People in prison
Social characteristics of adult prisoners
Before they ever come into contact with the prison system, most prisoners have a history of social exclusion, including high levels of family, educational and health disadvantage, and poor prospects in the labour market.
The failure of mainstream agencies to deal with these aspects of social exclusion means that the Prison Service and Probation Service are in many cases being asked to put right a lifetime of service failure.

People from an ethnic minority background in prison
Over a quarter (27%) of the prison population, 24,041 people, are from an ethnic minority group. 12% identify as Black/Black British; 8% as Asian/Asian British; and 5% as from a mixed ethnic background.1Ministry of Justice (2025). Table 1.Q.7, Prison population: 30 September 2025. Offender management statistics quarterly: April to June 2025.
If our prison population reflected the ethnic make-up of England and Wales, we would have around 9,000 fewer men and boys in prison2Kneen, H. (2017).

Ethnicity in prisons in England and Wales
The number of Asian and mixed ethnicity prisoners has risen sharply since 2004
Source: Ministry of Justice (2025). Offender management statistics quarterly: April to June 2025.
A 2016 study found that people from ethnic minority backgrounds face disproportionately higher odds of receiving custodial sentences for indictable offences at the Crown Court, with Black people 53%, Asian people 55%, and other ethnic minority groups 81% more likely to be imprisoned compared with white people, even after accounting for higher not guilty plea rates.4Hopkins, K., Uhrig, N. and Colahan, M. (2016). Associations between ethnic background and being sentenced to prison in the Crown Court in England and Wales in 2015. Ministry of Justice.
Despite this evidence, in 2025 the government introduced legislation to block Sentencing Council guidelines directing sentencers to request pre-sentence reports (PSRs) for people from minority ethnic and cultural backgrounds.5Ministry of Justice (2025, 1 April). Government to introduce legislation to block new sentencing guidelines. PSRs are widely understood to enhance judicial understanding of defendants’ circumstances, what would be the most effective sentences, and social backgrounds unfamiliar to the judge.6The Lammy Review (2017). An independent review into the treatment of, and outcomes for, Black, Asian and minority ethnic individuals in the criminal justice system.
Defendants from an ethnic minority background are more likely to be remanded in custody than white defendants. In 2024, Black defendants were 29% more likely, defendants of mixed ethnicities 22% more likely, and Asian defendants 19% more likely to receive this outcome.7Ministry of Justice (2025). Ethnicity and the criminal justice system 2024.
People from ethnic minority backgrounds serve a greater proportion of their determinate sentence in prison than people from a white background. In 2024, Black people spent the highest proportion of their sentence in prison (62%), followed by those from a mixed ethnic background (58%), white (56%), other ethnic background (54%), and Asian (53%) prisoners.8Ministry of Justice (2025). Table 6.02, Chapter 6: Offender management tables. Ethnicity and the criminal justice system 2024
3% of surveyed men, 1% of women and 8% of children in custody said that they identify as Gypsy, Roma or Traveller (GRT),9HM Chief Inspector of Prisons (2025).

Fewer Black, Asian and minority ethnic men in prison say they have a member of staff they could turn to for help, or are treated with respect by staff. More say they have been bullied or victimised by staff.11HM Chief Inspector of Prisons (2025). Table 6, Men’s comparator workbooks, Annual report 2024–25. HM Stationery Office.
A 2022 inspectorate review found that many Black prisoners felt that uneasy relationships with staff partly stemmed from underlying prejudice and racism, while few staff acknowledged the possibility of racism in their establishments.12HM Chief Inspector of Prisons (2022). The experiences of adult black male prisoners and black prison staff. HM Stationery Office. People in prison from an ethnic minority background are more likely to report being recently restrained or segregated.13HM Chief Inspector of Prisons (2025). Table 6, Women’s and men’s comparator workbooks, Annual report 2024–25. HM Stationery Office.
Prison officers remain less ethnically diverse than prisoners. In March 2025, 10% of public sector prison officers (bands 3–5) identified as Black, 3% as Asian, and 83% as white, whereas 12% of prisoners identify as Black, 8% as Asian, and 72% as white. But 13% of officers did not have their ethnicity recorded or did not disclose it, compared with only 1% of prisoners.14Ministry of Justice (2024). Table 1.Q.7, Prison population: 30 September 2025.

