Serious injury to individuals in custody as a result of violent individuals in custody-on-individuals in custody incidents (monthly rate per 1,000 ADP)
Provide a safe and secure environment for individuals in custody, staff and host communities. — Ensure the security and safety of individuals in DOC custody.
DOC's own reporting says the FY22-to-FY24 decline in serious injuries to incarcerated people from violence was the result of a multi-pronged effort to better manage the jails, including more searches for contraband weapons. The subsequent FY25 increase coincided with a nearly 10 percent jump in the average daily jail population, a rise in the share of people held on serious violent charges following bail reform, continued uniformed staff attrition, and a state prison workers' wildcat strike that temporarily halted transfers of sentenced individuals out of city custody, all of which DOC cited as contributing factors.

Why this is tracked
The 2015 Nunez consent decree grew out of a lawsuit brought by a teenager who alleged he was beaten by a DOC captain on Rikers Island; it mandated reforms including de-escalation policies and restrictions on tactics like head strikes. A court-appointed monitor has since filed dozens of reports finding the City out of compliance with the order, and in 2025 a federal judge appointed an outside Remediation Manager to take over reform efforts after the City was held in contempt of multiple provisions. That history is why "safe and secure" custody in NYC's jail system is not just a routine institutional goal but a specific, court-monitored legal obligation.
