World Population Growth
J. Bradford DeLong
- Thirty years ago those fearful of the population explosion projected that population would reach 15 billion by 2050--if we didn't run out of food and suffer mass starvation beforehand.
- Today projections of human population in 2050 are much, much smaller: 9.3 billion.
- Birth rates have come down amazingly rapidly in much of the developing world.
- Slower rates of population growth will mean higher capital-output ratios, faster growth, and richer developing economies.
