In 1992, a summer course 'Demographic Perspectives on Living Arrangements' as well as a one-day workshop 'Recent Issues in Household Modelling' were held in Wassenaar, The Netherlands. This volume is based on the lectures delivered during the summer course, as well as on the presentations made in the workshop. As such, the present volume combines the two elements of transfer of knowledge, on the one hand, and updating the state-of-the-art in the field of household demography, especially in household modelling, on the other hand. In organizing the contents and structure of this volume, we have aimed at creating a book that covers the field of household demography and household modelling in a certain logical and comprehensive way. The purpose of this book is to offer a comprehensive treatment of recent developments in various aspects of the growing field of household demography. Since these recent developments have particularly occurred in household analysis and modelling, these topics will receive special emphasis. The book was written for demographers, social scientists, and planners who are involved in the study and projection of popUlation in general, and of households in particular.
