Britain's Great Exchange
Net migration 'fell' to 171,000 last year. Beneath the headline, Britain lost a net 136,000 of its own citizens — and gained 350,000 from beyond Europe.
The number that led the bulletins was a fall. Net migration in the year ending December 2025 came in at 171,000 — well down from the post-Brexit peaks, and duly reported as a system being brought under control. It is a true figure. It is also one of the least informative single numbers the migration statistics produce, because a net figure is a subtraction, and a subtraction conceals everything that went into it.
Pull the two halves apart and a different picture emerges. 813,000 people arrived for the long term; 642,000 left. The net of those flows is small. The flows themselves are not. And once you split them by citizenship, the headline stops describing a slowdown and starts describing a substitution.
The ledger
The single most useful table the Office for National Statistics publishes is the breakdown of immigration, emigration and net flow by citizenship group. Read down the columns rather than across the headline.
| Flow | Total | British | EU+ | Non-EU+ |
|---|---|---|---|---|
| Immigration | 813,000 | 110,000 | 76,000 | 627,000 |
| Emigration | 642,000 | 246,000 | 118,000 | 278,000 |
| Net | +171,000 | −136,000 | −42,000 | +350,000 |
Two of the three citizenship groups ran a net loss. British citizens: minus 136,000. EU+ nationals: minus 42,000. The only group adding to the population was the non-EU+ group — and it added 350,000 net, more than twice the entire headline figure. The net total of 171,000 is not a balance struck across the board. It is one large positive flow, partly masked by two negative ones.
Who left
A quarter of a million British citizens — 246,000 — emigrated for the long term last year. Only 110,000 came back. The country ran a net loss of its own people for the second year running, and at a scale that would, in any other column, be treated as a story in itself.
The European unwind continued in parallel. EU+ emigration reached 118,000, the bulk of it — around 100,000 — people leaving the EU Settlement Scheme rather than fresh visa-holders. The departures were concentrated among the nationalities that defined free-movement-era migration.
The Poles and Romanians who arrived in the 2000s and 2010s are now, on these numbers, a population in retreat. Whatever replaces them is not coming from Europe.
Who arrived
Of the 813,000 long-term arrivals, 627,000 — more than three in four — were non-EU+ nationals. The ONS records why they came:
Study is the engine. And a handful of nationalities supply most of the people, with India alone accounting for one in five non-EU arrivals.
| Nationality | Total | Work | Study | Other |
|---|---|---|---|---|
| Indian | 139,000 | 40,000 | 89,000 | 9,000 |
| Pakistani | 56,000 | 12,000 | 33,000 | 11,000 |
| Chinese | 54,000 | 4,000 | 43,000 | 7,000 |
| Nigerian | 47,000 | 10,000 | 34,000 | 3,000 |
| Nepalese | 24,000 | 2,000 | 21,000 | 2,000 |
| American | 20,000 | 8,000 | 7,000 | 4,000 |
| Ukrainian | 17,000 | 0 | 0 | 16,000 |
The student pipeline
The ONS measures population flows; the Home Office measures the visas that authorise them. Its entry-clearance grants for the year ending March 2026 tell the same story from the other end of the pipe — and at greater volume, because a grant is not yet an arrival.
| Visa group | Grants |
|---|---|
| Study | 412,825 |
| Work | 252,775 |
| Other | 70,408 |
| Family | 62,470 |
More than 412,000 study visas were granted in a single year — over 400,000 of them on the sponsored-study route. India (92,000) and China (89,000) supplied nearly half between them, with Nigeria (35,000), Pakistan (27,000) and Nepal (20,000) close behind. On the work side, the Worker route ran to 136,000 grants (India 41,557; Pakistan 11,316; Nigeria 8,575) and a further 83,000 went to the Temporary Worker route, where the leading nationality was, unusually, Kyrgyzstan (14,109).
The student pipeline is not a side channel. It is the principal mechanism by which the non-EU+ inflow is generated.
The churn
What gives the net figure its softness is that the same routes also produce departures. Students, in particular, arrive and leave in great numbers — the ONS records long-term emigration by original reason for immigration, the closest proxy available for “what visa did they hold”. Set inbound against outbound and the difference between a transient flow and a settling one becomes visible.
| Original reason | Inbound | Outbound |
|---|---|---|
| Study | 294,000 | 159,000 |
| Work | 146,000 | 63,000 |
| Asylum | 88,000 | 6,000 |
| Family | 47,000 | 25,000 |
| Humanitarian | 35,000 | 19,000 |
Study churns hardest — 294,000 in against 159,000 out; work and family see large round-trips of their own. Asylum is the exception — and it is where the gap between a decision and a departure is widest.
The Home Office received 93,525 asylum claims in the year to March 2026 and rejected 79,719 of them — roughly five in six. Yet only 3,475 of those refused were deported, and a further 8,443 left voluntarily. Rejection, in practice, is rarely removal.
Widen the lens to the whole system — every route and nationality, not just asylum — and the pattern holds. The Home Office’s returns figures for the year to March 2026 are counted by nationality and return type, and they are dwarfed by the inflow they are meant to offset.
Fewer than 10,000 enforced returns in a year — across every route, not just asylum — against 813,000 arrivals. Voluntary returns, the largest category at 29,284, were led by India (9,473) and Brazil (4,794). The state removes people in the low tens of thousands and admits them in the high hundreds of thousands.
What the exchange means
The honest summary of the year is not “net migration fell”. It is this: Britain exported 136,000 of its own citizens and 42,000 Europeans, and imported a net 350,000 people from outside Europe, the majority of them on student visas from five countries. The headline number is small only because these movements happen to partly cancel in arithmetic. They do not cancel in any other sense. The people leaving and the people arriving are not the same people, do not come from the same places, and will not shape the country in the same way.
A net figure tells you the size of a population change. It tells you nothing about its composition. The composition, this year, is an exchange.
