There is now a substantial body of research which examines the process of making decisions about moving. The questions of interest in that work and in this study using US data are, first, how do life course changes get translated into intentions to move, and second, to what extent are intentions realized or unrealized. This study extends previous work by considering a longer interval in the planning process, and by examining how life cycle changes create intentions, which in turn are translated, or not, into actual moves. We study the antecedents of the expressed intention to move and the outcomes which follow the expressed intention to move. We test the process of forming intentions and moving in the context of life course events and changes. We find that the subset of variables which create the intention to move vary subtly from the variables which create moves, though the triggering effects of family composition change are critical dimensions of both creating intentions and fulfilling those intentions by moving.
