Vera Institute of Justice (Vera) researchers recently published some very interesting prison population data collected directly from state departments of corrections and the federal Bureau of Prisons (BOP). Oregon’s prison incarceration rate fell 0.7% since the last time records were collected. This decline is below average for the nation as a whole (where incarceration rates fell 1.8%) and my best guess is that this is a reflection of Oregon’s spectacular population growth. Looking at total numbers rather than rates, the trend is toward locking more and more people up. Here are some more interesting charts: https://www.prisonpolicy.org/profiles/OR.html
Half of those inmates have serious mental illnesses.
