Detailed Insights

New Bilibid Prison (NBP) was originally designed for 6,345 inmates but has ballooned to more than 29,000 prisoners as of late 2022, earning global attention for its extreme overcrowding. Silivri Prison’s modern infrastructure, completed in 2008, positions it as Turkey’s flagship correctional facility, while serving as Europe’s largest correctional complex. Klong Prem Central Prison, located in Bangkok’s Chatuchak District, houses different populations – male, female, and drug‑offender units – with a combined capacity of around 20,000 inmates, including a female death‑row population. Los Angeles County Jail is the United States’ largest jail system, sheltering close to 20,000 inmates and enduring chronic challenges such as gang conflicts and violence. Tihar Jail, spanning 400 acres in Delhi, contains nine central prisons and offers rehabilitation programs to its extensive inmate cohort.
