The United Kingdom has three distinct legal systems with a separate prison system in each: one for both England and Wales, one for Scotland, and one for Northern Ireland. As of June 2023, the United Kingdom has the highest per-capita incarceration rate in Western Europe, at 159 people per 100,000 in England and Wales; 162 people per 100,000 in Scotland; 97 people per 100,000 in Northern Ireland; and the largest prison population in Western Europe.{{cite web |last1=Sturge |first1=Georgina |title=UK Prison Population Statistics |url=https://researchbriefings.files.parliament.uk/documents/SN04334/SN04334.pdf |publisher=House of Commons Library |access-date=17 October 2023}}[http://www.prisonstudies.org/highest-to-lowest Highest to Lowest].

Demographics

{{also|Race and crime in the United Kingdom}}

People of minority ethnicities (BAME) constitute 13% of the general population, but make up 27% of the prison population. In 2017, a review led by David Lammy MP concluded that the justice system was biased against this group, and required reform.{{Cite web|url=https://www.bbc.co.uk/news/uk-41191311|title=Bias against ethnic minorities 'needs to be tackled' in justice system|date=8 September 2017|website=BBC News|access-date=31 March 2019}} In 2019, Lammy expressed deep concern at the high proportion of BAME males in young offender institutions with 51% of boys in young offender institutions identifying as BAME, saying that "England and Wales are now hitting an American scale of disproportionality in our youth justice system".{{Cite web|url=https://www.theguardian.com/society/2019/jan/29/more-than-half-young-people-jail-are-of-bme-background|title=More than half of young people in jail are of BME background|last=Grierson|first=Jamie|date=29 January 2019|website=The Guardian|access-date=31 March 2019}} The over-representation of the black population in prisons may be a result of stop and search, custodial remands and the make-up of the prison population itself with 32% of all children in prison being black.{{cite web |title=Ethnicity and the Criminal Justice System, 2020 |url=https://www.gov.uk/government/statistics/ethnicity-and-the-criminal-justice-system-statistics-2020/ethnicity-and-the-criminal-justice-system-2020 |website=gov.uk |publisher=Ministry of Justice}}

=Religious group=

In the two decades since 2002, the proportion of Christian prisoners has fallen, by 14%, to 44% of the incarcerated population meanwhile the proportion of Muslim prisoners has risen, by 10%, to 18%. Other religious groups did not see a significant change in proportion. Beginning in 2008, concerns over the spread of Sharia in British prisons, including the operation of Sharia courts and the forced conversions of non-Muslims, have been reported.{{cite news |last1=Doward |first1=Jamie |title=Muslim gangs 'are taking control of prison' |url=https://www.theguardian.com/society/2008/may/25/prisonsandprobation.ukcrime |work=The Guardian |date=25 May 2008}}{{cite news |title=Muslim gangs imposing sharia law in British prisons |url=https://www.telegraph.co.uk/news/uknews/law-and-order/7428933/Muslim-gangs-imposing-sharia-law-in-British-prisons.html |work=The Telegraph |date=15 March 2010}}{{cite news |title='Sharia courts' in British prisons |url=https://www.bbc.co.uk/news/av/uk-36437686 |work=BBC News |date=2 June 2016}}{{cite news |title=End of Sharia courts in jail: Crackdown on terrorists radicalising prisoners behind bars |url=https://www.lbc.co.uk/news/terrorists-banned-from-socialising-sharia-court-prison/ |work=LBC |date=27 April 2022}} According to the UK prison officers' union in 2013, some Muslim prisoners in the UK had allegedly forcibly converted fellow inmates to Islam in prisons.{{cite news |last=Withnall |first=A. |url=https://www.independent.co.uk/news/uk/home-news/britain-s-jails-facing-growing-problem-of-forced-conversion-to-islam-officers-warn-8892645.html |title=Britain's jails facing 'growing problem' of forced conversion to Islam, officers warn |work=The Independent |location=UK |date=20 October 2013}} There have been multiple cases of non-Muslim prisoners threatened with violence{{Cite news |last=Ford |first=Richard |date=7 June 2019 |title=Muslim gangs 'beat prisoners' who will not convert to Islam |newspaper=The Times |language=en |url=https://www.thetimes.com/uk/law/article/muslim-gangs-beat-prisoners-who-will-not-convert-to-islam-gcb8nb2md |access-date=23 April 2022 |issn=0140-0460}} with "convert or get hurt" being a commonly used phrase by Muslim gangs according to an independent report published by the government.{{cite web |last1=Bloom |first1=Colin |title=Does government 'do God?'

