This report presents juvenile (ages 10-17) reoffending data for those released from custody or beginning a non-custodial court disposition or out-of-court disposition in the first quarter of the cohort year (2009) in England and Wales.
A "re-offense" is defined as any offense committed in the 1-year follow-up period proven by a court conviction or an out-of-court disposition. A comparison of reoffending data for the 2000, 2008, and 2009 juvenile cohorts shows that since 2000, the number of re-offenses committed per 100 offenders (frequency rate) has fallen from 151.4 to 110.5, a 27-percent decline. Since 2008, the frequency rate has declined 3 percent. When controlling for changes in offender characteristics, the proportion of juvenile offenders who reoffended has decreased by 9.7 percent since 2000. Since 2000, the number of most serious re-offenses committed per 100 offenders (severity rate) has risen from 0.91 to 0.96, a 4.9-percent increase. Since 2008, it has increased 13.3 percent. Data for the 2009 cohort address the frequency and severity rates, the actual and predicted proportion of offenders who re-offended, re-offending across the 1-year follow-up period, and the number of offenders in the cohort. Offender data address gender, age, index offense group, previous offending history, index disposition, and ethnicity. Appendixes contain extensive statistical tables, a glossary of terms, the measurement of re-offending, a data-quality statement, statistical modeling, coefficients of the 2005 statistical model, a list of most serious offenses, and references.
