"The World Prison Brief is an online database providing free access to information on prisons and the use of imprisonment around the world. It is a unique resource, offering a foundation for evidence-based development of prison policy and practice globally. [...] In addition to providing access to the World Prison Brief database, this website holds other publications by ICPR and its original host, the International Centre for Prison Studies (which was formed in 1997 and merged with ICPR in 2014). These include the World Prison Population List (and complementary lists on Female Imprisonment and Pretrial/Remand Imprisonment), the handbook on A Human Rights Approach to Prison Management, and bimonthly editions of the International Prison News Digest. See the 'Research and publications' page."
