Youth Perpetrators of Serious Violent Crimes

Youth who commit violent crimes tend to exhibit multiple problematic behaviors that affect their well-being, including drug use, risky sexual behaviors, and problems in school.99 One measure of youth violence is the rate of serious violent crimes committed by juveniles. Because insufficient data exist to determine the ages of each individual offender when a crime is committed by more than one perpetrator, the number of additional juvenile offenders cannot be determined. Therefore, this rate of serious violent crime offending does not represent the number of juvenile offenders in the population but rather the rate of crimes perpetrated by a juvenile.

Indicator BEH5.A: Rate of serious violent crimes by youth perpetrators ages 12–17, 2005–2021
Indicator BEH5.A: Rate of serious violent crimes by youth perpetrators ages 12–17, 2005–2021

NOTE: The rate is the ratio of the number of crimes (aggravated assault; rape; and robbery, i.e., stealing by force or threat of violence) reported to the National Crime Victimization Survey that involved at least one offender perceived by the victim to be ages 12–17, plus the number of homicides reported to the police that involved at least one known juvenile offender, to the number of juveniles in the population. In 2021, homicides represented 1.2% of serious violent crime, and the total number of homicides by juveniles has been relatively stable over the last decade. Beginning in 2021, the number of homicides were estimated using the FBI's National Incident-Based Reporting System. From 1993-2020, the number of homicides were estimated using the FBI's Supplementary Homicide Reports. See Criminal Victimization, 2006 (https://www.bjs.gov/index.cfm?ty=pbdetail&iid=765) for more information on the redesigned methodology. Due to methodological changes, use caution when comparing 2006 estimates to other years. Estimates for 2016 are not included because, in 2016, the National Crime Victimization Survey sample was redesigned, so 2016 estimates among youth are not comparable with estimates from other years. In 2020, historical estimates were revised since previous publication in America's Children due to changes in the methodology for calculating offender totals for youth and revisions to homicide numbers. The 2020 NCVS weights include an additional adjustment to address the impact of modified field operations due to COVID-19. For more information on the weighting adjustments applied in 2020, see the Source and Accuracy Statement for the 2020 National Crime Victimization Survey in the NCVS 2020 Codebook (https://www.icpsr.umich.edu/web/NACJD/studies/38090/summary) and Criminal Victimization, 2020 (NCJ 301775, BJS, October 2021).

  • In 2021, the serious violent crime offending rate was 5 crimes per 1,000 juveniles ages 12–17, with a total of 122,900 such crimes involving juveniles. This rate was not significantly different from the rate in 2020 or 2019.
  • The violent crime offending rate declined 70% from 17 crimes per 1,000 juveniles ages 12–17 in 2005 to 5 crimes per 1,000 in 2021.
  • In 49% of all youth-perpetrated serious violent crimes reported by victims in 2021, more than one offender was involved in the incident.