Older people in prison
With prison sentences getting longer, people are growing old behind bars. The number of people in prison aged 60 and over has grown rapidly over the last two decades. There are more than four times the number there were in 2002.15Ministry of Justice (2025). Table 1.A.18, Prison population: 2025. Offender management statistics quarterly: January to March 2025.
Almost one in five (18%) of the prison population are aged 50 or over—16,163 people. Of these 4,559 are in their 60s and a further 2,109 people are 70 or older.16Ministry of Justice (2025). Table 1.Q.6, Prison population: 30 September 2025. Offender management statistics quarterly: April to June 2025.
The government projects a 14% rise in the prison population by 2029, including a significant increase in older prisoners. Those aged 50 and over are expected to grow by 15% and those aged 70 and over by 23%.17Ministry of Justice (2025). Table 4.1, Prison population projections: 2025 to 2030: Statistical tables.

People with neurodivergent conditions
Neurodiversity
There is no universally accepted definition of neurodiversity. It was originally introduced as an alternative to deficit-based language to describe conditions that influence how people process information. People with neurodiverse conditions may have a different pattern of cognitive strengths, difficulties and perspectives to ‘neurotypical’ individuals. The Ministry of Justice considers neurodivergent conditions to include (but not exclusively) learning disabilities, learning difficulties, attention deficit hyperactivity disorder (ADHD), autism and acquired brain injury.19Ministry of Justice (2023). Updated action plan. A response to the Criminal Justice Joint Inspection: Neurodiversity in the criminal justice system.
People with neurodivergent conditions face systemic barriers in the criminal justice system, including limited understanding of their needs, inadequate support, and the inconsistent implementation of reasonable adjustments. In prison, they are often excluded from key aspects of the regime, including rehabilitative opportunities.20Criminal Justice Joint Inspection (2021). Neurodiversity in the criminal justice system: A review of evidence.
The lack of routine screening makes it difficult to estimate how many people in prison have a neurodivergent condition. Following a review of evidence, inspectors suggested that “perhaps half of those entering prison could reasonably be expected to have some form of neurodivergent condition”, compared to professionals’ estimate of 15–20% of the general population.21Criminal Justice Joint Inspection (2021). Neurodiversity in the criminal justice system: A review of evidence.
Of prisoners screened through educational assessments in England in 2024—25, over half (57%) were identified as having a learning difficulty or disability.22Ministry of Justice (2025). Table 1.4, Prison education tables 2024–25. Prison education and accredited programme statistics 2024 to 2025.
In 2022–23, basic screening upon entry to custody suggested that nearly a third of arriving prisoners (31%) had a neurodivergent need.23House of Lords written question HL5704, 6 March 2023. But this data is not routinely published.
Inspectors surveying prison and probation staff found consistent low levels of awareness, understanding and confidence relating to neurodiversity. Less than a quarter (24%) of prison staff who responded said that they had received any training about neurodiversity.24Criminal Justice Joint Inspection (2021). Neurodiversity in the criminal justice system: A review of evidence. Three out of four criminal justice professionals in England and Wales believe that impairments are sometimes missed.25Equality and Human Rights Commission (2020). Inclusive justice: a system designed for all.
Over the past decade the government has invested in liaison and diversion services in police custody suites and the criminal courts. These aim to identify people who have vulnerabilities, including neurodivergent conditions, and divert them towards a setting more appropriate for treatment. The roll-out achieved 100% coverage across England in March 2020,26NHS England website and the services appear to increase diversion from custodial sentences.27Disley, E. et al. (2021). Findings from the national evaluation of Liaison and Diversion services in England. RAND.
Foreign nationals in prison
Who are foreign national prisoners?
The term “foreign national prisoner” encompasses many different people who have committed a criminal offence. People may have come to the UK as children; they may be second generation immigrants — often from former colonies; asylum seekers; people who have been given indefinite leave to remain as refugees; European and European Economic Area nationals; people who have been trafficked into the country; visitors or workers.
