Young people frequently use public space for social activity but their presence can be a source of suspicion and anxiety to members of the public. National and local policy on antisocial behaviour (ASB) and public attitudes to young people are both thought to be influential factors in this. This briefing, which draws on the experiences of young people growing up in a Scottish housing estate, explores young people’s understanding and experiences of ASB and, in particular, how they use and relate to public spaces.
