Following a statewide corrections officer strike in February 2025 and the termination of over 2,000 officers, New York State prisons have been unable to accept timely transfers of people sentenced to state time. This brief analyzes the resulting surge in the “state-ready” population on Rikers Island—those awaiting transfer to prison—which rose more than eight-fold from 101 to 875 people from February to June 2025. As of the end of June 2025, these individuals accounted for 11% of the total jail population and are responsible for 89% of February-to-June 2025 jail population growth. In short, the jail population would have changed little in the first half of 2025 if not for the ripple effects of the corrections officer strike.

This research brief summarizes what we know about New York City’s jail population since the COVID-19 outbreak. The data point to a 30 percent reduction in the city’s daily jail population from March 18 to April 29—attributable to urgent efforts to gain people’s release as well as to declining arrests, as people sheltered indoors at the start of the pandemic. Since then, the use of jail re-increased, reversing over half of the prior reductions. If the current trend continues, the jail population will return to its pre-COVID-19 level by mid-February 2021. The COVID-19 era has also seen considerable variations in the jail trends applicable to different subgroups, with the numbers held in pretrial detention progressively rising, even as incarceration has remained low among people convicted and serving sentences of one year or less. After reviewing key emergency release strategies adopted at the outset of the pandemic, this research brief documents overall jail trends and more specific changes in the composition of the jail population from mid-March to the beginning of November 2020.
