control through (1) later age at marriage. (2)abstinence from sex outside marriage. (Malthus opposed artificial methods of birth control on moral grounds. Viewed contraception as a vice)

  2. Population Explosion Contrary to Malthus’s prediction, mortality has not yet risen to curb world population growth. < 1 billion people in 1800 6 billion by the end of the 20th century

  3. Population Explosion Why was Malthus unable to foresee the population explosion (also known as the population bomb)? He did not recognize the force of the Industrial Revolution, which produced exponential growth in the means of subsistence.

  4. The Demographic Transition During the first half of the 20th century, demographers conceived the notion of the demographic transition.

  5. The Demographic Transition The demographic transition framework illustrates population growth in terms of discrepancies and changes in two crude vital rates – mortality and fertility (ignores migration)

  6. CRUDE VITAL RATES Crude Death Rate (CDR) = # deaths in calendar year * k mid–year population

  7. CRUDE VITAL RATES Crude Birth Rate (CBR) = # deaths in calendar year * k mid–year population Rate of Natural Increase = CBR - CDR
