Book excerpt: This collection sheds light on diverse forms of collective engagement among young people. Recent developments in youth studies, and the changing global shape of socio-economic conditions for young people, demand new approaches and ideas. Contributors focus on novel processes, practices and routines within youth collectivity in various contexts across the globe, including Indonesia, Spain, Italy, Norway and Poland. The chapters pay particular attention to transitional phases in the lives of young people. Conceptually, the book also explores the strengths and limitations of a focus on collectivity in youth studies. Ultimately, the book makes the case for a focus on forms of collectivity and engagement to help scholars think through contemporary experiences of shared social life among young people.
