Age is a measure of how many years a person has already lived. In contrast, our new approach to measuring age is concerned about the future. In this paper, we first explore our new age measure in detail and show, using an analytic formulation, historical data, and forecasts, that it is, in most cases, insensitive to whether it is measured using period or cohort life tables. We, then, show, using new forward-looking definitions of median age and the old age dependency ratio, how combining the traditional age concept and our new one enhances our understanding of population aging. 2007-01-16 published Max Planck Institute for Demographic Research doi:10.4054/DemRes.2007.16.2 265 270 public Demographic Research 16 2 27-58 TRUE 1435-9871 FALSE no info:eu-repo/semantics/article
