As gang violence increases from San Clemente to La Habra, gangs have become a growing concern throughout Orange County and a Priority for police and the district attorney's office. Gangs of all kinds operate within the county. Some are so-called "territorial" or "turf" gangs, whose members believe they control specific areas; others are considered "nomadic," operating in various places in he county with no special turf. Some are considered violent; some are not. As part of the county's anti-gang efforts, the district attorney's office recently made public this map, which shows the turf claimed by 164 "territorial" gangs, as of March, 1992. Other law enforcement agencies released the names of 111 other gangs, some of which are "nomadic" because they operate throughout the county with no specific geographic base. The shaded areas merely represent turf claimed by gangs, and do not reflect their relative safety for ordinary citizens, or the amount of gang crime committed there. The map is produced by the district attorney's office with help of all 27 police agencies in the county, and is updated regularly as an aid to police investigators and as "a graphic illustration of the growth of gangs in Orange County," according to the district attorney's latest annual report on gangs.
