Nine Million Arrivals, Five Million Departures: How Migration Has Changed Britain – And What It Means for Housing and Public Services
Britain is approaching a significant milestone. With the UK's population now close to 70 million, the country is larger than at any time in its history.
Much of the public debate focuses on small boats crossing the English Channel. Yet the official figures show that this is only one part of a much bigger story.
Over the past decade, around 9.3 million people have moved to the UK for at least a year, while approximately 4.8 million have left. The result is a net increase of around 4.5 million people through migration.
That raises an important question.
Can Britain's housing, NHS, schools and infrastructure keep pace with population growth?
Looking Beyond the Headlines
Migration is often discussed as if it were one single issue. In reality, it consists of several very different groups.
They include:
International students.
Skilled workers.
Doctors, nurses and care workers.
Family members joining relatives.
Refugees arriving through humanitarian schemes.
People claiming asylum.
British citizens returning from overseas.
Overseas workers filling shortages in agriculture, hospitality and construction.
Many eventually return home. Others settle permanently. Each group has a different economic impact.
The Biggest Change Came After the Pandemic
Following COVID-19, migration reached levels few expected.
International recruitment increased sharply as employers struggled to fill vacancies. Universities welcomed record numbers of overseas students. Humanitarian schemes were introduced for people fleeing war in Ukraine, political repression in Hong Kong and conflict in Afghanistan.
The result was record net migration in 2022 and 2023.
Although the numbers have since fallen, they remain historically high.
Housing – The Pressure Everyone Can See
Housing is probably the area where population growth is most visible.
Every additional household needs somewhere to live.
That does not necessarily mean every new arrival immediately requires a newly built home. Many share accommodation, live in university halls or stay with family. Nevertheless, over time, population growth increases demand for housing.
The UK has struggled to build enough homes for decades.
Successive governments have announced ambitious house-building targets, yet completions have frequently fallen short.
This has contributed to:
Rising house prices.
Higher private rents.
Longer social housing waiting lists.
Increased use of temporary accommodation.
Greater competition for affordable homes.
In many rural communities, including parts of the Highlands, the problem is even more complex.
Housing supply is constrained by geography, planning rules, infrastructure and labour shortages. At the same time, second homes and short-term holiday lets reduce the number of properties available for permanent residents.
Migration is one factor increasing demand, but it sits alongside many long-standing structural problems.
The NHS
Population growth inevitably increases demand for healthcare.
More GP appointments.
More hospital treatments.
More prescriptions.
More dental care.
More mental health services.
At the same time, migration has also helped the NHS function.
Thousands of doctors, nurses and healthcare professionals working in Britain today trained overseas.
Without international recruitment, many NHS vacancies would almost certainly have been even harder to fill.
The challenge is therefore two-sided.
Migration increases demand for healthcare while also supplying many of the staff who deliver it.
Schools
Growing populations mean more children requiring school places.
Many areas have expanded schools or built new ones over the past decade.
Where planning has failed to anticipate population growth, local authorities have sometimes struggled to provide sufficient places quickly enough.
Conversely, some rural communities experiencing population decline welcome new families because they help keep village schools open.
The impact therefore varies considerably across the country.
Roads, Transport and Utilities
More people place greater demands upon:
Roads.
Rail services.
Buses.
Water supplies.
Electricity networks.
Waste collection.
Broadband.
These systems generally take years to expand.
Population can often grow much faster than infrastructure.
Universities – A Special Case
International students have become one of Britain's largest export industries.
They contribute billions of pounds annually through tuition fees and spending in local economies.
Many universities now depend heavily upon overseas students to balance their finances.
However, the growth has also created debate.
Some graduates later obtain work visas.
Others return home.
A smaller number claim asylum after entering the UK legally.
Government restrictions introduced in recent years have reduced the number of dependant family members accompanying international students.
The Labour Market
Employers frequently argue that migration fills shortages where insufficient UK workers are available.
Examples include:
Health care.
Social care.
Agriculture.
Hospitality.
Food processing.
Engineering.
Information technology.
Critics respond that easier access to overseas labour may reduce incentives to improve pay, invest in training or encourage more economically inactive people into work.
Both arguments continue to shape political debate.
Tax Contributions
Migrants both pay taxes and use public services.
Whether migration produces an overall fiscal gain depends upon factors including:
Age.
Employment.
Income.
Skills.
Family size.
Length of stay.
Young working migrants generally contribute more in taxes than they receive in public spending during their early years.
