Ipsos MORI, on behalf of the Gambling Commission, conducted research among 11-15 year olds to identify the prevalence of underage gambling in various forms of gambling. The findings are based on data from a representative sample of 2,275 11-15 year olds attending academies and maintained schools in England and Wales. The research was conducted in a sample of schools, with pupils filling out paper self-completion questionnaires under supervision by Ipsos MORI’s interviewers. This report focuses on children, under the age of 16, who are not legally old enough to play the National Lottery, but also draws on results from 16 year olds for comparative purposes. Respondents aged 11-15 are referred to throughout the report as ‘children’ and those aged 16 as ‘young people’. Where possible, comparisons are made with previous studies examining the prevalence of underage gambling conducted via the Ipsos MORI Young People Omnibus in 2014, 2013, 2012, 2011 and 2007, and the 2008/09 British Survey of Children, the National Lottery and Gambling.
