This report presents results from NatCen’s British Gambling Prevalence Survey (BGPS) 2007. This is the second nationally representative survey of its kind, and its overall aim is to provide data on participation in gambling, and the prevalence of problem gambling, in Britain. A random sample of 9,003 individuals participated in the survey. Since the 1999 survey, the nature of gambling in Britain has changed substantially – due to changes in legislation, and an increase in the number of gambling products available. As well as allowing comparison with results from 1999, this survey provides baseline data for the new Gambling Act which came into force on 1 September 2007.
