Sweden youth detention increased in 2025 as the Swedish Prison and Probation Service (Kriminalvården) continued to operate under severe pressure, with overcrowding in both remand prisons and prisons and a growing number of children and young people entering the correctional system.
According to annual statistics published by the authority, the average occupancy rate in permanent places reached 122 percent in remand prisons and 141 percent in prisons last year. The pressure was mainly linked to a higher inflow of clients and longer sentences, two trends that have reshaped Sweden’s correctional system in recent years.
More teenagers entered Swedish remand prisons
The most politically sensitive figure concerns children aged 15 to 17. In 2025, 558 remand detentions involving 15–17-year-olds were ended, a 17 percent increase compared with 2024.
The authority also reported that almost 2,000 enforcement proceedings were initiated for people under 21, around 70 more than the previous year. For young people under 21 who began serving prison sentences, the average sentence length rose to almost 990 days, around 100 days longer than in 2024.
Susanne Wedin, department director at the Swedish Prison and Probation Service, said the trend places significant demands on the authority’s work. “The fact that more and more children and young people are being taken into our detention centres and prisons places great demands on our operations,” she said, adding that the system must continue adapting to the specific needs of this group.
The figures underline a broader shift in Swedish criminal justice. Sweden has traditionally combined strict legal safeguards with a welfare-oriented approach to young offenders, but the rise in gang-related shootings and bombings has pushed youth crime to the centre of national politics.
Overcrowding adds pressure to youth justice reforms
The increase in young detainees comes while the correctional system is already struggling with capacity. Kriminalvården described the average occupancy rate as historically high, warning that it is putting pressure on the authority’s resources and operations.
Sweden has been planning a major expansion of prisons and remand facilities. In earlier capacity assessments, the authority said it may need to increase the number of places significantly over the next decade, partly because of tougher criminal justice policies and longer sentences.
This capacity issue is directly linked to the government’s youth justice agenda. Sweden is preparing to introduce special youth prisons for convicted 15–17-year-olds, a reform intended to replace parts of the current system of youth homes for serious offenders. The first such facilities are expected to be introduced from July 2026.
At the same time, the government has recently changed course on one of its most controversial proposals. It had considered lowering the age of criminal responsibility from 15 to 13 for serious offences, but the plan was withdrawn after it became clear that there was not enough parliamentary support. The government now intends to propose lowering the age to 14 instead.
Sweden’s debate is moving between punishment and prevention
The new statistics are likely to intensify Sweden’s debate over how to respond to youth crime. Supporters of tougher measures argue that criminal networks increasingly recruit minors because they face lighter penalties and can be used to carry out serious offences. For them, lowering the age of criminal responsibility and creating youth prisons are necessary responses to a changing pattern of violence.
Critics, including child rights experts and parts of the opposition, warn that expanding detention for children risks weakening rehabilitation and may expose vulnerable young people to more harmful environments. They argue that Sweden should focus more strongly on prevention, social services, schools and early intervention in disadvantaged areas.
This tension is not unique to Sweden, but it has become especially visible there because of the scale of gang-related violence and the country’s historically strong emphasis on welfare-based criminal justice. The question is no longer only how Sweden punishes young offenders, but whether its institutions can combine public safety with child protection and rehabilitation.
Women also entered the system in higher numbers
The 2025 statistics also show an increase in the number of women entering the correctional system. The number of initiated enforcement proceedings involving women rose by seven percent to nearly 3,350 cases.
Women still account for a relatively small share of the prison population, but the increase adds another layer to the capacity challenge. According to the Swedish Prison and Probation Service, women represented 10 percent of the inflow to prison and 18 percent of the inflow to probation during the year.
The overall rate of reoffending within three years remained at 31 percent, broadly in line with recent years. That figure will remain central to the debate over whether Sweden’s tougher criminal justice strategy can reduce crime in the long term, especially among younger offenders.
