Chapter 1Introduction

Rogers, Andrei; Raymer, James; Little, Jani

Pages: 1 –8

[In countries with well-developed data reporting systems, demographic estimation is based on data collected by censuses and vital registration systems. In countries with inadequate or inaccurate data reporting systems, demographic estimation must rely on methods that are more “indirect.” Such...

Chapter 2Describing Age Structures of Migration

Rogers, Andrei; Raymer, James; Little, Jani

Pages: 9 –28

[Empirical schedules of age-specific rates exhibit remarkably persistent regularities in age pattern. Mortality schedules, for example, normally show a moderately high death rate immediately after birth, after which the rates drop to a minimum between ages 10 and 15, then increase slowly until...

Chapter 3Describing Spatial Structures of Migration

Rogers, Andrei; Raymer, James; Little, Jani

Pages: 29 –45

[The notion of age structure is a central concept in demography, but the structure of migration, which is inherently spatial, is not commonly presented. The former has been used to develop functional representations of the age patterns of a population or that of a stream of migrants, and it is...

Chapter 4Smoothing Age and Spatial Patterns

Rogers, Andrei; Raymer, James; Little, Jani

Pages: 47 –85

[A comparison of an observed pattern of age-specific rates or probabilities with the corresponding model schedule fitted pattern identifies idiosyncrasies in the observed data and points to possible data errors or to irregularities created by an insufficiently large sample. Actuaries calculating...

Chapter 5Imposing Age and Spatial Patterns

Rogers, Andrei; Raymer, James; Little, Jani

Pages: 87 –119

[The methods proposed in this chapter are particularly useful when sample sizes are insufficient to provide reliable age-specific migration flows. These procedures rely both on the survey data in question and on known regularities in migration schedules that have been observed within larger...

Chapter 6Inferring Age and Spatial Patterns

Rogers, Andrei; Raymer, James; Little, Jani

Pages: 121 –153

[In this chapter, we focus on methods for estimating migration flows in the absence of migration data. To obtain the patterns of interest, we use auxiliary information. Our examples illustrate both current and historical applications of indirect estimation. In Section 6.2, a model for estimating...

Chapter 7Conclusion

Rogers, Andrei; Raymer, James; Little, Jani

Pages: 155 –158

[Mortality, fertility, and migration rates combine to shape the temporal evolution of multiregional populations, and demographers study how the levels, age profiles, and spatial patterns of these contributors to population change vary over time and space. What they have discovered is that all...
