Definitions: The number of arrests of youth under age 18 for total crimes, violent crimes (like aggravated assault, murder, or forcible rape), property crimes (like larceny, arson, and motor vehicle theft), drug and alcohol offenses, and other crimes based on the National Incident Based Reporting System (NIBRS). Rates represent number of juvenile arrests per 1,000 juvenile population ages 10 through 17.

Data Source: Data for this measure come from the Washington State Governor's Juvenile Justice Advisory Committee (GJJAC) Juvenile Justice Reports. The report notes that GJJAC obtained these arrest data from Washington Uniform Crime Reporting (WUCR) program of the Washington Association of Sheriffs and Police Chiefs. 

Data are available online at https://www.dshs.wa.gov/ra/office-juvenile-justice/washington-state-juvenile-justice-annual-report

S: Data estimate has been suppressed. Data are suppressed when annual number of arrests was 10 or fewer.

Footnotes: Data last updated in May 2016 by Washington KIDS COUNT. 

Arrest rates are based on the population of juveniles age 10 through 17. However, juvenile arrest counts (numerator) include children under 10. The number of arrests does not represent every juvenile arrest made during the year, but reflects the information that was reported. Therefore, underreporting is likely. According to GJJAC, these numbers have not been adjusted by subtracting the population of police jurisdictions that did not report arrest data to Washington Uniform Crime Reporting. The arrest data do not include runaways or curfew violators reported to WUCR by individual agencies.

Starting in 2012, the Washington Association of Sheriffs and Police Chiefs (WASPC) began reporting using National Incident-Based Reporting System (NIBRS), replacing the UCR system. The methodologies differ significantly and therefore comparison between the two is not recommended.
