Aging Societies: The Global Dimension

While all five countries share the prospect of an older population, variations in the size and timing of demographic change, as well as important differences in the structure of public programs for the elderly, suggest that population aging will have widely different implications in each country. In Germany and Japan, for example, the population will not only grow older but may actually decline because of low birth rates. The United States will experience less aging, but its debate over reform treats seriously the possibility of privatizing public retirement commitments.
