Street Gangs - Types and Structure

Types and Structure

Many types of gangs make up the general structure of an organized group.

There are street gangs, which are people with similar backgrounds and motivations. The term “street gang” is commonly used interchangeably with “youth gang,” referring to neighborhood or street-based youth groups that meet “gang” criteria. Miller (1992) defines a street gang as “a self-formed association of peers, united by mutual interests, with identifiable leadership and internal organization, who act collectively or as individuals to achieve specific purposes, including the conduct of illegal activity and control of a particular territory, facility, or enterprise."

Understanding the structure of gangs is a critical skill to defining the types of strategies that are most effective with dealing with them, from the at-risk youth to the gang leaders. Not all individuals who display the outward signs of gang membership are actually involved in criminal activities. An individual's age, physical structure, ability to fight, willingness to use violence, and arrest record are often principal factors in determining where an individual stands in the gang hierarchy; now money derived from criminal activity and ability to provide for the gang also impacts the individual’s status within the gang. The structure of gangs varies depending primarily on size which can range in size from five or ten to several thousand. Many of the larger gangs break up into smaller groups, cliques or sub-sets. The cliques typically bring more territory to a gang as they expand and recruit new members. Most gangs operate informally with leadership falling to whoever takes control; others have distinct leadership and are highly structured, much like a business or corporation.

Matthew O’Deane, Ph.D., has identified five primary steps of gang involvement applicable to the majority of gangs in the world; at risk, associates, members, hardcore members and leaders.
