This book brings together two major trends influencing economic and social life: population ageing on the one side, and migration on the other. Both have assumed increasing importance over the course of the 20th and into the 21st century. The book offers a unique interdisciplinary perspective on the challenges posed by the globalisation of the life course to welfare states' old age and family policies. Through a variety of case studies, it covers a wide range of migration scenarios: those who migrate in later life; migrants from earlier years who age in place; and old people who hire migrant caregivers. It shows how both local and global economic inequalities intersect to frame interactions between ageing, migration, and family support. Across a wide variety of situations, it highlights that migration can both create risks for older people, but also serve as an answer to ageing-related social, economic, and health risks. The book explores tensions between national and global contexts in experiences of migration across the life course. As such this book offers a fascinating read to scholars, students, practitioners, and policy makers in the fields of aging, migration, life course, and population health.
