This article invites you to explore migration processes, as they are experienced and constructed at both global and local scales, from the perspectives of migrant children and young people. We provide an overview of current geographical thinking on migration processes and the ways in which such processes shape the spaces and places in which we live, particularly highlighting the tendency to overlook children's and young people's roles in them. The article focuses on the emerging area of the geographies of child and youth migration. It highlights the important roles played by children and young people in global population movements and explores the spatialities of identity, belonging, mobility and settlement as these are shaped and experienced by migrant children and young people.
