World Prison Brief · 201 jurisdictions · % of official capacity
Prison occupancy rate, as a percentage of official capacity — a ratio, not addable. A diverging palette centred on 100% (= nominal capacity): green for under-occupation, red for critical overcrowding, a natural threshold that doesn't exist on the other prison indicators.
World Prison Brief, 201 jurisdictions covered (data missing for 15).
A value above 100% means the prison population exceeds the facility's official capacity.
The Republic of the Congo (617% of official capacity) and Cambodia (409%) illustrate extreme prison overcrowding, with facilities holding four to six times more inmates than they were designed for — a situation documented by human rights organisations as an aggravating factor for mistreatment.
