"On Dec. 31, 2016, the most recent date for which data is available, there were roughly 2.2 million people incarcerated in prisons and jails throughout the U.S. Add that to the 4.5 million people being supervised in the community by a parole or probation agency, and 1 in 38 adults under some form of correctional supervision. Community corrections has turned into an add-on, rather than a relief valve, to the mass incarceration dilemma in the U.S."
