[Life tables, a concept of differentiation within a population]

"In this article a survey is presented of the different kinds of life tables published by the Netherlands Central Bureau of Statistics, such as cohort life tables for the Netherlands, regional tables of survivors for the eleven provinces and life tables by marital status." The author examines some problems concerning these life tables, discusses the utility of the increment-decrement method developed by Rogers and Willekens, and introduces an extension of that method that takes into account transitions as well as moves. This method is used to develop a life table by marital status for the Netherlands. (summary in ENG)
