Compare over time changes to: world population levels, population density, and life expectancy. Use worldmapper. org to look at demographic trends. Tate malthus" predictio(cid:374)s o(cid:374) populatio(cid:374)s, and what he failed to predict. Predicted: human populations would continue to grow geometrically. Food production would grow arithmetically, due to diminishing marginal returns.

Stage 1: preindustrial society high and unstable birth and death rates; population growth rate slow; importance of children; low life expectancy. Stage 2: early industrial society high birth rates; falling death rates; high population growth. Stage 3: late industrial society low death rates; falling birth rates; high population growth. Stage 4:post industrial society low birth and death rates; low population growth. Population = (t + n) population(t) + (births deaths) + (in out migrants) The higher the income, the lower the population growth.
