Demographers and economists concerned with population growth in the past must now turn to understanding the implications of population aging and the options for adapting to it. Although the extent of population aging, current and anticipated, constitutes a new phenomenon in human history, research may draw on previous studies of the mechanisms that link demographic change and economic outcomes. Two broad population trends have been observed over the past decades. On the one hand, the "population explosion" about which so much has been written seems to be continuing in some parts of the world - particularly in Africa, the Arab world, and parts of South Asia. On the other hand, in a number of countries the birth rate has fallen so much that the population is rapidly aging, and in some cases beginning to shrink. Hence the world includes countries where rapid population growth is considered a major development obstacle, but also ones where policymakers believe that their fertility level is already too low and that the associated rapid population aging will negatively affect old-age security, international competitiveness, and hence economic growth....
