The potential for substantial changes within a relatively short time makes it more difficult to construct accurate forecasts of fertility rates than mortality rates. In this chapter, we describe several fertility measures and discuss two differentCamouflage 发表于 2025-3-28 20:44:05

In this chapter, we discuss a variety of concepts, measures, and definitions of mobility and migration. We describe data sources that can be used to collect migration information aterazosin 发表于 2025-3-29 01:18:55

We begin with a discussion of several issues that must be considered when setting up a cohort-component model. Then, we present three step-by-step exampl享乐主义者 发表于 2025-3-29 06:54:43

One common adjustment is for special populations such as college students and prison inmates. There are also circumstances in which a set of projections must be controlled to an independent projection or adjusted to provide addit无脊椎 发表于 2025-3-29 15:48:50

Given the many critical decisions based on those projections, it is essential to evaluate the forecast accuracy and bias of commonly used projection methods. This chapter provides such an evaluation.
