Crime & justice

What the crime data can honestly tell you, and what it cannot.

What the crime data can honestly tell you about immigration, and what it can't. No invented statistics, in either direction.

Foreign nationals in prison ≈12%

Crime rates by immigration status Not published
The evidence

16 figures, each with its official source.

8.5%
Crimes that end in a charge or summons

447,514 charges or summonses against 5.2 million recorded offences. Rising: the rate was 6.4% in the year to March 2024 and 7.3% the year after. Police recorded crime is not designated as Accredited Official Statistics.

≈12%
Foreign nationals in prison (share)

A composition share, NOT an offending rate. Inflated by high remand (3,588 of 10,487 were unconvicted), serious-offence/long-sentence mix, and deportation holds. It does not measure propensity to offend.

10,487
Foreign nationals in prison (count)

3,588 on remand, 6,458 sentenced, 441 non-criminal. A raw count is not a rate, no population denominator, no controls for age/sex/remand.

≈10%
Foreign nationals in the population (fair comparator)

Non-British citizens, the like-for-like comparator. Comparing ~12% prison vs ~10% population does NOT reveal an offending gap: prisons skew to working-age men, remand and long sentences; the population includes children and the elderly.

Migration Observatory (Oxford)by nationality, Census 2021
Albanian, Irish, Polish
Largest foreign nationalities in prison

Albanian ~9% · Irish ~7% · Polish ~7% · Romanian ~6% · Indian ~4% Shares WITHIN the foreign-national prison group. Several are large UK migrant communities, bigger communities contribute more to every count; this reflects community size, not offending propensity.

Largely no, not published
Are crime rates by immigration status published?

Largely no, the UK does not hold breakdowns of crime by migrant or asylum status The single most important fact here: because there is no reliable offending rate by immigration status, any claim that migrants offend more (or less) than others cannot be supported by official UK statistics.

Generally no such effect found
What the peer-reviewed evidence finds

Immigration has generally NOT been found to raise crime rates Effects where found are small and shaped by labour-market opportunity, not nationality or ethnicity. No robust evidence immigration systematically raises crime.

Disparities, not propensity
Ethnicity & the justice system, official position

Disparities exist but do NOT establish propensity to offend The government's own statisticians warn disparities reflect confounders, age/sex, deprivation, geography, offence mix, and differential policing, none controlled for. Not evidence of propensity.

Documented, Jay Report 2014
A real, documented phenomenon

Confirmed by the Jay Report (Rotherham, 2014) and reviews into Rochdale, Telford and Oldham The Jay Report estimated ~1,400 children were sexually exploited in Rotherham (1997–2013), with convictions and serious case reviews in several towns. The debate is about national scale and offender characteristics.

12 recommendations, accepted
Baroness Casey's National Audit (2025)

Published 16 June 2025; 12 recommendations, all accepted, including a national inquiry Commissioned by the Prime Minister in January 2025; conducted by Louise Casey, Baroness Casey of Blackstock.

Yes, in 3 force areas examined
Casey: local over-representation

'Disproportionate numbers of men from Asian ethnic backgrounds amongst suspects' in the three force areas examined (Greater Manchester, West Yorkshire, South Yorkshire) A LOCAL finding from three force areas, the same audit stresses national data is insufficient. Both halves matter.

Home Office: Casey auditreported Jun 2025
62% and 52% in two operations
Illustrative local operation figures

W. Midlands operation (2015): 62% of 75 suspects recorded Pakistani, 12% White. Greater Manchester: of 269 known suspects, 52% recorded 'Asian', 38% 'White' These are counts of SUSPECTS (not convicted offenders) in single local operations, small samples, differing definitions, known recording biases. They cannot be added up or generalised; the audit says national ethnicity data is insufficient to draw any conclusions.

Home Office: Casey audit2015 / 2020s, per the 2025 audit
Missing for 2 in 3 cases
Ethnicity data quality

Ethnicity is 'still not recorded for two-thirds of perpetrators' and 'not sufficient to allow any conclusions at the national level' An official warning against drawing national ethnic conclusions from incomplete records.

No national figures exist
Reliable national ethnicity figures?

No, so specific '% Pakistani' figures circulating in the media are not nationally evidenced Improving this data is one of the audit's recommendations; the national inquiry will examine offender ethnicity.

A subset of all child abuse
Broader CSA context

Group-based 'grooming gang' offending is a smaller subset of all child sexual abuse, much of which is online or within families; Home Office analysis recorded most group-based CSE offenders as White Around 40% of police-recorded child sexual abuse (2023/24) was online. The Home Office 'majority White' finding comes with its own data-quality caveats. Context to keep the phenomenon in proportion without minimising it.

Began 31 March 2026
National statutory inquiry

Chaired by Baroness Longfield; began 31 March 2026, up to three years (England & Wales) Powers to compel evidence; national hearings plus local investigations (incl. Oldham, Bradford, Keighley). Remit includes offender ethnicity and why data has been so poor.
