Document Summary

Winter 2012, class 4: global variation in population aging. **2000: more developed nations over 14% of population is over 65, in the developing world nearly 4% of the population is over 65. In 2050 it is expected that ~27% of individuals will be 65+ in more developed nations and. 14% in less developed nations, however raw totals show 316 million people in more developed nations and 1140 million in less developed nations over 65 years old. However now a stage beyond the fourth stage is being observed - sub-replacement fertility rates, more deaths than births. Life expectancy increased dramatically as well (above projected estimates of 75). Wars, epidemics, etc can still affect populations; they are also not uniform (pattern does not look the same across countries). Type b pattern nations high fertility rate and smaller drop in mortality (than observed in type a nations). This pattern is seen in sub-saharan africa (effects of aids epidemic?).
