French prison population reaches 90,020 inmates as overcrowding rises to 142%

Capacity shortages and floor mattresses

Official statistics from the French Ministry of Justice published on 2 October 2026 showed that the inmate population in France reached 90,020 on 1 September 2026. The figure represents an annual rise of 6.8% compared to the 84,311 detainees recorded on 1 September 2025, adding more than 5,700 inmates across the national penal system in twelve months. Over the same period, operational prison capacity expanded by only 1.2%, increasing by 734 spots to a total of 63,348 places. The growing gap between inmate numbers and available cells pushed the nationwide prison occupancy rate to 142.1%. A total of 8,347 detainees were forced to sleep on floor mattresses on 1 September due to bed shortages, marking a 51.8% rise from the 5,500 people sleeping on floors a year earlier.

Remand center crisis and regional variations

The overcrowding crisis is concentrated in remand prisons (maisons d'arrêt), which house individuals serving short sentences alongside pre-trial detainees awaiting trial. These remand facilities recorded an average occupancy density of 176.1% on 1 September, while holding 24,536 pre-trial detainees who remain legally presumed innocent. A total of 32 detention facilities or specialized wings registered occupancy levels exceeding 200%. Regional disparities further accentuate the strain on detention centers across French territory. The Paris administrative region registered an occupancy density of 163.5%, the Toulouse region stood at 159.3%, and French overseas territories recorded 150.2%.

European warnings and legal rulings

Detention conditions in French prisons have drawn repeated scrutiny from international legal and human rights authorities. In early 2026, the Council of Europe issued a report detailing widespread overcrowding, unsanitary physical environments, and elevated levels of violence, warning that French penal institutions risk devolving into human warehouses. The European Court of Human Rights has sanctioned France multiple times over degrading detention conditions, most recently issuing a condemnation in January 2026. Data published by the Council of Europe for 2025 placed France on par with Turkey at 131 inmates per 100 available places. That ratio placed France ahead of Croatia with 123 inmates per 100 places and Italy with 121.

Infrastructure plans and systemic criticism

In response to capacity deficits, the Ministry of Justice plans to deploy 3,000 additional places in modular facilities, which offer lower construction costs and faster assembly times, with 1,500 of those units scheduled for 2027. The measure comes as progress lags on an earlier national plan launched in 2018, which aimed to build 15,000 prison places but has delivered less than one-third of that target. In an opinion published in the Journal officiel in early July, Dominique Simonnot, the Contrôleure générale des lieux de privation de liberté, criticized the absence of broad national measures over nearly three years to halt escalating prison numbers. Simonnot stated that sentence adjustments and alternatives to incarceration remain underused, arguing that continuous facility construction cannot solve prison overcrowding.

The construction of new facilities cannot constitute a relevant response: given the current pace of overcrowding growth, it would be necessary, in order to absorb it, to open a penitentiary every six weeks.
