One out of every three people who were behind bars last night were confined in a jail; two out of every three correctional facilities is a jail, and almost every person (95%) released from a correctional facility today was released from a jail.

Jails are literally mass incarceration's front door, yet the scant attention paid to jails and jail policy is itself a key impediment to reform.

The Prison Policy Initiative seeks to put jails and the need for jail reform directly into the national discussion on criminal justice reform.

Below is some of our key research about jail and jail policies:

Our report and comprehensive graphic provide the big picture: 2.3 million people are locked up in more than 6,000 correctional facilities operated by thousands of agencies.

  • Who is in jail? Deep dive by Peter Wagner, December 8, 2015.
    Jail churn and pre-trial detention are even more important than a quick look at the data suggests. Here, we correct for the fact that a sizable number of people are housed in jails for other agencies.
