Gangs in the United States

Approximately 1.4 million people in the United States were part of gangs as of 2011, and more than 33,000 gangs were active in the country. These include national street gangs, local street gangs, prison gangs, outlaw motorcycle clubs, and ethnic and organized crime gangs.

Many American gangs began, and still exist, in urban areas. In many cases, national street gangs originated in major cities such as New York City and Chicago but they later grew in other American cities like Albuquerque and Washington, D.C.
