概要：In work using formal demography, Thomas Espenshade, Simon Levin (Ecology and Evolutionary Biology), and OPR graduate student Analia Olgiati have initiated a study on population momentum. The purpose of the project is to decompose total population momentum into two constituent and multiplicative parts called "weak" momentum and "strong" momentum. Weak momentum depends on deviations between a population's observed age distribution and its implied stable age distribution. Strong momentum is a function of deviations between a population's implied stable and stationary age distributions. In general, the factorization of total momentum into the product of weak and strong momentum is a very good approximation. The factorization is exact, however, if the observed age distribution is stable or if initial fertility is already at replacement.
