Abstract

The methods of multiregional life table construction are explored through an investigation of a tree of choices with respect to approach, data, rates definition, probability definition, and stationary population or life-years-lived calculation. Two principal approaches are discussed: the movement approach and the transition approach, although a third label "hybrid approach" is used to characterize many of the developments in the field to date. Methods are applied to two population systems, that of the Netherlands, where moves data are available, and that of Great Britain, where the data on migration come in the transition form. The discussion of methods and the computer runs of the life table model lead to a clear set of recommended choices for the would-be life table constructor. The fairly simple and direct transition approach using migrant data measured by a five-year question is our preferred choice. The paper ends by speculating on how solutions to the unresolved problems of multiregional population analysis might be sought.
