United States
According to the U.S. Department of Justice, approximately 500 motorcycle gangs were operating in the United States in 1991, with a combined membership of several thousand. These gangs range in levels of criminal sophistication, from groups of thugs to well-organized criminal networks. A government survey published in 1990 found that outlaw motorcycle gangs control 40% of the traffic of dangerous drugs in the U.S., including three-quarters of the methamphetamine trade. A subsequent study concluded that outlaw motorcycle gangs control or are heavily involved in the sale of meth in 38 states.