Foreign nationals (non-UK passport holders) currently make up one in eight people in prison in England and Wales (12%). On 30 September 2025 there were 10,737 foreign nationals in prison.28Ministry of Justice (2025). Table 1.Q.9, Prison population 30 September 2025. Offender management statistics quarterly: April to June 2025.
Foreign national prisoners come from 175 countries—but over half are from 11 countries (Albania, Poland, Ireland, Romania, India, Jamaica, Lithuania, Pakistan, Iraq, Iran, and Portugal).29Ministry of Justice (2025). Table 1.Q.12, Prison population 30 September 2025. Offender management statistics quarterly: April to June 2025.
Between 2002 and 2008, the number of foreign nationals in prison increased by nearly 50%, compared with a 13% rise among British nationals. However, numbers steadily declined over the following decade, though have slightly risen over the past four years. Today, there are 6% fewer foreign nationals in prison than at their 2008 peak, while the number of British nationals has increased by 8%.30Ministry of Justice (2025). Table 1.A.20, Prison population: 2025. Offender management statistics quarterly: January to March 2025.
Almost one in 10 women in prison (9%) are foreign nationals.31Ministry of Justice (2025). Table 1.Q.11, Prison population 30 September 2025. Offender management statistics quarterly: April to June 2025. A research study found that in a sample of migrant women in prison, over half (56%) had been coerced or trafficked into offending.32Hales, L. and Gelsthorpe, L. (2013). The criminalisation of migrant women: Research findings and policy and practice implications. Prison Service Journal, 206, 25-30.
A lower proportion of foreign nationals are in prison for violent (30%) and sexual offences (16%), compared with the overall prison population—36% and 19% respectively. However, they are more likely to be in prison for a drug offence (20%) or miscellaneous crimes against society (9%), compared with 13% and 5% for the overall prison population.33Ministry of Justice (2025). Table 1.A.26, Prison population: 2025. Offender management statistics quarterly: January to March 2025.
5,343 people were either removed or voluntarily returned to their home country in the year to September 2025 following a conviction for a criminal offence—a 10% increase compared with the previous year.34Home Office (2025). Table Ret_D03, Returns detailed datasets, year ending September 2025. Immigration system statistics, year ending September 2025.
Women in prison
Why focus on women in prison?
A series of inquiries and reports in recent decades have all concluded that prison is rarely a necessary, appropriate or proportionate response to women who offend, including the influential Corston Report on women with particular vulnerabilities in the criminal justice system — published almost 20 years ago.35Baroness Corston (2007). The Corston report. Home Office.
In June 2018, the Ministry of Justice published its long-awaited Female Offender Strategy. It promised a focus on early intervention, community-based solutions and better custody for those women who do have to be in prison. It recognised the evidence base for a distinct approach to women and a local whole system approach.36Ministry of Justice (2018). Female offender strategy.
In 2023 the Ministry of Justice launched a new delivery plan, backed by a promised £24m investment in community solutions across 2023–25.37Ministry of Justice (2023). Female offender strategy delivery plan 2022–25. CP 772. £15m had been awarded by October 2023.38House of Commons written question 203057, 25 October 2023.
In September 2024, the Labour government announced the creation of a Women’s Justice Board, aimed at developing earlier interventions for women and enhancing alternatives to prison, such as community sentences and residential women’s centres. A strategy was expected to be published in Spring 2025,39Ministry of Justice (2024, 24 September). Extra support for women through the criminal justice system announced. however, this appears to have been delayed.40Ministry of Justice (2025). Women’s Justice Board minutes: held on 22 July 2025.
On 30 September 2025 there were 3,527 women in prison in England and Wales — accounting for just 4% of the total prison population.41Ministry of Justice (2025). Table 1.Q.1, Prison population 30 September 2025. Offender management statistics quarterly: April to June 2025.
Women entered prison on 6,275 occasions in the year to June 2025 — either on remand or to serve a sentence.42Ministry of Justice (2025). Table 2.Q.1, Prison receptions: April to June 2025. Offender management statistics quarterly: April to June 2025.
Most women entering prison to serve a sentence (63%) have committed a non-violent offence. In 2024, more women were sent to prison to serve a sentence for theft than for criminal damage and arson, drug offences, possession of weapons, robbery, and sexual offences combined.43Ministry of Justice (2025). Table 2.A.12, Receptions 2024. Offender management statistics quarterly: October to December 2024.

