Malthusian Theory of Population Growth • In 1798, Thomas Malthus argued that the global population, if left unchecked, would exceed the available food supply. • While the population increases in a geometric (exponential) progression (e.g., 2, 4, 8, 16, 32, . . . ), food production would increase only arithmetically (e.g., 1, 2, 3, 4, 5, . . . ) • Disaster, according to Malthus, could only be averted by positive checks (e.g., famine, disease, and war) or preventive checks (e.g., sexual abstinence before marriage and delay of marriage) to limit people’s fertility. Demographic Transition Theory • According to demographic transition theory , societies move from high birth rates and death rates to relatively low birth and death rates as a result of technological development. The demographic transition takes place in four stages: 1) Preindustrial Stage – characterized by little population growth; high birth rates are offset by high death rates 2) Transitional or Early Industrial Stage
