Information is provided on offenders incarcerated in secure facilities, placed in community corrections programs, and supervised on parole. Data on juvenile offenders sentenced as adults to the Youthful Offender System (Y.O.S.) are reported in the final section. Offenders under CDOC jurisdiction increased to 26,440 from 25,068 in fiscal year 2003. This included 19,478 inmates, 6,722 offenders under parole supervision, and 240 offenders in the Y.O.S. The growth in the number of offenders under CDOC jurisdiction in recent years has exceeded the national trends, which have shown little or no increase. This report contains information on sentencing trends, technical prison returns, and lengths of stay for released offenders. The impact of recent sentencing changes, including the mandatory parole provisions in H.B. 93-1302, are evident in the admission and release sections of the report. Information is also provided on the sentencing of sex offenders pursuant to the lifetime supervision legislation enacted in 1998. Security-level definitions and designations for the correctional facilities operated by or under contract with the CDOC were changed in legislation enacted in 2000, and these changes are reflected throughout this report. Appendixes show the security levels and population of facilities and operational capacity by facility
