By September 2011, there were more than 1,000 amateur roller derby leagues, covering every inhabited continent,^[1] with teams in countries such as Canada, Australia, the United Kingdom, New Zealand, Germany, Belgium, Finland, Sweden^[2] and Singapore^[3] In the UK, the sport is mostly played by women.^[4]

Contemporary roller derby has a basic set of rules, with variations reflecting the interests of a governing body's member leagues. The Women's Flat Track Derby Association (WFTDA), which is used by the majority of leagues around the world.^[5] For example, members of the United Kingdom Roller Derby Association are required to play by WFTDA rules,^[6] while members of the Canadian Women's Roller Derby Association are encouraged to join the WFTDA.^[7]
