The study combines the new measures of aging with probabilistic projections from the United Nations and predicts an end to population aging in the U.S. and other countries before the end of the century. Population aging -- when the median age rises in a country because of increasing life expectancy and lower fertility rates -- is a concern for countries because of the perception that population aging leads to declining numbers of working age people and additional social burdens.
