Because internal and international migration are typically conceptualized and measured separately, empirical evidence on the links between these two forms of population movement remains partial. This paper takes a step towards integration by establishing how internal and international migration precede one another in various sequenced relationships from birth to age 50 in 20 European countries. We apply sequence and cluster analysis to full retrospective migration histories collected as part of the Survey of Health, Ageing and Retirement in Europe in 2008-09 and 2017, for individuals born between 1950 and 1965. The results show that nearly all international migrants engage in internal mobility at some point in their lives. However, individual migration trajectories are delineated by the order of internal and international moves, the duration and timing of stays abroad, and the extent to which individuals engage in return international migration. Institutional and economic conditions shape the diversity of migration experiences.
