This article is an introduction to Special Collection 6 of Demographic Research whose articles investigate the interrelations between the family and migration behaviour of individuals in industrialised countries. We first review the life-course approach and previous research on the interplay between family change and migration. We then describe the contribution of the articles in the collection. This is followed by a discussion of selected issues raised in the papers and an outline of future research avenues. We argue that the life-course approach and event-history analysis offer a fruitful framework to examine how individuals simultaneously structure their family lives and residential trajectories, and thus shape demographic change in society.
