Definition
Juvenile detention is the temporary and secure custody of juveniles under the jurisdiction of the
Juvenile Court who require a restricted environment for their own protection and the safety of
the community. Responsibility for maintaining a juvenile detention center that is separate and
apart from an adult jail or lockup is vested with the counties.
In Arizona, a juvenile may be detained for the following reasons:
1. If there is probable cause to believe that the juvenile committed the acts alleged in the
petition, and there is reasonable cause to believe:
a. That otherwise the juvenile would not be present at any hearing;
b. That the juvenile is likely to commit an offense injurious to himself or others;
c. That the juvenile must be held for another jurisdiction; or
d. That the interests of the juvenile or the public require custodial protection.
2. As a condition of probation.
Thirteen of the fifteen counties in Arizona maintain a juvenile secure care facility. Juveniles
from two counties are transported to other jurisdictions when the need for secure custody is
determined by the Court. These juveniles appear in their county’s data as well as in the data of
the county in which they were detained. Additionally, some counties have entered into contracts
and/or agreements with federal agencies, tribal cour ts, or other state agencies to house juveniles.
These juveniles are reflected in the data that follows.
FY__ - Fiscal Year and the last two digits of the year. Each fiscal year starts on July 1st and ends on June 30th. The year on which it ends defines the FY reported here. e.g. July 1, 1999 to June 30, 2000 is Fiscal Year 2000 or FY00
Rates are per 1,000 youth ages 8-17

Arizona's Juvenile Court Counts, Juveniles Processed in AZ Court System FY00-FY12
Arizona's Juvenile Court Counts provides an overview of the juveniles processed at various stages of the juvenile justice system statewide during each fiscal year. The data for this report are drawn from the fifteen Juvenile Courts' Juvenile On-Line Tracking System (JOLTS). Selected breakdowns of an unduplicated juvenile count are presented at the following stages: Referral; Diversion; Petition; Dispositions of Dismissed; Penalty Only; Standard Probation; Juvenile Intensive Probation Supervision; Gender, Arizona Department of Juvenile Corrections; Direct Filed in and Transferred to Adult Court; and Juveniles Detained.

Beginning in 2018
U.S. Census Bureau, American Community Survey Table B09001 Population under 18 years of age is used to calculate rates.
Prior to July 25, 2013
Population estimates used to determine the rates for 2003 were calculated by taking the percentage of 8-17 year olds in each county according to the 2000 Census Table QTP-2 and multiplying that percentage by the population estimates for 2003 found in Table 1: Annual Estimates of the Population for Counties of Arizona: April 1, 2000 to July 1, 2003 (CO-EST2003-01-04) from the US Census Bureau, Population Division.
After July 25, 2013
Population estimates were taken from the Central for Disease Control and Prevention, National Vital Statistics System, July 1, 2000-July 2009 Revised Bridged-Race Intercensal Population Estimates and Vintage 2012 Bridged-Race Postcensal Population Estimates
These population estimates were used to recalculate the rates for years 2002-2012, because they are broken down by single year of age and thus provided a more accurate estimate of the 8-17 year old population in each county.
