The demographic transition (box 2-2 in chapter 2) Virtually all societies have gone through a transition from; high mortality, high fertility to low mortality, Stage 1: high birth rate and high, but fluctuating death rate. Stage 2: declining death rates, and continuing high birth rates. Stage 4: low death rates, and low, but fluctuating birth rates. Thomas r malthus, an essay on the principle of population (1798): population incrases geometrically, subsistence, arithmetically (much slower).
