Additional State Notes

Data was provided by Montana's Justice Reinvestment Initiative Data Tracking Workbook.

Admissions and population due to supervision violations do not include "Alternative Offender" or "Condition Release" supervision violations.

Technical probation and 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.
