From Challenges to Solutions: Mapping European Strategies on Prison Overcrowding
EuroPris has published a new report titled From Challenges to Solutions: Mapping European Strategies on Prison Overcrowding. The report provides an overview of how prison administrations across Europe are addressing prison overcrowding and their responses to it.
The mapping exercise was conducted between April and September 2025. It is based on structured survey responses from 33 national and regional prison administrations, representing approximately 80% of EuroPris members. The findings are complemented by expert interviews and institutional input.
The report reflects the contributions of prison administrations, representatives, and experts who shared their experience and perspectives.
Key findings
- Prison overcrowding remains a widespread and systemic challenge with implications for safety, dignity, and compliance with international standards.
- Between 2020 and 2025, 24 of the 33 participating administrations reported an increase in prison populations. Notable increases were identified in France, Sweden, Ireland, Northern Ireland, and Croatia.
- Overcrowding affects more than occupancy levels. It has consequences for access to healthcare, education, mental health support, staffing capacity, and overall safety.
- Measures taken by prison administrations operate at different levels. These include immediate operational responses, medium-term systemic measures, and long-term strategic approaches such as population forecasting and infrastructure planning.
- No single measure is sufficient on its own. Sustainable progress depends on coordinated action across the justice system and investment in staff, activity spaces, and reintegration pathways.
Purpose of the mapping
The report offers an overview of how prison overcrowding is understood and managed within the responsibilities of European prison administrations. It is intended to support informed dialogue among policymakers, practitioners, and partners, and to encourage shared learning and forward planning for more humane and resilient prison systems.

The EU’s competitiveness will increasingly depend on the digitalisation of all sectors, which will drive investment. Digitalisation and the deployment of artificial intelligence (AI) will be essential to the ability of public authorities to deliver high-quality public services, notably also in the field of justice. Europe’s Digital Decade is underway with the ambition that by 2030 the EU has all key public services available online. The ultimate aim will be to increase the efficiency of public services by making them digital by default, stimulating productivity.
