Additionally, the number of people impacted by county and city jails in Idaho is much larger than the graph above would suggest, because people cycle through local jails relatively quickly. Each year, at least 27,000 different people are booked into local jails in Idaho.
Today, Idaho’s incarceration rates stand out internationally
In the U.S., incarceration extends beyond prisons and local jails to include other systems of confinement. The U.S. and state incarceration rates in this graph include people held by these other parts of the justice system, so they may be slightly higher than the commonly reported incarceration rates that only include prisons and jails. Details on the data are available in States of Incarceration: The Global Context. We also have a version of this graph focusing on the incarceration of women.

We gave Idaho a failing grade in September 2021 for its response to the coronavirus in prisons, noting that:
- Idaho is one of only 8 states that have failed to reduce their prison population by more than 10% during the pandemic.
- Idaho is one of 13 states that did not explicitly mention incarcerated people in their vaccination rollout plan.
- Idaho is one of 13 states that did not implement any policies to accelerate releases, promote medical parole or compassionate release, prevent incarceration for technical violations of probation and parole, or hasten releases for people incarcerated on minor offenses.
