In this groundbreaking Research Handbook on the Sociology of Youth, researchers from around the world examine the social, political, cultural and ecological processes that shape young people's lives and how young people in turn shape the world. Contributors from the Global North and South challenge traditional frameworks as they document the diversity of ways young people now live. The Handbook highlights the active and creative responses of young people as they help shape the world and how they work to overcome inequality, adversity and crisis and aspire to flourishing societies and a healthy planetary future.
