Bryan Stevenson Delivers Five Key Messages During 2013 Summit Closing Remarks

"That's going to make you tired, tired, tired," Ms. Rosa Parks once said to Bryan Stevenson, Founder and Executive Director of the Equal Justice Initiative (EJI). Along with Ms. Parks' words, Johnnie Carr's rejoinder in that conversation, "That's why you've got to be brave, brave, brave," is a message to all National Forum on Youth Violence Prevention cities to continue an exhausting, challenging, and worthy struggle.

Gang Prevention: An Overview of Research and Programs

Since the mid-20th century, gang violence in this country has become widespread—all 50 states and the District of Columbia report gang problems, and reports have increased for 5 of the past 7 years. Despite the steady growth in the number and size of gangs across the United States and the criminal behavior and violence they spawn, little is known about the dynamics that drive gangs and how to best combat their growth. For instance, no consensus exists on how gangs form, and few gang prevention programs have been rigorously evaluated.

Federal Data

Tracking gang statistics and trends can help to assess the demographics of gangs in the U.S., including age range, prevalence, location, and types of crime associated with gangs. This information can help to target prevention initiatives and interventions, and determine youth at risk for gang involvement.

Gang Activity and Violence

Although gang activity1 in the U.S. showed a decline in the mid 1990’s to 2000, it increased from 2001 to 2005 and has since remained constant. Over the past decade, annual estimates of the number of gangs have averaged about 25,000 nationally and the number of gang members has been about 750,000.2

  • In 2009, larger cities and suburban counties accounted for the majority of gang-related violence and more than 96 percent of all gang homicides.3
  • During 2009-2012, cities with 100,000 or more persons saw gang-related homicides increase by 13 percent.4
  • In Chicago and Los Angeles, nearly half of all homicides were attributed to gang violence from 2009-2012.5

Demographic Characteristics of Gang Members

  • Between 1998 and 2009, gang members were overwhelmingly male with less than ten percent of total gang members being female. Learn more about the involvement of girls in gangs and juvenile delinquency.  
  • While the majority of gang members are adults, as of 2008, two out every five gang members are under 18, as reported by law enforcement.6
  • The prevalence of youth under 18 in gangs is higher in smaller cities and rural communities where gang problems are less established, compared to larger cities.7
  • Between 1996 and 2008, gang members were more likely to be Hispanic/Latino and African-American/black than other race/ethnicities. Specifically they reported gang members were 50 percent Hispanic or Latino, 32 percent African American, 10 percent white, and 8 percent identifying as another race or ethnicity.8
