In 2021, there were about 123,000 serious violent crimes committed by youths between the ages of 12 and 17 in the United States, an increase from the year before. However, this is still a significant decrease from 1994 levels, when violent crimes committed by youths hit a peak at over 1.05 million serious crimes.

Youth and crime

According to the most recent data, criminal youths in the United States continue to participate in violent crimes each year. In 2022, there were over 1,000 murder offenders between the ages of 13 and 16 in the United States. Studies have also shown that crimes are reported against children at U.S. schools, with students aged between 12 and 14 years found more likely to be victims of violent crime and theft. However, the number of adolescent violent crime victims in the U.S. far surpasses the number of adolescent perpetrators. The number of adolescent victims has also declined significantly since the early 1990s, following the national downward trend of violent crime.

Overall downward trends

There is not only a downward trend in the number of violent crimes committed by youths, but also in the share of crimes involving youths. On a national level, the crime rate has also decreased in almost every state, showing that the country is becoming safer as a whole.

In 2021, around 9.7 percent of serious violent crime cases in the United States involved teenagers, an increase from the previous year, where 7.5 percent of serious violent crimes involved teenagers. The share of serious violent crimes involving children between 12 and 17 years old reached a peak in 1994, at 25.1 percent.

The research team collected data on homicide, robbery, and assault offending from 1984-2006 for youth 13 to 24 years of age in 91 of the 100 largest cities in the United States (based on the 1980 Census) from various existing data sources. Data on youth homicide perpetration were acquired from the Supplementary Homicide Reports (SHR) and data on nonlethal youth violence (robbery and assault) were obtained from the Uniform Crime Reports (UCR). Annual homicide, robbery, and assault arrest rates per 100,000 age-specific populations (i.e., 13 to 17 and 18 to 24 year olds) were calculated by year for each city in the study. Data on city characteristics were derived from several sources including the County and City Data Books, SHR, and the Vital Statistics Multiple Cause of Death File. The research team constructed a dataset representing lethal and nonlethal offending at the city level for 91 cities over the 23-year period from 1984 to 2006, resulting in 2,093 city year observations.

This project examined the role of technology use in teen dating violence and abuse, and bullying. The goal of the project was to expand knowledge about the types of abuse experiences youth have, the extent of victimization and perpetration via technology and new media (e.g., social networking sites, texting on cellular phones), and how the experience of such cyber abuse within teen dating relationships or through bullying relates to other life factors. This project carried out a multi-state study of teen dating violence and abuse, and bullying, the main component of which included a survey of youth from ten schools in five school districts in New Jersey, New York, and Pennsylvania, gathering information from 5,647 youth about their experiences. The study employed a cross-sectional, survey research design, collecting data via a paper-pencil survey. The survey targeted all youth who attended school on a single day and achieved an 84 percent response rate.

Youth violence is violence or aggression perpetuated by or targeted against youth and includes many forms such as violent crime, physical violence (e.g., fighting, use of firearms), and the numerous manifestations of bullying (e.g., overt, social/relational, and cyber bullying). New research is needed to enhance our understanding of the factors and processes associated with youth violence. This research focuses on key factors within individuals and multiple contexts that may robustly predict the perpetration and amelioration of violence among youth but that have received scant attention in previous research, especially in concert with each other. Specifically, the factors within individuals the investigators examined include cognition (e.g., attitudes towards retaliation and bystander intervention) and social-emotional adjustment (e.g., rejection sensitivity, affect, aggressive behavior and victimization) while the multiple contexts will include peer (e.g., characteristics and status of peer group, sociometric and perceived popularity), school (e.g., school connectedness, student-teacher relationship), and family contexts (e.g., attachment, family hostility). This dataset seeks to aid scholars hoping to understand adolescents' attitudes and judgments surrounding peer aggression, with attention both to attitudes surrounding bystander intervention to stop aggression and retaliation when exposed to such aggression. This project is a year-long longitudinal study with 6th graders and 9th graders in order to identify factors related to responses to peer aggression and to examine these relations over time.

The purpose of this study was to assess both the school-level effects and the participant-level effects of Youth Crime Watch (YCW) programs. Abt Associates conducted a four-year impact evaluation of Youth Crime Watch (YCW) programs in three Florida school districts (Broward, Hillsborough, and Pinellas Counties). School-based YCW programs implement one or more of a variety of crime prevention activities, including youth patrol, in which YCW participants patrol their school campus and report misconduct and crime. The evaluation collected both School-Level Data (Part 1) and Student-Level Data (Part 2). The School-Level Data (Part 1) contain 9 years of data on 172 schools in the Broward, Hillsborough, and Pinellas school districts, beginning in the 1997-1998 school year and continuing through the 2005-2006 school year. A total of 103 middle schools and 69 high schools were included, yielding a total of 1,548 observations. These data provide panel data on reported incidents of crime and violence, major disciplinary actions, and school climate data across schools and over time. The Student-Level Data (Part 2) were collected between 2004 and 2007 and are comprised of two major components: (1) self-reported youth attitude and school activities survey data that were administered to a sample of students in middle schools in the Broward, Hillsborough, and Pinellas School Districts as part of a participant impact analysis, and (2) self-reported youth attitude and school activities survey data that were administered to a sample of YCW continuing middle school students and YCW high school students in the same three school districts as part of a process analysis. For Part 2, a total of 3,386 completed surveys were collected by the project staff including 1,319 "new YCW" student surveys, 1,581 "non-YCW" student surveys, and 486 "Pro" or "Process" student surveys. The 138 variables in the School-Level Data (Part 1) include Youth Crime Watch (YCW) program data, measures of crime and the level of school safety in a school, and other school characteristics. The 99 variables in the Student-Level Data (Part 2) include two groups of questions for assessing participant impact: (1) how the respondents felt about themselves, and (2) whether the respondent would report certain types of problems or crimes that they observed at the school. Part 2 also includes administrative variables and demographic/background information. Other variables in Part 2 pertain to the respondent's involvement in school-based extracurricular activities, involvement in community activities, attitudes toward school, attitudes about home environment, future education plans, attitudes toward the YCW advisor, attitudes about effects of YCW, participation in YCW, reasons for joining YCW, and reasons for remaining in YCW.

The Jewish Autonomous Oblast and the Republic of Karelia in Russia were the country's federal subjects with the largest share of crimes committed by underage persons or where they acted as co-perpetrators in 2024. Furthermore, in the Tyva Republic, criminal cases involving youth accounted for 5.6 percent of the total.
