In the 21^st century, the populations of the world s nations will display large and long-lived changes in age structure. Many of these began with fertility change and are amplified by declining mortality and by migration within and between nations. Demography will matter in this century not by force of numbers, but by the pressures of waves of age structural change.

Many developing countries are in relatively early stages of fertility decline and will experience age waves for two or more generations. These waves create shifting flows of people into the key age...

Demography relates observable facts about individuals to the dynamics of populations. If the dynamics are linear and do not change over time, the classical theory of Lotka (1907) and Leslie (1945) is the central tool of demography. This book addresses the situation when the assumption of constancy is dropped. In many practical situations, a population will display unpredictable variation over time in its vital rates, which must then be described in statistical terms. Most of this book is concerned with the theory of populations which are subject to random temporal changes in their vital...

This final volume in a series of three examines the economic, social and demographic consequences of the transformations in the structures of population and family. These consequences include changes in economic behavior, both in labor and financial markets.

In the summer of 1993, twenty-six graduate and postdoctoral stu dents and fourteen lecturers converged on Cornell University for a summer school devoted to structured-population models. This school was one of a series to address concepts cutting across the traditional boundaries separating terrestrial, marine, and freshwa ter ecology. Earlier schools resulted in the books Patch Dynamics (S. A. Levin, T. M. Powell & J. H. Steele, eds., Springer-Verlag, Berlin, 1993) and Ecological Time Series (T. M. Powell & J. H. Steele, eds., Chapman and Hall, New York, 1995); a book on food webs is in...

Population growth slowed across the world in the last decades of the 20^th century, changing substantially our view of the future. The 21^st century is likely to see the end to world population growth and become the century of population aging, marked by low fertility and ever-increasing life expectancy. These trends have prompted many to predict a gloomy future caused by an unprecedented economic burden of population aging. In response, industrialized nations will need to implement effective social and economic policies and programs.

This is the final volume in...
