Gambling surveys: the mystery of contradictory figures
For more than twenty years, estimates of the number of gamblers and people affected by gambling-related harm have varied greatly depending on the method used to collect them. On the one hand, face-to-face surveys such as the Health Survey for England (HSE) have long reported low rates. On the other hand, online or self-administered surveys, such as the Gambling Survey for Great Britain (GSGB), show much higher figures.
