In New York City, five major Italian-American Mafia families dominate organized crime activities: Bonnano crime family, Columbo crime family, Gambino crime family, Genovese crime family, and Luchese crime family. While the Mafia--also known as La Cosa Nostra--may no longer possess the robust national presence and influence it once had, it remains a significant threat in the extended New York metropolitan area, New England, Philadelphia, Chicago, and Detroit.
