Data include children under age 18 arrested for violent crimes during the calendar year.  Violent crimes include: (a) homicide, (b) rape, (c) robbery, and (d) aggravated assault. Data do not include arrests made by tribal authorities of American Indian youth.

Arrest information is collected for all Part I and Part II offenses according to the age, sex, race, and ethnic origin of the offender. It is not possible, however, to correlate race or ethnic origin with the sex of the offender or specific ages because the information is collected independently, thus limiting analysis. Furthermore, arrest figures cannot be directly related to the number of crimes cleared because arrest totals count all the offenders who have been arrested even if several were involved in the commission of a single offense. Therefore, arrest and clearance totals will only be equal by coincidence.
It should be kept in mind that arrest totals do not indicate the number of different offenders involved in the commission of a crime. A total of four arrests may represent the arrest of four different offenders or the arrest of the same offender on four different occasions. Also, arrest totals do not indicate the number of charges placed against an offender at the time of the arrest.

Rate is arrests per 1,000 youth ages 8-17
Scoring of Offenses: Only the number of those offenses for Part I crimes and simple assault are scored (counted) under the Uniform Crime Reporting program. The method of scoring offenses varies with the type of crime committed, and it is important to remember that the number of offenders does not determine the number of offenses.

For murder and non-negligent manslaughter, negligent manslaughter, forcible rape, aggravated assault and simple assault, one offense is scored for each victim, regardless of the number of offenders involved. For example, two offenders could be involved in the murder of one victim and in this case only one murder would be scored.

For robbery and larceny-theft, one offense is scored for each distinct operation which is separate in time and place. The number of victims in any one operation does not determine the number of offenses. For example, if seven patrons in a bar are robbed, only one robbery would be counted. However, if the offender then leaves the bar and robs a passer-by, a second offense would be counted.

 For burglary, one offense is scored for each structure which is illegally entered. For UCR purposes, a structure is generally defined as an enclosed, permanently occupied area. However, when the structure is an apartment complex, business or office building in which units are leased for a period of time, one offense is counted for each unit burglarized. The illegal entry of those structures used for the housing of a transient population such as hotel rooms or boarding houses are scored as one burglary regardless of the number of rooms entered. For motor vehicle theft, one offense is scored for each vehicle stolen. For UCR purposes, a motor vehicle is defined as a self-propelled vehicle that runs on land and not rails. For arson, one offense is scored for each occurrence even if a more
serious offense occurred as the result of the arson. Additionally, any attempts to commit any of the above offenses are also counted under the appropriate offense category with the exception of attempted murder which is listed under aggravated assault.
