This book explores the complex intersections of ageing, migration, and transnational family life. Migration reshapes family structures and alters the quality and dynamics of relationships across generations and borders. Rather than viewing ageing solely from the perspective of older adults, this edited volume conceptualizes ageing as a life-long process, offering important connections to life-course perspectives on families and intergenerational relationships. Amid intensified global mobility and population ageing, the chapters present both quantitative and qualitative research from diverse contexts around the world. Together, they illuminate underexamined groups and social settings in the fields of ageing and migration, expanding and deepening current scholarly debates. Drawing on data from a range of social science disciplines, the volume provides rigorous analyses of aged care, health, parenthood, gender, and culture. It reveals the multifaceted ways in which ageing shapes family relationships within the context of migration and transnationalism. The contributions examine how ageing migrants navigate their own experiences of growing older while living apart from their adult children and kin, and how migrants engage with notions of well-being, care, and filial obligation in relation to ageing parents who remain in their countries of origin. Interdisciplinary in scope, this book will appeal to scholars and students of migration studies, family sociology, social gerontology, diaspora studies, and anthropology, offering new insights into the lived realities of ageing and care in a transnational world.
