The ONS estimates that the UK population increased by 228,000 between mid-2024 and mid-2025. Births only outnumbered deaths by 5,000. As a result, migration accounted for 98% of the increase (223,000). Here's the full publication 👉 www.ons.gov.uk/peoplepopula...

In July, 43% of the public said immigration was an important issue affecting the UK, more than any other topic. Take a look at our updated public attitudes briefing to see how views vary towards different migrant groups and who is more likely to hold positive/negative attitudes toward immigration.

Reports that small shops and takeaways have hired migrants on Skilled Worker visas have appeared in several media outlets recently. Our new Q&A explains why these employers were able to sponsor migrants, how many actually did, whether the government could ban them from using the visa system + more.

The government does not publish data on the share of foreign national offenders (FNOs) who are deported. However, the number of FNOs living in the community has increased over the past decade, suggesting that returns have not kept pace with prison releases.

Non-citizens are less likely to receive bail than citizens and so are overrepresented in the population of people on remand awaiting trial. Around 25% of non-citizens in prisons had not yet been tried, compared to 11% of British citizens.

Migration Observatory @migobs.bsky.social · 18/08/2026
Non-citizens were more likely to be convicted or incarcerated for drug offences and less likely for violent offences than British citizens The picture is more complicated for sexual offences—they are overrepresented among convictions but underrepresented in the prison population

Offending varies by nationality. This is to be expected because people from different backgrounds will have different risk factors (e.g socioeconomic deprivation) The most common non-UK nationalities in English and Welsh prisons at the end of 2025 were Albanian, Irish, & Polish.
120
Migration Observatory @migobs.bsky.social · 18/08/2026
The share of non-citizens among people in England and Wales prisons is lower when age is taken into account. This is because non-citizens tend to be younger, and criminal offending takes place primarily among young men.

Migration Observatory @migobs.bsky.social · 18/08/2026
Non-UK citizens made up 13.1% of people given cautions or convictions in 2024 and 12.1% of the prison population in June 2025. This was similar to their share of the 16+ population

We've updated our briefing on migrants and crime in the UK It looks at whether foreign nationals are more or less likely to be convicted than British citizens, and how many foreign national offenders are removed after serving their sentences Here are the key points.

Sectors that hire migrant workers on the TSL will be required to increase their use of the domestic workforce. Will it work? Possibly, but the MAC highlights two key challenges:

The Migration Advisory Committee has published its recommendation on which middle-skill jobs should be eligible for temporary work visas via the Temporary Shortage List. The headline? Welders and other more technical jobs are in. Jobs that are more generic (e.g., Business sales executives) are out.

In 2025, just over 100,000 people claimed asylum in the UK. Our updated briefing explains who claims asylum, how these people come to the UK, whether their claims are successful, and much more. migrationobservatory.ox.ac.uk/resources/br...

OBR forecasts have generally estimated that higher migration leads to (slightly) lower deficits and debt. How much, though, depends on whether governments use the additional tax revenue to increase public service spending to reflect a bigger population.

Migrants' fiscal impact changes over time. They are more positive in the years after they arrive, but their contribution falls over time. This is because, later in life, people incur more public spending – particularly on healthcare and pensions. E.g. main applicants on health and care visas...

Broadly speaking, migrants working in jobs towards the top of the skill and salary spectrum bring a net fiscal benefit, while people who are out of work or use more public services have a net negative impact.

The Committee was critical of the UK’s migration data. It recommended that the government link visa records to employment, benefit, and public services data to better understand the outcomes of migrants on different visa routes.

The Committee recommended that MAC advise on the income levels that lead to a reduction in routes to ILR, which it says should be based on migrants’ net fiscal impact rather than income tax thresholds. It also said income levels should be assessed at the household level in some cases.

Migration Observatory @migobs.bsky.social · 24/06/2026
On the earned settlement, a majority: - Supported the introduction of mandatory requirements to acquire ILR (regardless of time on a qualifying visa). - Opposed extending the qualifying period for ILR beyond 5 years. - Opposed retrospection for migrants already on a route to settlement.

68% of the increase in the UK’s population growth between 2005 and 2024 was due to net migration, and ONS projections assume this will rise to 144% in the coming years—in other words, the population would decline without net migration. See our updated briefing for more.

ONS significantly downgrades UK population growth forecast on the back of falling net migration - with net migration central estimate reduced from 340k per year to 230k (means population of the UK would hit 71m by 2034, rather than 72.2m, as projected in 2022)

Home Office monthly stats are out today.The data show that applications for Health & Care and Skilled Worker visas continue to fall. Meanwhile, the share of dependants is rising in both routes, even after restrictions on H&C dependants. What’s driving this trend is not entirely clear. Any thoughts?💡

80k asylum appeals were pending at the end of 2025, double from a year before. Initial decision backlog has fallen but a growing appeals backlog means the number of asylum seekers receiving support - and in hotels - remains high. Our updated tracker of Labour's goals:

How will the higher language requirement affect migrants? In short, we don’t know because there's no data on how many migrants can speak English at the B1 or B2 level. In 2021, however, 90% of migrants living in England or Wales self-reported speaking English without difficulty.
100
Migration Observatory @migobs.bsky.social · 11/03/2026
The government has announced that migrants will have to pass an English language test at the B2 level to obtain settlement, up from the current B1 level. This change will come into force in March 2027.

The government will stop issuing study visas to people from 4 countries, plus Skilled Worker visas to Afghans. It said this is because people from those countries were the most likely to make an asylum claim after coming to the UK to study. In 2025, there were 3,209 grants to affected nationals 👇

New ONS data: % of intl students who stay in the UK has continued to increase. More are switching to other visas - 2 yrs after arrival, 62% of students who arrived in YE June 2023 had switched, up from 17% among YE June 2020 arrivals. Our previous analysis on this linked below

Migration Observatory @migobs.bsky.social · 25/02/2026
Settlement rates are expected to increase. One indication is that 82% of migrants who arrived in 2022 still had leave 2 years later, the highest share of any cohort in the past 20 years. This is before we consider the impact of govt's earned settlement proposals, which will reduce settlement rates.
110
Migration Observatory @migobs.bsky.social · 25/02/2026
The majority of non-EU migrants who arrived during the past two decades did not go on to acquire settlement. Settlement rates were much higher for family migrants (approx. 80%) than for work migrants and students (approx. 25% and 15%, respectively).

A Times investigation has found that visa agents are selling Skilled Worker visas for positions that don't exist. It's well worth reading the full article (link in the next post), but here's how it works.

Family visa applications stabilised again in December after falling sharply in the last quarter of the year. This category includes Family Reunion for refugees, which was paused in September 2025, explaining the abrupt fall.

There was a small uptick in skilled worker and health and care visa applications in December, after an overall downward trend throughout the year as a whole. It's worth noting, as of July 2025, care workers are no longer eligible to apply for the health and care route.

The MAC highlight research which finds a link between migrant integration and proficiency in the host country's language. In the 2021 Census, most migrants reported speaking good English, but 10% said they cannot speak English well or at all.

The MAC estimates that the average partner who came to the UK on a family visa in 2022/23 will represent a net cost of £109,000 over their lifetime. Their annual fiscal impact is positive for many years after arrival, but falls significantly as these people grow older.

Overseas Domestic Workers are, e.g., nannies, housekeepers, and chauffeurs who accompany their employers when they visit the UK. ODWs are vulnerable to exploitation. This abuse often takes place behind closed doors, which can make enforcement difficult.
