UK Migration Figures: Latest Net Migration Statistics and Trends
The UK's migration landscape has shifted dramatically in recent years, with net migration figures reaching record highs before showing signs of decline. Whether you're a researcher, policymaker, or simply trying to understand how many people are arriving in and leaving the country, the data tells a compelling story. This article breaks down the latest estimates, explains how they're measured, and explores what's driving the numbers.
UK net migration figures: headline numbers for 2023–2024
Provisional estimates from the Office for National Statistics put net migration to the UK at 728,000 in the year ending June 2024. That's a significant fall from the revised figure of 906,000 for the same period in 2023, representing roughly a 20% year-on-year decline.
Net migration is the difference between long term immigration (people coming to the UK for 12 months or more) and emigration (people leaving for the same period). It remains the single largest driver of UK population growth. In fact, migration now accounts for roughly 97% of the UK's population growth.
Despite the fall, these migration figures remain historically high. Before the pandemic, net migration had been stable since 2015, sitting at around 280,000. The post-2021 surge was unprecedented.
Here's how the numbers compare across recent years:
Period (Year ending) | Net migration estimate |
|---|---|
YE June 2019 | ~248,000 |
YE June 2021 | ~488,000 |
YE March 2023 | ~944,000 |
YE June 2023 (revised) | ~906,000 |
YE June 2024 | ~728,000 |
YE December 2024 | ~331,000 |
YE December 2025 | ~171,000 |
These are national statistics classified as experimental or provisional. The ONS notes that figures may be revised as more complete administrative data become available, so treat recent periods as early estimates subject to change.
How the ONS measures international migration and net migration statistics
UK migration statistics are compiled by the Office for National Statistics using a blended approach that combines multiple data sources. This represents a major shift from the past, when estimates relied heavily on the International Passenger Survey - a sample survey of travelers at ports and airports.
The ONS now draws on Home Office Borders and Immigration data, visa records, and Higher Education Statistics Agency data on international students. These administrative sources allow analysts to track actual arrivals, departures, and visa transitions rather than relying on travelers' stated intentions.
At the centre of this system is the concept of Long-term International Migration. Under the UN definition, a long-term migrant is someone who changes their country of usual residence for 12 months or more. Immigration counts those arriving; emigration counts those departing. Net migration is simply the difference.
Recent methodological work includes admin-based migration estimates and a dynamic population model designed to improve coherence between population and migration data. Net migration figures for EU citizens, non EU nationals, and British nationals are each estimated using different types of combinations of survey and administrative sources, reflecting the varying data available for each group. Short term visas and temporary movements are excluded from LTIM estimates but may appear in other sources.
These statistics are produced to professional standards independent from political influence, even as methods continue to evolve.
What is driving higher net migration? Key reasons since 2021
Since 2021, net migration has been elevated due to a combination of policy changes, post-pandemic recovery, and international crises. Understanding these drivers is essential to making sense of the headline figures.
The end of free movement for EU citizens after Brexit reshaped the immigration system. The UK introduced a points-based system that shifted emphasis toward non EU skilled work and study routes. EU migration fell - or turned negative - while non-EU arrivals surged.
One-off humanitarian factors also played a role. Ukraine visa schemes and the Hong Kong BN(O) route brought tens of thousands of people to the UK in 2022 and 2023. These crisis-driven arrivals pushed figures higher during peak years.
Structural drivers matter too. Strong demand for UK higher education expanded the study route. Health and Care Worker visas, introduced to address acute NHS and care sector shortages, grew rapidly from 2022. Work visas across skilled routes also increased.
Emigration has risen - long-term emigration in 2025 was about 642,000, slightly down from 680,000 in 2024 - but not enough to offset the surge in immigration during this period. Many of those who arrived as students in 2021–2022 are now completing courses and departing, which is reflected in rising emigration from that cohort.
Some of these influences may taper. Humanitarian routes are time-limited. But others - an ageing population, persistent skill shortages - provide ongoing upward pressure on international migration.
Visa routes and reasons for migration: work, study, family and humanitarian
Gross long term immigration to the UK reached 1.2 million in the most recent 12-month period, with the large majority arriving via non-EU routes. The data published by ONS and the Home Office allow us to explore exactly why people are coming to the UK.
The main reasons break down as follows for non-EU+ nationals in YE June 2024:
Work (main applicants): ~184,000
Work dependants: ~233,000
Study (main applicants): ~295,000
Study dependants: ~80,000
Family: ~76,000
Asylum: ~84,000
Humanitarian/resettlement: ~67,000
Dependants are a major factor. In work related reasons, dependants actually outnumber main applicants. Around 80,000 migrants came to the UK as student dependants in 2023, down from approximately 115,000 the year before - a direct outcome of new policy restrictions.
Asylum claims remained elevated, with about 86,000 applications by June 2026, though this was down 21% year-on-year. Humanitarian and asylum routes account for a smaller share of total international migration than work or study, yet they receive disproportionate media and political attention.
The role of international students in UK migration figures
The ONS international students update releases - including new analysis published in November 2024 - have made clear that students are central to current migration debates. Jay Lindop, deputy director at ONS, has highlighted how different types of measurement can lead to very different conclusions about students' long-term contribution to net migration.
Most international students are non EU migrants. In 2023, 263,000 non-EU nationals arrived on study-related visas. About 294,000 non EU nationals arrived in the UK for study in 2025, a 7% increase from the previous year.
