The Stable Population Model
This chapter introduces the concept of a stable population. It discusses the theory underlying the model. It also shows numerically how two or more populations subjected to constant fertility and mortality rates would result in the same proportionate age distribution. Methods of fitting a stable population and estimation of their demographic parameters are discussed and examples given. The chapter also reviews various systems of model life tables developed since they were first constructed by the United Nations in the 1950s. Further, the chapter examines their usefulness in countries where coverage of the civil registration system is not adequate, and particularly those populations where a substantial number of deaths is not reported. The chapter does not present specifically the indirect methods of estimation. It discusses their importance. It also describes steps that may be useful in their application.
