Models of Population Structure

This chapter describes population structure and population dynamics. It begins by describing in Section 13.2 what demographers mean by the age structure of a population. Section 13.3 describes in general terms how the age structure of a population is related to its rate of growth, and hence to its fertility and mortality experience. A population’s age structure is shown to be a dynamic, changing thing, revealing aspects of a population’s demographic history, as illustrated in Section 13.4, and anticipating aspects of its demographic future.
