Additional State Notes
Illinois did not provide a breakdown of probation data for either violation admissions or population. In Illinois, probation terms are not identified in prison data, as probation is run by the Administrative Office of the Courts (AOC). AOC indicated that they were unable to provide figures at this time. They are currently working on a way to make this type of analysis available in the future.
In addition to other parole sanction options reported, some people are eligible for pre-release electronic detention or partial release work release programs. In the case of some individuals who were convicted of a sex offense, parole admissions can include people who never exited the facility because they violated a parole rule that requires an approvable host site.
Technical parole violations may include people who ultimately receive a new felony conviction.
Whether an incarceration is the result of a new offense or technical violation is often difficult and problematic to delineate, even in states with available data. Most states do not consider a supervision violation to be the result of a new offense unless a new felony conviction is present, meaning technical violations may include misdemeanor convictions or new arrests. "Prison" includes county jail if the county was reimbursed by the state for a person’s incarceration, which occurs in some, but not all, states. Supervision violations may include revocations (i.e., unsuccessful terminations of a supervision and completion of a sentence in prison or jail) or short-term sanctions (i.e., probation or parole jurisdiction is maintained and the person is incarcerated for a short period of time in prison or jail). Not all states impose or include short-term sanctions in their count of supervision violations.
