All the witnesses who have spoken to us about the available data have without exception criticised the lack of reliable data and the urgent need for more research https://www.onlinecasinoitaliani.com/recensioni/gioco-digitale/. The British Gambling Prevalence Survey (BGPS) was a nationally representative survey of participation in gambling and the prevalence of problem gambling in Great Britain.

Three surveys were carried out in the series—in 1999 (commissioned by GamCare) and in 2007 and 2010 (commissioned by the Gambling Commission). The aims of the BGPS were to measure the prevalence of participation in all forms of commercial and private gambling (including estimates of expenditure and information on venue); estimate the prevalence of problem gambling and look at which activities have the highest prevalence of problem gamblers; investigate the socio-demographic factors associated with gambling and with problem gambling; and to assess attitudes towards gambling.

Since 2010 the BGPS has not been repeated, but instead the Gambling Commission has funded the regular inclusion of a less detailed set of questions roughly every two years in the Health Survey England (HSE) and the Scottish Health Survey (SHeS).

The Gambling Commission has also commissioned separate surveys of gambling behaviour in Wales. These studies have been used together to report on gambling behaviour in Great Britain. However, the reduced length of the questionnaire that can be included in HSE and SHeS compared with the BGPS means that detailed evidence on key topics has not been collected more recently. For example, detail from BGPS about specific engagement in gambling activities, such as frequency and expenditure, was used to produce valuable evidence about the proportion of spend attributable to problem gamblers.
