This volume explores the family formation and life course of Polish people in Ireland, who make up the largest immigrant group in Ireland. Chapters address key dimensions of the life course in three parts focusing on childhood and youth, adulthood and parenting, and mid-life and futures. Contributions investigate the experiences of children and youth attending school and understanding their identities, the changing nature of families and family support, how families might engage with welfare institutions, and more. Through the life course approach, the book moves beyond the paradigm of studying the Polish population as economic migrants and instead analyzes and illustrates the lives of Polish families living in Ireland since EU enlargement.
