ABSTRACT
The principal objective of this paper is to develop and illustrate an analytic strategy for assessing the health care implications of the aging of human populations. The paper first reviews recent trends in population aging as well as changes projected to occur over the next several decades. I conclude that the most severe impacts of population aging will be experienced by the less developed nations, largely owing to the rapidity of their population aging and the absolute numbers of elderly added to the population over the period examined.
