This text offers a critique of mainstream conceptions of youth, the programmes and strategies designed for "at risk" young people, and policy development in youth affairs. The authors challenge conventional wisdoms, providing a systematic overview of the major perspectives in youth studies. They demonstrate how the concept of youth involves a tension between the social significance of age and the significance of other social divisions. Using examples from the UK, Europe, Australia and the US, the book examines debates surrounding youth and economy, youth development, youth subcultures, youth transitions and youth marginalization. It calls for greater sensitivity to the complexities of youth and greater emphasis on democracy and equality in dealing with the problems experienced by young people in a rapidly changing world.
