This book examines the impact of migration on children within the European Union. The research involves in-depth interviews with parents and children of EU migrant families in Sweden, Portugal, Greece and the UK. It assesses the relevance of European citizenship to children and charts recent developments in EU policy-making and the promotion of children’s rights. The authors describe the experiences of the children with a focus on patterns of migration, the involvement of children in migration decision-making, and the impact of moving on their life chances in the receiving countries. In addition, the book describes and evaluates an innovative approach to the development of interdisciplinary and child-centered methods in comparative research.
