Beginning around the mid-1980’s jurisdictions throughout North America started doing research to determine the prevalence of problem gambling. Renowned researchers Jamie Wiebe, Ph.D. and President of Factz Research and Rachel Volberg, Ph.D. and President of Gemini Research have examined the results from over 100 problem gambling prevalence studies spanning 20 years and multiple, worldwide jurisdictions. Their goal: to better understand the prevalence of problem gambling across time and jurisdiction.
