Reflecting the fact that migration processes evolve in space and over time, often through a series of logically linked stages, the chapter provides an overview of a range of migration transitions and sequences. It begins with a critical review of Zelinsky’s hypothesis of the mobility transition and proceeds to exemplify how various types of migration and mobility are sequenced and patterned across the globe. Included in the review are internal and international migration; emigration, return and onward migration; net emigration and net immigration; step migration; migrants’ shifts in status; and the wider issue of migration versus mobility. Such sequences and transitions are related to changes in economic structure, to political regimes of migration facilitation and control, and are embedded in individual and family life courses and biographies.
