This volume, Migration Psychology: Global Dynamics of Family, Policy, and Inclusion, is the second in a two-volume series that aims to foreground psychological perspectives within the broader field of migration studies. Volume 1 focussed on the United Kingdom (UK), exploring themes of identity, belonging, and the affective and internal dimensions of migration within a specific national context. In contrast, Volume 2 extends the lens outwards, tracing the global, structural, and transnational dynamics that shape the psychological lives of migrants across diverse locations and systems. The field of migration studies has long been multidisciplinary, engaging sociologists, anthropologists, geographers, legal scholars, and economists. Psychology has played a significant, though often backgrounded, role in shaping how migration is understood, particularly through concepts such as acculturation, resilience, identity development, and mental health. Yet, the term “migration psychology” itself has been curiously underused. One of the very few published works to explicitly adopt this terminology was James T. Fawcett’s, 1985 article, Migration Psychology: New Behavioural Models, which attempted to theorise the psychological motivations underpinning migration decisions through a behavioural lens (Fawcett, 1985). While that article stands as an early attempt to consolidate the psychological dimension of migration as a subfield, the term did not gain widespread traction in the decades that followed.
