As of the most recently available public data, Rikers Island typically holds around 6,000–7,000 people on a given day , not the 20,000-plus it held at its peak in the 1990s.

NYC’s own figures showed about 6,182 people in custody on Rikers Island facilities as of August 1, 2023 , and reports in 2025 describe the “today” population as “closer to 6,000–7,000.” That means that if you’re asking “how many inmates in Rikers Island” right now, the best realistic estimate is in that mid‑thousands range, with day‑to‑day fluctuations.

City policy aims to shrink the total jail population to about 3,300 people citywide as part of the plan to close Rikers and replace it with smaller borough-based jails, though that target has been pushed and debated over time.

In short: historical peak over 20,000; today, roughly six to seven thousand people held there on a typical day.

Trend and context

  • Rikers is no longer at its historic highs but still holds thousands of mostly pretrial detainees on any given day.
  • Official planning documents project a much smaller future jail system (around 3,300–3,900 daily capacity) once Rikers is eventually closed and people are moved into new facilities.
  • Oversight reports note that the population has risen somewhat since 2021 , even as reform advocates push for reductions.

TL;DR: Rikers Island currently holds on the order of six to seven thousand people , with city plans aiming to reduce the overall jail population significantly in coming years.
