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.

In 2023, the youth violent crime severity index value in Canada increased by three points (+3.61 percent) since 2022. In total, the crime severity index amounted to 86.18 points in 2023.

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.

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 data, by region, contains:

• the number of violations under the Youth Criminal Justice Act
• child pornography
• sexual violations against children
• luring a child via a computer
• making sexually explicit material available to children

The survey was designed to measure the incidence of crime in our society and its characteristics.

The Canadian Centre for Justice Statistics, in co-operation with the policing community, collects police-reported crime statistics through the UCR survey.

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.

These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. Teenage adolescent females residing in Baltimore, Maryland who were involved in a relationship with a history of violence were sought after to participate in this research study. Respondents were interviewed and then followed through daily diary entries for several months. The aim of the research was to understand the context regarding teen dating violence (TDV). Prior research on relationship context has not focused on minority populations; therefore, the focus of this project was urban, predominantly African American females. The available data in this collection includes three SAS (.sas7bdat) files and a single SAS formats file that contains variable and value label information for all three data files. The three data files are: final_baseline.sas7bdat (157 cases / 252 variables) final_partnergrid.sas7bdat (156 cases / 76 variables) hart_final_sas7bdata (7004 cases / 23 variables)

A survey of high school students in the United States found that around 13.6 percent of students experienced teen dating violence in 2021. When broken down into race and ethnicity, around 14.9 percent of white students reported teen dating violence, and 7.2 percent of Asian students.

Incident-based crime statistics (actual incidents, rate per 100,000 population, percentage change in rate, unfounded incidents, percent unfounded, total cleared, cleared by charge, cleared otherwise, persons charged, adults charged, youth charged / not charged), by detailed violations (violent, property, traffic, drugs, other Federal Statutes), police services in the Atlantic provinces (Newfoundland and Labrador, Prince Edward Island, Nova Scotia, New Brunswick), 1998 to 2023.

The dataset includes crime statistics from law enforcement agencies operating in Nova Scotia. It is based on police-reported incidents of crime reported through the national Uniform Crime Reporting Survey (UCR). Statistics include the Crime Severity Index (CSI), the Violent Crime Severity Index (VCSI), and the Non-violent Crime Severity Index (NVCSI). Data source: Statistics Canada.

The research project is a subproject of the research association “Strengthening of integration potentials within a modern society” (Scientific head: Prof. Dr. Wilhelm Heitmeyer, Bielefeld) which contains 17 subprojects and is supported by the ministry of education and research.
In almost all the economically highly developed countries violent crime increased significantly in the second part of the last century - in contrast to the long term trend of decline of individual (non-governmental) violence since the beginning of modern times. The authors develop an explanatory approach for these facts which is inspired mainly by Norbert Elias´s civilization theory and Emil Durkheim´s theory on society. Detailed time series on the development of different forms of violent crime are presented and set in relation with certain aspects of economic and social structural changes in three countries and also refer to the changes in integration of modern societies. The analysis deals especially with effectivity and legitimacy of the governmental monopoly of violence, the public beneficial security and power system, forms of building social capital, economic and social inequality, precarity of employment, different aspects of increasing economization of society, changes in family structures and usage of mass media and modern communication technologies.

The National Survey of Teen Relationships and Intimate Violence (STRiV) examines the changing nature of adolescent dating relationships, particularly those marked by adolescent relationship abuse (ARA). More specifically, this study was designed to produce nationally representative estimates of the prevalence of multiple forms of ARA among youth (ages 10-18), to document the characteristics of abusive relationships during adolescence, to assess ARA risk factors, and to situate these estimates within the environment of adolescents' key social relationships and communications. STRiV includes individual data from a nationally representative sample of households with at least one resident youth. Baseline and follow-up surveys were completed using a secure web survey with toll-free telephone and online help available.

In 2023, the youth crime severity index value in Canada increased by 3.3 points (+6.55 percent) since 2022. In total, the crime severity index amounted to 53.74 points in 2023.

