Book excerpt: Childhood and Migration in Europe explores the under-researched and often misunderstood worlds of migrant children and young people, drawing on extensive empirical research with children and young people from diverse migrant backgrounds living in a rapidly changing European society. Through in-depth exploration and analysis of the experiences of children who moved to Ireland in the first decade of the 21st century, it addresses the tendency of migration research and policy to overlook the presence of children in migratory flows. Challenging dominant adult-centric perspectives on contemporary global migration flows and presenting understandings of the lives of migrant children and young people from their own experiences, this book presents a detailed exploration of children's lives in four different migrant populations in Ireland. With a unique comparative perspective, Childhood and Migration in Europe advances upon current conceptualisations of migration and integration by interrogating accepted views of migrant children and focusing on children's own voices and experiences. It challenges the prevailing assimilationist discourses underlying much existing research and policy, which often construct migrant children as deficient in different ways and in need of 'being integrated'.
