Key Takeaways
- Net migration to the UK fell sharply from a peak of 944,000 (year to March 2023) to 204,000 (year to June 2025), the lowest level in years.
- Despite the decline, 67 % of immigration‑sceptics and 60 % of those who want reduced immigration still believe net migration is rising.
- The public vastly overestimates the share of asylum seekers (33 % perceived vs. 9 % actual) and underestimates the share of students (24 % perceived vs. >50 % actual).
- Perception gaps fuel a polarised immigration debate, with politicians across parties using increasingly hostile rhetoric even as numbers fall.
- Immigration ranks as the third‑most important public issue (after cost of living and the NHS), but concerns are often tied to broader anxieties about security, stability, and trust in the system.
Overview of British Future’s Research Findings
British Future’s latest study, released ahead of the government’s official migration statistics, highlights a striking disconnect between public perception and actual net‑migration trends. The think‑tank surveyed a nationally representative sample of 3,003 adults in Great Britain at the end of March and found that a substantial majority believes net migration has increased in 2025, even though government data show a steep decline. This perception gap is not merely a statistical curiosity; it shapes the immigration debate, influences political rhetoric, and affects voter attitudes across the spectrum.
Net Migration Figures Show a Sharp Decline
According to the Office for National Statistics, net migration peaked at 944,000 in the year to March 2023. By the year to June 2025, the figure had fallen to 204,000—a reduction of roughly 78 %. The upcoming release of the latest figures is expected to confirm a further decrease, marking the lowest annual net‑migration level since 2021. Home Secretary Shabana Mahmood acknowledged this 69 % drop in the 12‑month period to June 2025, noting that while the numbers are down, the pace and scale of migration continue to exert pressure on local communities.
Public Perception Divided by Political Outlook
The research reveals a clear divide in how different groups interpret the data. Among respondents who hold sceptical views on immigration, 67 % believe net migration rose in 2025. In contrast, only 37 % of those with more liberal immigration views share that belief. Even among people who explicitly want immigration reduced, six in ten still think numbers are rising. Only 15 % of the overall sample anticipate net migration to be lower in the coming year, underscoring the persistence of the misperception.
Misunderstanding the Composition of Immigration
Beyond overall numbers, the public misjudges the makeup of immigration flows. Respondents estimated that asylum seekers account for 33 % of all immigrants, whereas the actual share is about 9 %. Conversely, they believe students make up just 24 % of immigrants, while in reality students represent just over half of all incoming migrants. These misconceptions amplify fears about uncontrolled arrivals and obscure the significant role of legal, study‑related migration in the UK’s demographic picture.
Perception Gap Fuels the Immigration Debate
Sunder Katwala, director of British Future, warned that the perception gap helps explain why voters think net migration is rising when the dominant political conversation focuses solely on how to bring it down. He argued for a shift toward discussing how to manage both the pressures and the benefits of migration, rather than treating the issue as a zero‑sum game. The mismatch between reality and perception, he suggests, hampers constructive policy‑making and fuels unnecessary anxiety.
Brexit‑Era Polarisation and Party Rhetoric
Since the Brexit referendum, immigration discourse has become increasingly polarised. Slogans such as “stop the boats” and repeated pledges to curb unauthorised Channel crossings have entered the mainstream, shaping attitudes across party lines. Guardian analysis shows that Labour and Conservative MPs have spoken about immigration with greater hostility in the past five years than at almost any other point in the last century. British Future’s findings confirm that mistrust of immigration is now shared across the political spectrum, despite the objective decline in net migration.
Political Responses to the Declining Figures
In reaction to the latest data, Home Secretary Shabana Mahmood conceded the 69 % drop but argued for further action, citing local‑community pressures. Shadow Home Secretary Chris Philp countered that the government needs to go “much further” in restricting migration. Reform UK has pledged to achieve “net zero” immigration, with its leader Nigel Farage falsely attributing the recent decline to British emigration rather than reduced overseas arrivals. These contrasting statements illustrate how parties use the same statistics to advance divergent policy narratives.
Immigration’s Place in Public Concerns
Immigration ranks as the third‑most important issue for the British public, trailing only the cost of living and the NHS. Sophie Stowers, a research manager at More in Common, notes that visceral images—such as small‑boat arrivals and asylum hotels—often dominate public perception more than abstract statistical trends. She observes that net migration or legal migration is only part of the story; voters’ concerns frequently stem from broader feelings about security, stability, and trust in governmental institutions.
Wider Anxieties Behind Immigration Concerns
Stowers argues that anxieties about immigration and small boats are proxies for deeper uncertainties in an increasingly volatile world. When people question whether the system is working, immigration becomes a convenient focal point for those doubts. Consequently, merely presenting data showing a fall in net migration does little to shift public opinion unless the underlying sense of insecurity and systemic efficacy is also addressed.
Methodology and Future Outlook
The British Future survey employed Number Cruncher Politics to poll 3,003 adults across Great Britain at the end of March, ensuring a robust, nationally representative sample. The report warns that if current trends continue, all major parties may confront a markedly different immigration context by the time they prepare for the 2029 general election campaign. Policymakers will need to reconcile the objective decline in migration with the persistent public belief that numbers are rising, lest the debate remain detached from reality.
Conclusion: Bridging the Gap Between Data and Perception
The British Future research underscores a critical challenge: public opinion on immigration is out of step with empirical evidence. While net migration has fallen dramatically, misperceptions about its scale, composition, and drivers remain widespread, influencing political rhetoric and voter behaviour. Addressing this gap requires not only clearer communication of factual trends but also a broader conversation about the social, economic, and security dimensions that underlie public concerns. Only by aligning perception with reality can the UK develop immigration policies that are both effective and publicly legitimate.
