Ipsos MORI, on behalf of the National Lottery Commission, conducted research among 11- 16 year olds to identify the prevalence of underage gambling on National Lottery and other forms of gambling, where and how National Lottery tickets are bought, how much young players spend on Lotto and the extent to which parents play a role in children’s exposure to the National Lottery. The findings are based on data from a representative sample of 2,595 11-16 year olds attending 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 aged 11-15 who are not legally old enough to play the National Lottery, but also draws on results from children aged 16 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 in 2012, 2011, 2008 and 2007.