In response to a growing concern about hate crimes, the United States Congress enacted the Hate Crime Statistics Act of 1990. The Act requires the attorney general to establish guidelines and collect, as part of the Uniform Crime Reporting (UCR) Program, data "about crimes that manifest evidence of prejudice based on race, religion, sexual orientation, or ethnicity, including where appropriate the crimes of murder and non-negligent manslaughter, forcible rape, aggravated assault, simple assault, intimidation, arson, and destruction, damage or vandalism of property." Hate crime data collection was required by the Act to begin in calendar year 1990 and to continue for four successive years. In September 1994, the Violent Crime Control and Law Enforcement Act amended the Hate Crime Statistics Act to add disabilities, both physical and mental, as factors that could be considered a basis for hate crimes. Although the Act originally mandated data collection for five years, the Church Arson Prevention Act of 1996 amended the collection duration "for each calendar year," making hate crime statistics a permanent addition to the UCR program. As with the other UCR data, law enforcement agencies contribute reports either directly or through their state reporting programs. Information contained in the data includes number of victims and offenders involved in each hate crime incident, type of victims, bias motivation, offense type, and location type.

The What Worked? Policy Mobility and the Public Health Approach to Youth Violence study sought to further the ESRC's strategic objective of a 'safer, fairer society' through establishing a new evidence-base on public health approaches to violence reduction, and the ways such policies transfer between jurisdictions, to shape policy, guide best practice, and inform academic and public debate. Its main aim was to respond to the urgent social problem of rising youth violence. England and Wales have seen marked increases in homicide, knife crime, and hospital admissions for stab wounds, with particular concentrations in the city of London. Cressida Dick, when Commissioner of the Metropolitan Police, stated that tackling youth violence was her 'number one priority.'

In March 2019, UK Prime Minister Theresa May unveiled a consultation on a new public health strategy for youth violence. This approach, which seeks to address violence using principles of prevention and education rather than policing and justice, marks a major step-change in policy. The interest in developing this approach stems primarily from Scotland, where radical reductions in violent crime over the last decade have been attributed to the adoption of a public health model. There was however a lack of clear understanding of 'what worked' in the Scottish context. While there have indeed been marked declines in youth violence, the mechanisms that have driven this decrease are poorly understood. There is confusion over what public health approaches are, how they work, and the conditions under which such ideas can travel. As a result, despite significant potential, the implications of the public health approach remain vague.

This study was delivered in a three work-streams approach, over a three-year period:

1. What Worked
Through interviews with elite actors/professionals - senior police, politicians, and civil servants - the research team aimed to establish an expert appraisal of the causes of violence reduction in Scotland. This was complemented by a detailed documentary analysis, investigating the social, political, and cultural conditions in which violence reduction occurred, and a series of 20 semi-structured interviews with practitioners and residents of communities affected by violence to establish a 'bottom-up' account of change. Finally, available statistical data on violence and health was leveraged to triangulate explanations. These data sources were combined to produce a policy briefing, two journal articles, and a short film on the theme of 'what worked'.

2. Policy Travels
Using flexible and responsive ethnographic methods, the research team aimed to track the evolution of the public health approach in London as it evolved in real-time, entering the 'assumptive worlds' of policy through attendance at key meetings and events. Observations were complemented by a series of semi-structured interviews with elite actors engaged in violence reduction in London, and 20 semi-structured interviews with residents and youth practitioners, exploring the factors that promote or impede change. Mirroring data-collection in Scotland, relevant statistical data was used to evaluate the extent to which policy changes are impacting on violence reduction. These data were used to produce a second policy briefing, two journal articles, and a series of podcasts on 'how ideas travel'.

3. Connecting Communities
Data from these work-streams will be connected via an open access data set to enhance understanding of best practice in violence reduction. Data will be analysed and published as an academic monograph aimed at scholars working in the areas of criminology, public health and social policy. Through our advisory group and engagement with policy user-groups, the research team will engage directly with policy actors at the highest level, and using cooperative methods will create a practitioner toolkit. Communities of policy, practice and public will be connected through a website, a series of events and a roadshow.