Some prisons have been unable to cope with the rise of Islamic gangs, and have opted to place threatened inmates into isolation units for their own safety. Other reasons why inmates may convert include wanting protection in wings where Muslim gangs are prevalent, the ability to go to chapel, and access to different foods. Around 1 in 5 Muslim prisoners in the UK are now white.{{cite news |title=One in five Muslim prisoners is white as ‘gangs drive conversions’ |url=https://www.telegraph.co.uk/news/2024/03/19/one-five-muslim-prisoners-white-islamic-gangs-conversions/ |work=The Telegraph |date=19 March 2024}}

* 2021 ONS Estimate

In 2024, The Telegraph conducted analysis of Ministry of Justice data on foreign nationals alongside recent census data and found that 1 in 50 Albanians in the UK were in jail. Albanians had the highest imprisonment rate, followed by Kosovans, Vietnamese, Algerians, Jamaicans, Eritreans, Iraqis and Somalis. Conversely German, Italian, Indian, Greek, US, Sri Lankan, French and Chinese nationals were the least likely nationalities to be in prison. Overall, the imprisonment rate of foreign nationals was 27 per cent higher than for British citizens.{{cite news |last1=Hymas |first1=Charles |last2=Butcher |first2=Ben |title=Revealed: First migrant crime table |url=https://www.telegraph.co.uk/news/2024/10/04/one-in-50-albanians-uk-in-prison-telegraph-analysis/ |work=The Telegraph |date=4 October 2024}}

Children and young people aged under 18 are not sent to adult prisons if they are sentenced to custody.{{Cite web|url=https://www.gov.uk/young-people-in-custody|title=Young people in custody|website=Gov.uk|access-date=31 March 2019}} They either go to young offender institutions (for prisoners aged 15–21), secure training centres (for those aged under 17) or secure children's homes (for those aged under 15).

The number of children in custody has declined since mid-2008, from more than 3,000 to about 900 at any one time.{{Cite web|url=https://www.theguardian.com/uk-news/2019/feb/28/children-in-young-offender-institutions-at-risk-of-abuse-inquiry-finds|title=More than 1,000 claims of child sexual abuse in custody, inquiry reveals|last=Robert Booth|first=Eric Allison|date=28 February 2019|website=The Guardian|access-date=31 March 2019}} In 2019 an independent inquiry into child sexual abuse published a report that described the scale of alleged abuse in young offender institutions and secure training centres as “shockingly high”.

The number of British prisoners over 60 years of age rose by 130% between 2002 and 2013, a shift attributed to an increase in the convictions for historic sex abuse. The increase was reported after the 2012 commencement of Operation Yewtree, a police investigation into sexual abuse allegations—predominantly the abuse of children—against the British media personality Jimmy Savile and others. In relation to over 4,000 over-60 prisoners in UK prisons, Professor David Wilson of Birmingham City University stated in July 2014:

Four out of 10 of these prisoners (the over-60s) were convicted of sex offences and people over 60 are the fastest growing age group in the prison estate, yet there is no national strategy for the elderly who get sent to prison ... The Prison Service needs to develop a strategy to cope with this fastest growing section of the prison population or they will simply be failing in their duty of care to the elderly people that they are locking up.{{cite news|author1=Jamie Doward and Gaby Bissett|title=Rolf Harris leaves behind gilded lifestyle for vulnerable prison unit|url=https://www.theguardian.com/uk-news/2014/jul/06/rolf-harris-prison-unit|access-date=7 July 2014|work=The Guardian|date=6 July 2014}}

In 2018 there were more than 1,500 prisoners over 70, including more than 200 aged over 80, creating increasing demands on health and social care systems.{{cite news|title=Could elderly prisoners move into secure care homes?|url=https://insidetime.org/could-elderly-prisoners-move-into-secure-care-homes/|access-date=14 February 2018|publisher=Inside Time|date=30 January 2018}}

Women with a child aged under 18 months old may apply to bring their child into prison with them, if they are serving a short sentence.{{Cite web|url=https://www.gov.uk/life-in-prison/pregnancy-and-childcare-in-prison|title=Prison Life|website=Gov UK|access-date=31 March 2019}} Women who give birth in prison may keep their baby for the first 18 months in a mother and baby unit.

Prison population

=Veterans=

A growing number of British prisoners are former armed forces members. According to a study reported in the Guardian in 2009, 8500 former servicemen were imprisoned, making up almost 10% of the prison population.

=Scotland=

Scotland recognized the growth in the prison population and acted accordingly to make adjustments to how the law was carried out so that the system operates efficiently. One of the actions made was to decrease the number of stop-and-searches and between the period of June 2015 and August 2016, there was reportedly an 81% decrease in those actions when statistics from 2014 were compared.Who’s in Prison?

The proportion of prisoners developing a drug abuse problem while incarcerated rose from 8.4% in 2013-2014 to nearly 15% in 2018–2019. Much of the prison system is badly equipped to disrupt illegal drug supply and security standards vary between prisons. Reform maintains prisons are overcrowded, staff retention is poor and using community sentences instead of prison for minor offenses would help. Aidan Shilson-Thomas of Reform said, “There must always be a place in prison for those who commit serious crimes. However, prison must also be an opportunity for inmates to change their behaviour. Stabilising the system means stemming the flow of drugs, reducing overcrowding, fixing the crumbling estate and improving officer retention. Its long-term sustainability requires a serious conversation about how many people we lock up and for how long. Failing to act will mean poorer social outcomes, more reoffending and ultimately huge costs to the taxpayer.”{{cite news |url=https://www.theguardian.com/society/2020/jan/20/proportion-of-uk-prisoners-with-drug-problem-doubles-in-five-years-study |title=Proportion of UK prisoners with drug problem doubles in five years – study |date=2020-01-20 |work=The Guardian }}
