"Admissions of young people aged 12 to 17 to remand, as well as sentenced custody and probation, fell for the second consecutive year following the enactment of the Youth Criminal Justice Act (YCJA) on April 1, 2003.
This decline in admissions coincides with decreases in both the youth crime rate and the youth incarceration rate."
