For many children and young people, Britain is a harmful society in which to grow up. This book contextualizes the violence that occurs between a small number of young people within a wider perspective on social harm. Aimed at academics, youth workers and policy makers, the book presents a new way to make sense of this pressing social problem. The authors also propose measures to substantially improve the lives of Britain’s young people in areas ranging from the early years to youth services and the criminal justice system.Youth violence dominates headlines and politicians’ attention and many organisations invest considerable resources in an attempt to reduce it. This book examines how social harms in young people’s lives can drive such violence and affect all the social situations they navigate. Drawing on empirical data from young people, police forces, emergency units and schools, the book highlights key future goals for researchers, policymakers and practitioners.
