Reports & evaluations
Editorial summaries of major prison-reform reports — global trends from PRI and the UN, US mass-incarceration analysis from PPI and Vera, country-specific inspections from oversight bodies. Each entry links to the primary source.
Penal Reform International · global
PRI's flagship annual report on the state of the world's prisons. Documents continued global prison-population growth (~11.5 million worldwide), severe overcrowding affecting more than 60% of national systems, and the criminalisation of poverty as a major driver. Spotlights the disproportionate incarceration of women, the persistence of pre-trial detention without trial, and the rise of mass life-without-parole sentences as an alternative to the death penalty in retentionist states.

PPI's annual single-snapshot analysis of the US carceral system: 1.9 million people behind bars across federal prisons, state prisons, local jails, immigration detention, juvenile facilities, and military / territorial prisons. Counters the common claim that 'most prisoners are non-violent drug offenders' by breaking down offense categories, and exposes the churn of pre-trial detention in local jails.

Amnesty's annual census of recorded executions and death sentences worldwide. 2024 was the deadliest year on record in decades, driven primarily by Iran, Iraq, and Saudi Arabia, with drug-related offences accounting for a large share. China remains the world's biggest executioner but figures remain a state secret.
death penalty abolitiondrug policyHarm Reduction International · global
Biennial assessment of harm-reduction coverage worldwide. Documents the criminalisation of drug use as a major driver of prison overcrowding and disease transmission, with HIV / hepatitis-C prevalence in many prisons running 5-10x community rates.

An interactive county-level dataset of US jail and prison incarceration from 1970 to present. Reveals that the post-2000 growth in incarceration has shifted from large urban centres to small and rural counties, and that pre-trial jail populations remain the fastest-growing segment.

CPT's seven-prison inspection of France documents severe overcrowding (some facilities at 200%+ of capacity), inadequate access to outdoor exercise, and serious shortcomings in mental-health care. France's prison occupancy hit a record 78,082 detainees in 2024 against a capacity of ~60,400.

Official UK MoJ projections show the England & Wales prison population continuing to rise past 100,000 by 2027 unless legislative action is taken. The 2024 emergency early-release scheme (SDS40) is treated as a temporary mitigation, not a structural fix.

Argues that 'tough-on-crime' policies have produced record incarceration levels with no measurable safety gains. Documents the consequences for women, children of imprisoned parents, and people with mental health needs.

Examines why suicide remains the leading cause of death in English and Welsh prisons. Analyses the link between short sentences, remand churn, and self-inflicted deaths, and proposes reforms including expanded mental-health screening and the abolition of short prison sentences.

ICPR's quinquennial census of women in prison worldwide. Documents ~740,000 women held globally, with the largest absolute numbers in China, the United States, and Russia. Notes the rising rate of women's incarceration in El Salvador, Türkiye, and several Central Asian states.
women prisonersglobal trendsThe Sentencing Project · United States
Documents the explosion of US life-without-parole (LWOP) sentences since the 1980s. More than 56,000 people are serving LWOP, with the elderly and infirm population growing rapidly while posing minimal public safety risk. Argues that 'compassionate release' and parole-eligibility reforms could safely return thousands.

Documents how pre-trial detention — meant under EU and international law to be a measure of last resort — has become routine in many member states. Identifies bias against foreign nationals and people of colour, and weak judicial scrutiny of detention requests.

Still the most-cited UN technical guide on cutting prison populations. Covers pre-trial detention alternatives, diversion programmes, sentencing reform, and early release — with case studies from Brazil, Kenya, South Africa, and the United Kingdom.
