The Caribbean nation has the most overcrowded prisons of any country worldwide and its institutions are operating at 454 percent capacity. That has resulted in 80 to 100 men being crammed into a single cell at once, malnutrition and the spread of disease. Many of Haiti's inmates have not been convicted of a crime and the UN has condemned the situtation, saying inmates are subject to daily violations of their human rights.
The situation in the Philippines is similar and conditions in its prisons have deteriorated steadily since President Rodrigo Duterte launched his war on drugs. That has seen the number of arrests skyrocket with thousands of people thrown into prison. That has seen occupancy rates stretched to 436 percent of capacity and Quezon City Jail is a good example. An ABC News report claims the facility was built to house 262 prisoners and it now hosts over 3,000.
El Salvador comes third for prison overcrowding with its institutions operating at 348.2 percent of their capacity.
