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.

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 dataset includes incident-based crime statistics at the provincial level. Statistics included in the dataset are the number of youth charged or not charged, and rates per 100,000 youth population for total Criminal Code violations (excluding traffic), total violent Criminal Code violations, total property crime violations, and total other Criminal Code violations. Data source: Statistics Canada.

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 number of persons aged 10 to 17 arrested for drug-related offenses per 1,000 juveniles that live in an area. Drug-related offenses include arrests for possession, sale, manufacture, or abuse of illegal drugs, including alcohol. This indicator is calculated by where the arrested juvenile was arrested and not by where the crime is committed. Arrests are used instead of crimes committed since not all juveniles that are arrested are charged with committing a crime. This indicator also excludes offenders who are later charged as adults for their crime(s). Source: Baltimore Police Department Years Available: 2011, 2012, 2013, 2014, 2015

This fact sheet summarizes the latest available data on measures of police-reported youth crime from Statistics Canada’s Uniform Crime Reporting (UCR) Survey, which collects information on criminal incidents that have been reported to police services in Canada.

The data contains the number of criminal incidents, the clearance status of those incidents and persons-charged, by MCYS region (Central, East, North, Toronto, West, Other). 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 dataset was compiled by the Illinois Criminal Justice Information Authority (ICJIA) at the request of the Governor’s Children’s Cabinet. This data contains the population of youth ages 13-26 in each county, the total population of each county, and the number and rate of index crimes reported, with domestic violence offenses and rates reported separately for every year between 2006 and 2015.

For the purpose of this analysis the crime data was gathered from the Illinois State Police Annual report Crime in Illinois. This publication is produced by the Illinois State Police every year using the UCR data that is submitted to them by individual jurisdictions throughout the state. The accuracy of this data presented is dependent on the local jurisdictions reporting their index crime and domestic violence offenses to ISP, so it can be included in the annual report.

Therefore, if there is large decrease in number of index crimes reported in the dataset it is likely that one or more jurisdictions did not report data for that year to ISP. If there is a large increase from year to year within a county it is likely that a jurisdiction within the county, who previously had not reported crime data, did report crime data for that year. If there is no reported crime in a certain year that means no jurisdictions, or a small jurisdiction with no crime from that county reported data to the Illinois State Police. The annual Crime in Illinois reports can be found on the ISP website www.isp.state.il.us.

A direct link to that annual reports is: http://www.isp.state.il.us/crime/ucrhome.cfm#anlrpts.

The Illinois Criminal Justice Information Authority did not record the data that is expressed in the dataset. ICJIA simply used the ISP reports to compile that yearly crime data into one chart that could be provided to the Illinois Governor’s Children’s Cabinet. This data set has be critically examined to be accurate according to the annual Crime in Illinois Reports. If there are issues with the data set provided please contact the Illinois State Police or the individual jurisdictions within a specific county.

**Index offenses do not include every crime event that occurs. Prior to 2014 there were 8 index crimes reported by the Illinois State Police in their annual reports, Criminal Homicide, Rape, Robbery, Aggravated Battery/Aggravated Assault, Burglary, Theft, Motor Vehicle Theft, and Arson. In 2014 there were two new offenses added to the list of index crimes these were Human Trafficking – Commercial Sex Acts and Human Trafficking – Involuntary Servitude. These are the index crimes that are recorded in the chart provided.

**“Domestic offenses are defined as offenses committed between family or household members.

Every offense that occurs, when a domestic relationship exists between the victim and offender, must be reported (Illinois State Police).”

**“Offenses reported are not limited to domestic battery and violations of orders of protection; offenses most commonly associated with domestic violence (Illinois State Police).”

The crime rate was compiled using the total population, and the index crime. The Index crime whether all crime or Domestic Violence crime was divided by the total population then multiplied by 10,000, hence crime rate per 10,000.
