The Marshall Project conducted a three-month survey of state corrections departments, finding more than 61,250 technical parole violators in 42 state prison systems as of early 2017. These are the inmates who are currently locked up for breaking a rule of parole, rather than parolees who have been convicted of a new crime; the number does not include those in county and local jails, where thousands more are likely held. (The eight remaining states — Alabama, Connecticut, Louisiana, North Carolina, Oklahoma, South Carolina, Tennessee, and Virginia — said either they did not keep current state-level data or it would be too costly to generate.)
The total, 61,250, seems small, given the 2.3 million people behind bars in this country. Imprisoning fewer technical violators would make only a dent in the effort to reduce mass incarceration. “But still,” said Marc Mauer, executive director of The Sentencing Project, “the numbers aren’t trivial.”
To Mauer and other experts on what drives prison and jail populations, the fact that tens of thousands of people are incarcerated for infractions such as traveling without permission or frequenting a bar that serves alcohol is significant in itself.
That may be all the more true in seven states — Arkansas, Georgia, Illinois, Kentucky, Missouri, New York, and Pennsylvania — which, according to the Marshall Project data, have more technical parole violators in their prisons than the other 35 states combined
