Greyhound racing is a sport in the United Kingdom. The industry uses a parimutuel betting tote system with on-course and off-course betting available. Attendances have declined in recent years, partly due to the decrease in evening fixtures with the majority of fixtures being held in the daytime. Attendances peaked in 1946 at around 70 million and totalisator turnover reaching £196,431,430. As of September 2022, there are 20 licensed stadiums in the United Kingdom (excluding Northern Ireland) and two independent stadiums (unaffiliated to a governing body).
