UK Immigration Returns Statistics — Source: Home Office, MoJ, ONSThe Gap: Arrivals vs Returns
Non-visitor visa grants compared to total returns, 2005–2025How Many Arrive vs How Many Leave (2005–2025)
The blue line (left axis) shows the total number of non-visitor visas granted each year. The red line (right axis) shows total returns. Note the different scales: arrivals are measured in hundreds of thousands, returns in tens of thousands. Even with both lines given their own scale, the trends tell the story: arrivals surged post-2021 while returns flatlined. Hover over any year to see the exact ratio.

Data Sources & Coverage
Data Limitations & Caveats
- Nationality, not ethnicity. These datasets use nationality (country of citizenship), not ethnicity or race. Nationality is not a proxy for ethnicity.
- "Returns" includes many outcomes. The figures include deportations, administrative removals, voluntary departures, and port refusals. Not all are forced removals.
- No individual-level linking. Prison population and deportation data cannot be linked at the individual level. All cross-references are aggregate correlations.
- Correlation, not causation. A high prison population relative to deportations does not imply those individuals should or could be deported. Legal proceedings, asylum claims, country cooperation agreements, and many other factors determine deportation outcomes.
- Prison population is a snapshot. It measures who is in prison at a point in time (stock), not how many entered or left (flow). Direct comparison with annual returns is approximate.
- Age-sex adjustment matters. When adjusted for the younger, more male demographic profile of foreign nationals, non-UK nationals are slightly underrepresented in prison overall (Migration Observatory, Sept 2025). Raw numbers overstate the difference.
- Conviction data covers ~30% of all convictions. The PNC data from CMC FOIs covers indictable/CPS-prosecuted cases only, not summary offences. It is not representative of all crime.
- Population denominators are uncertain. For small nationalities (Afghan, Eritrean), ONS population estimates may understate the actual population by 2-3x, which inflates per-capita rates.
- Language does not equal nationality. Court interpreter bookings for Arabic span 20+ countries. Pashto covers both Afghan and Pakistani Pashtun communities.
- Unknown nationality records. 4-8% of conviction records have unknown nationality. If these are disproportionately foreign, the published foreign national share is understated.
