Jail population on Long Island
Long Island's three correctional facilities housed an average 2,394 inmates a day in 2016, the latest year for which averages are available and the sixth consecutive year in which the number declined. Nassau was down 37.2% from its 1998 peak, and Suffolk was down 24.3% from its 2010 peak. The table below gives a breakdown of the inmates.
"State Readies" are those sentenced by the court to a state prison term who have not been transported to the NYS Department of Corrections and Community Supervision. "Other Unsentenced" are those awaiting either arraignment, trial or sentencing by the court, or who are parole violators with new arrests. This information was made available by the New York State Division of Criminal Justice Services. This database was posted on Dec. 22, 2017.
