Overview
- The Chancellerie reported May 1, 2026, that French prisons held 88,654 detainees, a year-on-year rise of about 5,000 and a new official high.
- Overall occupancy stands at 140% with maisons d'arrêt at 172.6%, 7,693 mattresses were placed on cell floors and 33 facilities house two inmates per single place at 200% occupancy or more.
- Prison capacity has barely kept pace with demand with roughly 750 places added in the past year and fewer than one-third of the 15,000 places pledged in the 2018 expansion plan delivered to date.
- The Justice Ministry plans 3,000 extra modular places with half expected by 2027 while political debate continues over regulatory measures to curb incarceration and Interior Minister Gérald Darmanin has opposed automatic release rules.
- Staff and directors have staged strikes and warned of safety problems, the Council of Europe has flagged human-rights risks, and the overcrowding could increase violence, illness and legal challenges for detainees and workers.
