The terms “youth gang” and “street gang” are commonly used interchangeably and refer to neighborhood or street-based youth groups that are substantially made up of individuals under the age of 24. While youth in this age group are most likely to be engaged in or at risk of committing serious or violent gang crimes, the OJJDP Comprehensive Gang Model focuses primarily on youth gang members less than 22 years of age, which is based on OJJDP’s authorizing legislation. Motorcycle gangs, prison gangs, ideological gangs, and hate groups comprised primarily of adults are excluded from the definition.
The Model holds that the lack of social opportunities available to this population and the degree of social disorganization present in a community largely account for its youth gang problem. The Model also suggests other contributing factors, including poverty, institutional racism, deficiencies in social policies, and a lack of or misdirected social controls. Drawing principally on social disorganization theory to frame the development of the Model, a team from the University of Chicago expected the core strategies of the Model to address gang youth, their families, and the community institutions that purport to promote their transition from adolescence to productive members of society. With this in mind, law enforcement and other agency personnel in 65 cities reporting problems with gangs were surveyed. Analysis of that information, in conjunction with site visits and focus groups, led to a mix of five strategies that address key concerns raised by the theory upon which the OJJDP Comprehensive Gang Model is based:
Community Mobilization: Involvement of local citizens (including former gang youth and community groups and agencies) and the coordination of programs and staff functions within and across agencies.
Provision of Opportunities: The development of a variety of specific education, training, and employment programs targeted at gang-involved youth.
Social Intervention: Youth-serving agencies, schools, grassroots groups, faith-based organizations, police, and other criminal justice organizations "reaching out" and acting as links between gang-involved youth (and their families) and the conventional world and its needed services.
Suppression: Formal and informal social control procedures, including close supervision or monitoring of gang youth by agencies of the criminal justice system and also by community-based agencies, schools, and grassroots groups.
Organizational Change and Development: Development and implementation of policies and procedures that result in the most effective use of available and potential resources within and across agencies to better address the gang problem.
These strategies were found to be present—to a lesser or greater degree—in the cities with identified gang problems that were having a positive impact on gangs. In addition to data from the surveys, extensive input from expert practitioners and gang researchers made it clear that a community’s gang violence problem required attention be paid to both gang-involved youth and gangs themselves. Long-term change would not be achieved without also addressing the institutions which support and control youth and their families.
The following program development process will facilitate implementation of the five core strategies:
-
Acknowledgment of the problem. The presence of a youth gang problem must be recognized before anything meaningful can be done to address it. If denial is present, it must be confronted.
-
Assessment of the problem. Those with responsibility for addressing the problem—representatives of police, schools, probation, youth agencies, grassroots organizations, government, and others—participate in identifying its nature and causes and recommending appropriate responses. The assessment results in an understanding of who is involved in gang crime and where in the community it is concentrated. This, in conjunction with other data and information, enables targeting of:
- Gang-involved youth.
- The most violent gangs.
- The area(s) where gang crime most often occurs.
-
Setting goals and objectives. Once the problem is described, goals and objectives based on the assessment findings are established. These should emphasize changes the Steering Committee wants to bring about in the target area.
-
Relevant services and activities. Rationales for services, tactics, and policies and procedures that involve each of the key agencies are articulated and then implemented for each of the five core strategies. These activities must be closely coordinated or integrated to ensure that the work of collaborating agencies is complementary. Representatives of those organizations that will have the most direct contact with the target youth—police, probation, schools, and youth workers—should form an Intervention Team and have regular meetings to share critical information, plan, and act collaboratively on individual youth and gang activity in the target area. Thus, the resources of collaborating agencies are focused on a group of young people who are involved in gangs and are most likely to be involved in gang-related violence.
It is important to remember that while youth gang members must be held accountable for their criminal acts, they also must be provided with services for their academic, economic, and social needs. Gang members must be encouraged to control their behavior and to participate in legitimate, mainstream activities. At the same time, external controls on gang and gang-member behavior must be exercised. For some gang members, secure confinement will be necessary. For others, graduated degrees of community-based supervision, ranging from continuous sight or electronic supervision to incarceration, will be appropriate. It is important that youth understand that they will face consequences if they do not follow rules, laws, conditions, or reasonable expectations of the program. It also may be important to develop a set of incentives for compliance with the program. Thus, a range of services and sanctions is required, often in some interactive way. To be effective in this approach, an understanding of how a youth’s family, peers, and others are involved is important.
This approach is very consistent with community policing, which promotes and supports organizational strategies to address and reduce the fear of crime and social disorder through problem-solving tactics and community/police partnerships. In this Model, gang unit, community policing, or other officers are involved in the problem-solving process at the street level while senior officers work with the policymakers.
The work of the collaborating agencies is overseen by a Steering Committee of policy or decision makers from agencies and organizations that have an interest in or responsibility for addressing the community’s gang problem. These representatives should not only set policy and oversee the overall direction of the gang program but should take responsibility for spearheading efforts in their own organizations to remove barriers to services and social and economic opportunities. They must also develop effective criminal justice, school, and social agency procedures and promote policies that will further the goals of the gang strategy.

Evaluation. Results from the evaluation of the Little Village Gang Violence Reduction Project show that the Model is effective in lowering crime rates among youth gang members (University of Chicago, 1999). Preliminary results from an evaluation of five communities chosen as demonstration sites for the Model show that a combination of intervention, suppression, and prevention strategies, along with a coordinated team approach to delivering services, have a positive impact on reducing gang crime. The incorporation of a strong evaluation component as the initiative is taking form and throughout the life of the program is critical to assessing the impact of the program.
In summary, The OJJDP Comprehensive Gang Model espouses a multifaceted, multilayered approach that includes eight critical elements:
- Initial and continuous problem assessment using qualitative and quantitative data.
- Targeting of the area and those populations of individuals most closely associated with the problem, as described in the assessment.
- Mix of the five key strategies: community mobilization, social intervention, opportunities provision, suppression, and organizational change/development.
- A Steering Committee to oversee and guide the project.
- Direct contact intervention team that includes police, probation, outreach staff, and others.
- A plan for coordinating efforts of and sharing appropriate information among those who work with the youth on a daily basis, the Steering Committee, and persons within the partner organizations.
- Community capacity building to sustain the project and address issues that are long-term in nature.
- Ongoing data collection and analysis to inform the process and evaluate its impact.
