Dispersal Orders are one of a number of measures to tackle antisocial behaviour and have succeeded in tackling underage drinking, joyriding, noise nuisance, the antisocial use of fireworks and the harassment and intimidation of residents. They are not intended to be used in isolation, but should form part of a tiered and integrated response to tackling crime and disorder and antisocial behaviour in local areas. This includes work by YOTs to prevent young people getting involved in offending and antisocial behaviour.While no assessment has been made of the efficacy of dispersal orders on their own, a study and report by the National Audit Office (““Tackling Anti-Social Behaviour””, HC 99 Session 2006-07, 7 December 2006) confirmed that a tiered approach to tackling antisocial behaviour is highly effective. This is also borne out by the fact that we have driven down perceptions of antisocial behaviour by 4 percentage points from the baseline of 21 per cent. in 2002-03 to 17 per cent. in 2005-06.
