Mean Streets is a field study of young people who have left home and school and are living on the streets of Toronto and Vancouver. This book includes the personal narratives and explanatory accounts, in their own words, of some of the more than four hundred young people who participated in the summer-long study, which featured intensive personal interviews. The study examines why youth take to the streets, their struggles to survive on the street, their victimization and involvement in crime, their associations with other street youth, especially within "street families, " their contacts with the police, and their efforts to leave the street and rejoin conventional society. Major theories of youth crime are analyzed and reappraised in the context of a new social capital theory of crime.