Net migration from international students rose from 24,000 in 2019 to 263,000 in 2023 - a dramatic rise driven in part by the post-study Graduate visa route.
The ONS uses three main methods to assess student impact:
Net migration by initial reason: Tracks flows by the visa category people first arrive on.
Cohort method: Follows a specific cohort (e.g. those whose visas ended in 2018–19) to measure the outcome - around 61% left at the end of their visa.
Adjustment method: Adjusts flows by observed retention and transitions to other visa types over time.
The data show that 35% of international students applied for new visas after studies in 2019. However, only 17% of the 2018 cohort remained in the UK five years after their initial arrival. So while the arrivals figures are large, many students leave after their course ends. Their long-term contribution to net migration is smaller than the raw immigration numbers suggest.
EU citizens versus non-EU nationals: shifting patterns after Brexit
The balance between EU and non EU migration has flipped since Brexit. Before 2016, EU migrants drove a large share of net migration, supported by free movement from across Europe. That era is over.
In ONS migration data, "EU+" includes EU countries plus Norway, Iceland, Liechtenstein, and Switzerland. Non EU covers all other nationalities. British nationals are reported separately.
In YE June 2024, 86% of migrants to the UK were non-EU nationals. Non-EU+ net migration stood at roughly +845,000, while EU+ net migration was estimated at –95,000. Negative net migration for EU nationals was estimated at –42,000 in 2025.
Non-EU immigration accounted for around 77% of all immigration in 2025. EU citizens still arrive, but at far lower net levels than in the mid-2010s. The tens of thousands who once came from Europe looking for work have been replaced by non EU migrants on skilled worker, study, and family routes.
Nationality group | YE June 2024 net migration |
|---|---|
Non-EU+ | +845,000 |
EU+ | –95,000 |
British nationals | –21,000 |
This shift means that policy changes to non-EU routes are now the primary lever for any government aiming to reduce net migration figures.
Policy changes and the future of the UK immigration system
High net migration statistics have triggered significant political debate and a series of reforms from late 2023 onwards. The government has targeted the specific categories that drove previous increases.
Key changes include:
Student dependants restricted (January 2024): Most overseas students can no longer bring family members, contributing to a sharp fall in study dependant arrivals.
Salary thresholds raised (April 2024): The minimum income requirement for sponsoring a spouse or partner rose from £18,600 to £29,000.
Health and Care Worker dependants limited and Skilled Worker salary floors increased.
These reforms appear to be having measurable effect. Work-related immigration saw a 47% reduction among non-EU+ nationals in 2025 compared to the previous year. Long-term immigration to the UK was approximately 813,000 in 2025, down 20% from 2024. UK net migration for the year ending December 2025 fell to 171,000. The substantial drop in net migration in 2025 is primarily driven by fewer non-EU work-related arrivals and higher emigration. Tighter work-visa rules and changing labor demand have reduced non-EU work migration, which had been the largest component of net migration.
The principal driver of the decline was the fall in non-EU immigration, particularly work-related migration and dependents.
Previous attempts to reduce net migration via fee increases and surcharges have had limited long-term impact, especially where UK employers face persistent labour shortages in sectors like health and social care.
Readers should monitor upcoming ONS releases and Home Office visa statistics for evidence of how quickly these reforms affect the numbers in each quarter.
Economic and social impacts of current UK migration figures
Migration is the major driver of UK population change. Approximately 19% of the UK population is foreign-born, totaling around 13.1 million people. Over 40% of London's population was born overseas, reflecting the capital's role as a global gateway.
The positive contribution is substantial. Migrants fill critical jobs in health, social care, technology, and higher education. In 2022, international students contributed over £22 billion to the UK economy through tuition fees, local spending, and employment. Working-age migrants support public finances and help mitigate the fiscal effects of an ageing population.
Pressure points are real too. High net migration amplifies demand for housing - particularly in regions already stretched. NHS capacity, school places, local transport, and integration services all come under strain when arrivals rise sharply in a short period.
The NHS provides a clear case study. Tens of thousands of health and care workers arrived through dedicated visa routes from 2022 onwards, filling vacancies that domestic recruitment had failed to address. Without this migration, staffing shortages across hospitals and care homes would have been far more acute.
Impartial national statistics allow policymakers and the public to assess these trade-offs clearly, distinguishing between temporary migrants - like many students - and longer-term settlers whose impact on local services and the labour market is more lasting.
Understanding and using UK migration statistics: data sources and further information
For anyone looking to access authoritative migration data, the ONS publishes several key outputs. The Long-term International Migration provisional estimates (released for periods ending June and December) provide the headline net migration figures. The Reason for International Migration reports, including the international students update series, offer deeper analysis of who is arriving and why. Articles on admin-based migration estimates explain how methods are evolving.
Home Office quarterly and annual Immigration Statistics provide complementary data on visas granted, asylum decisions, and enforcement outcomes - published today and updated regularly on gov.uk.
Limitations remain. Provisional data are subject to revision. Coverage gaps exist for short-term migrants and certain nationality groups. Matching across administrative datasets introduces uncertainty. It's worth distinguishing between national statistics produced by the ONS - compiled independently using rigorous methodology - and more selective uses of the same data in political or media debate.
The aim should always be to consult original releases before drawing conclusions. Migration is too important a topic to rely on second-hand summaries when the full report is freely available.