46% of women leaving prison are reconvicted within one year. Of those who reoffended, 64% were serving a sentence of 12 months or less.50House of Lords written question HL13460, 19 January 2026.
Women released from prison are more likely to reoffend, and reoffend sooner, than those serving community sentences.51Hedderman, C. and Jolliffe, D. (2015).

Children in prison
Where are children held?
There are currently four main types of accommodation used to detain children in England and Wales.
Secure children’s homes (SCHs) — The eight SCHs generally accommodate younger children and are intended to provide tailored support for their needs.
Secure Training Centre (STC) — The sole remaining STC is a purpose-built place of detention for more vulnerable children aged 12–17, intended to provide education and rehabilitation.
Secure schools — There is currently one secure school, operated by Oasis Restore, which opened in June 2024 and will eventually accommodate up to 49 children. but has been temporarily closed since September 2025 due to safety concerns about heavily damaged doors.59Youth Justice Board (2024, 4 October). Inside the Oasis Restore secure school.
Young Offender Institutions (YOIs) — The five four YOIs in England and Wales are designated as prisons that can accommodate children — although due to the current prison capacity crisis for adults, there are currently 118has seen young adults also accommodated there.60Youth Justice Board (2026). Table 1.4, Youth custody population November 2025. Youth custody data.
Children are committing fewer recorded crimes — proven offences in 2024 were 61% lower than in 2014.61Youth Justice Board (2025). Table 4.1, Chapter 4—Proven offences by children. Youth justice statistics: 2023 to 2024.
The number of children sentenced to in custody fell steeply from 4,657 in 2009–10 to 660 children in 2023–24, although this number was an increase of 21% on the year before (546 children).62Youth Justice Board (2025). Table 5.4, Chapter 5—Sentencing of children. Youth justice statistics: 2023 to 2024. And previous editions.

Table 1, Children’s workbook, Children in custody 2024–25.
In 2024–25, inspectors were concerned that children’s perceptions of their time in custody had worsened, with too much time still spent locked up, higher levels of violence than the adult prison estate, and poor relationships with staff.72HM Inspectorate of Prisons (2025). Children in custody 2024–25.

Separation of children from their peers continues to be widespread. There were 1,038 instances of separation involving 480 children in 2023–24. Nearly two-thirds of surveyed children (64%) had been kept locked up and prevented from mixing as a punishment. Inspectors found separation is a common method of managing conflict and risk, and that many children choose to self-separate for safety.75HM Chief Inspector of Prisons (2024).

Young adults in prison
What is a young adult?
The definition of “young adults” is not straightforward in criminal justice. The DYOI sentence (a custodial sentence specifically for young adults) legally classifies them as aged 18–20, however HM Prison and Probation Service (HMPPS) policy and practice increasingly recognises that brain development and maturation takes place up to the age of 25. Yet currently, most data sources report on young adults aged 18–24. Data in this section refers to 18–24-year-olds, unless otherwise stated.
10,813 young adults are currently in prison in England and Wales—they account for 12% of the total prison population.80Ministry of Justice (2025). Table 1.Q.6, Prison population: 30 September 2025. Offender management statistics quarterly: April to June 2025.
There are now almost half as many young adults in prison as there were 20 years ago.81Ministry of Justice (2025). Table 1.A.18, Annual prison population: 2025. Offender management statistics quarterly. January to March 2025. And previous editions.
A 2015 study found that 18–24 year olds have the highest level of Black, Asian and ethnic minority over-representation in the adult prison estate of all age groups. If our prison population reflected the make-up of England and Wales, we would have 2,850 fewer Black, Asian and ethnic minority young adults in prison.82Kneen, H. (2017). Table 11, An exploratory estimate of the economic cost of Black, Asian and minority ethnic net overrepresentation in the criminal justice system in 2015. Ministry of Justice.
