work to interrupt its transmission among community members. These public health-centered initiatives use street outreach workers to build relationships with high-risk individuals in their communities and connect them with intensive counseling, mediation, peer support, and social services in order to reduce their risk of violence. Evaluations have found that these programs are associated with significant reductions in gun violence, with some sites reporting up to 70-percent reductions in homicides or assaults. (C) Strategies, including group violence interventions (referred to in this section as GVI ), which are a form of problem-oriented policing that provides targeted social services and support to individuals at highest risk for involvement in community violence, and a process for community members to voice a clear demand for the violence to stop. This approach coordinates law enforcement, service providers, and community engagement efforts to reduce violence among a small, identifiable segment of the population that is responsible for the vast majority of gun violence in most cities. In one evaluation of the GVI program in Boston, researchers found a 63-percent reduction in youth homicides and a 25-percent decline in monthly gun assaults across the city. Other studies have found that GVI programs were associated with homicide reductions of up to 60 percent. (10) These strategies are often most effective when local officials and dedicated staff work to coordinate stakeholders, relevant public agencies, and service providers. Mayors in cities like Los Angeles and New York have established city departments that are primarily dedicated to violence prevention, and their offices have played a critical role in ensuring cross-agency collaboration and information sharing. (11) These strategies are also most effective when they receive consistent funding. For example, large cuts in funding for violence prevention programs in Chicago in 2008, 2012, and 2015 through 2016 corresponded with large spikes in homicides in
