Residential migration is one of the most problematic demographic variables. In Britain there are no sources that routinely record all moves, and the motives behind relocation are rarely recorded. In this paper I argue that the use of life histories can add important depth and clarity to the study of residential moves. The paper focuses on two themes: the ways in which internal and international migration may be linked together over the life course; and the complex mix of reasons why a move may take place. Used sensitively, life histories and life writing can enhance the study of migration history.
