In recent decades, the term 'mobility' has emerged as a defining paradigm within the humanities. For scholars engaged in the multidisciplinary topics and perspectives now often embraced by the term Pacific Studies it has been a much more longstanding and persistent concern. Even so, specific questions regarding 'mobilities of return'-that is, the movement of people 'back' to places that are designated, however ambiguously or ambivalently, as 'home'-have tended to take a back seat within more recent discussions of mobility, transnationalism and migration. Situating return mobility as a starting point for social inquiry gives rise to important questions regarding the broader context and experience of human mobility, community and identity. This represents an important contribution to emerging perspectives that seek to move beyond binary optics of domestic or translocal versus international migration, local versus foreign identity, and indeed of stasis versus mobility itself. This introductory chapter foregrounds the ways in which the volume as a whole demonstrates the extent to which the prospect and practice of returning home, or of navigating returns between multiple homes, is a central rather than peripheral component of contemporary Pacific Islander mobilities and identities.
