- Definition: Estimated percentage of public school students in grades 7, 9, 11, and non-traditional programs who consider themselves gang members, by race/ethnicity (e.g., in 2015-2017, an estimated 5.1% of Hispanic/Latino students in grades 7, 9, 11, and non-traditional programs in California considered themselves gang members).
- Data Source: WestEd, California Healthy Kids Survey (CHKS) and Biennial State CHKS. California Dept. of Education (Mar. 2019).
- Footnote: “Gang” is not defined in the survey, so use caution when interpreting these data. Years presented comprise two school years (e.g., 2015-16 and 2016-17 school years are shown as 2015-2017). County- and state-level data are weighted estimates; school district-level data are unweighted. Students in non-traditional programs are those enrolled in community day schools or continuation education. The notation S refers to (a) data for school districts that have been suppressed because there were fewer than 10 respondents in that group, and (b) data for counties that have been suppressed because the sample was too small to be representative. N/A means that data are not available.

- Measures of Gang Involvement on Kidsdata.org
-
On kidsdata.org, indicators of gang involvement come from the California Healthy Kids Survey (CHKS) and California School Staff Survey (CSSS); data are based on:
- Student reports of gang membership by grade level (7th, 9th, 11th, and non-traditional programs), gender, level of school connectedness,* parent education level, race/ethnicity, and sexual orientation
- School staff reports of the extent to which, at their school (elementary, middle, high, or non-traditional), student gang activity is a problem
“Gang” is not defined in CHKS or CSSS, so use caution when interpreting these data.
State-level CHKS estimates, although derived from the Biennial State CHKS, may differ from data published in Biennial State CHKS reports due to differences in grade-level classification of students in continuation high schools.
*Levels of school connectedness are based on a scale created from responses to five questions about feeling safe, close to people, and a part of school, being happy at school, and about teachers treating students fairly. -

While youth involved in gangs comprise only a small portion of the adolescent population, gang membership is a significant threat to youth health and well being in the U.S. (1). The majority of youth who join gangs do so between the ages of 11 and 15, and nearly one in five students in grades 6 to 12 report that their school has gangs (1). Gang members are responsible for the majority of serious violence committed by youth, and they are more likely to bring weapons to school than other youth (2). Youth involved in gangs also are more likely to drop out of school, abuse substances, engage in high risk sexual behavior, and experience employment instability (1).
The effects of gang activity extend beyond the individuals involved. For example, when youth are exposed to violence or feel unsafe at school, it can negatively affect their health and well being as well as their academic performance (2, 3). Communities also can be affected in terms of reduced quality of life, increased crime, families moving out of neighborhoods, and economic costs, e.g., losses in property values, local businesses, and tax revenue (1).For more information on student gang involvement, see kidsdata.org’s Research & Links section.

In 2015-2017, fewer than 1 in 20 California 7th, 9th, and 11th graders considered themselves gang members, down from more than 1 in 15 in 2011-2013. Students in non-traditional programs, students with lower levels of school connectedness, male students, and students whose parents had lower levels of education were more likely to be involved with gangs than their peers in other groups. Asian youth had the lowest rates of gang involvement (4%) among racial/ethnic groups with data in 2015-2017, while African American/black youth had the highest (8%). Reports of gang membership also tended to be lower for straight students in comparison with students who identified as gay, lesbian, or bisexual, and those unsure of their sexual orientation.
School staff reports from 2015-2017 show that gang-related activity was a moderate or severe problem according to 2% of responses by elementary school staff, 9% of responses by middle school staff, 13% of responses by high school staff, and 31% of responses by non-traditional program staff statewide. - Policy Implications
-
Policymakers across the state and nation are taking action to combat youth gang activity. The most effective approaches go beyond law enforcement and gang suppression to comprehensive prevention strategies that address individual, family, school, and community risk factors associated with gang involvement (1, 2). Early prevention is critical, as most youth who join gangs become members between ages 11 and 15 (1).
Policy options that could prevent gang involvement include:
- Supporting evidence-based programs that strengthen parenting, family support, and family functioning (e.g., warm family bonds, consistent child supervision and discipline, and strong social networks), including early prevention programs that provide support to low-income pregnant mothers and families with young children (1, 2, 4)
- Ensuring that schools assess gang problems and engage families and community partners to create safe, supportive school climates, which are linked to lower rates of violence, improved academic performance, and other positive outcomes (1, 3, 4)
- Supporting school-wide programs that help all students build social-emotional skills, such as problem solving and conflict resolution skills (1, 3, 4)
- Promoting implementation of non-punitive school discipline policies that are clear, fair, consistent, and promote a positive learning environment; such policies should be based on a tiered system of appropriate responses to misconduct that keep students in school when possible and should include clear, equitable classroom behavior management practices (2, 3)
- Supporting coordinated community efforts to build on neighborhood strengths and provide youth with positive, supervised activities, such as tutoring, mentoring, after-school programs, life-skills training, and recreational activities (1, 2, 4)
- Implementing evidence-based, data-driven, comprehensive gang intervention strategies tailored to community needs and based on cross-sector community partnerships operating in concert with law enforcement; these should include prevention, intervention, and suppression efforts that are carefully developed, implemented, and evaluated (1, 2, 4)
