The United States has one of the highest incarceration rates in the world: Nearly 1 out of every 100 adults is in prison or jail, and 1 out of every 50 adults is on probation or parole.

The corrections field faces significant challenges. For one, the demographics of those incarcerated have changed in recent years. Today, the U.S. prison population is aging and includes both a greater proportion of women and more individuals with mental health conditions and disabilities.