Long-term costs and benefits vary considerably between different groups.
Regional Differences Matter
The experience of migration is not the same everywhere.
London and the South East have absorbed large numbers of newcomers for decades.
Some northern and rural communities have seen much smaller changes.
In Scotland, migration has often been viewed differently because an ageing population and lower birth rates create concerns about future workforce shortages.
Yet even within Scotland there are significant regional differences.
Communities such as Caithness face housing shortages, recruitment difficulties and ageing populations simultaneously.
Can Britain Build Fast Enough?
Perhaps the central question is not simply whether migration is too high or too low.
It is whether Britain has expanded housing and infrastructure at the same pace.
Many economists argue that the country has under-invested for decades.
Housebuilding has often lagged behind demand.
Transport projects take years.
Hospitals and GP surgeries require long-term funding.
Schools cannot be built overnight.
As a result, even moderate population growth can create visible pressure if investment does not keep pace.
The Politics
Migration remains one of the most divisive issues in British politics.
Some argue that lower migration would ease pressure on housing, schools and public services.
Others contend that Britain's economy, NHS and universities depend heavily upon overseas workers and students.
The evidence suggests elements of both arguments contain truth.
Migration has undoubtedly contributed to population growth and increased demand for homes and services.
At the same time, many of those delivering healthcare, caring for older people, building homes and supporting businesses are migrants themselves.
Looking Ahead
The Office for National Statistics projects that migration will remain an important driver of population growth for years to come.
If current trends continue, Britain will pass 70 million people in the near future.
The challenge for whichever government is in power will be whether infrastructure grows alongside the population.
Without enough homes, schools, GP surgeries, roads, water supplies and public transport, pressures are likely to continue regardless of where new residents come from.
The debate, therefore, may gradually shift from simply asking "How many people are arriving?" to the equally important question:
"Is Britain planning and investing quickly enough for the population it already has—and the population it expects to have?"
For many people, that may prove to be the defining public policy challenge of the next decade.
Where have immigrants to the UK come from over the last 10 years?
The largest groups have generally been:
1. India – the largest source
India has become the biggest source of long-term immigration to the UK.
Main reasons:
University study.
Skilled work visas.
IT, engineering, finance and healthcare jobs.
Family links.
Recent figures show Indian nationals were the largest non-EU group arriving in the UK, and India has been the biggest contributor for both work and study migration.
Approximate trend:
2019: around 72,000
2023: around 250,000 in long-term immigration estimates.
2. Nigeria – one of the fastest-growing groups
Nigeria has seen a very large increase.
Main reasons:
Students.
Health and care workers.
Skilled workers.
Family migration.
Nigeria became one of the top sources of migrants after 2020, with numbers rising sharply.
3. China
China has remained a major source, particularly through:
International students.
Researchers.
Skilled workers.
Unlike India and Nigeria, Chinese migration has historically been more heavily linked to education. The ONS notes that study was particularly important among Chinese arrivals.
4. Pakistan
Pakistan has long been one of the UK's largest migrant communities.
Main reasons:
Family connections.
Work.
Study.
Healthcare recruitment.
Pakistan remains consistently among the top five non-EU nationalities.
5. Hong Kong
A major increase followed the introduction of the British National (Overseas) visa route after political changes in Hong Kong.
Thousands of Hong Kong residents have moved to the UK under this scheme.
6. Ukraine
Ukraine became a major source after Russia's invasion in 2022.
The UK introduced:
Homes for Ukraine.
Ukraine Family Scheme.
This was a humanitarian migration rather than normal work or study migration.
7. Romania and 🇵🇱 Poland (EU migration)
Before Brexit, Poland and Romania were among the biggest sources of immigration.
However, the pattern changed:
Poland
Large arrivals after EU expansion in 2004.
Many have since settled permanently.
Some have returned to Poland.
Romania
Became one of the largest EU sources before Brexit.
Numbers have reduced compared with the peak period.
The EU share of new arrivals has fallen significantly since free movement ended. In 2024, non-EU nationals accounted for around 81% of long-term immigration, while EU+ nationals accounted for around 13%.
Top countries of origin in recent years (approximate ranking)
🇮🇳 India
🇳🇬 Nigeria
🇨🇳 China
🇵🇰 Pakistan
🇿🇼 Zimbabwe
🇬🇭 Ghana
🇧🇩 Bangladesh
🇺🇦 Ukraine
🇭🇰 Hong Kong
🇷🇴 Romania
(The ranking changes year by year depending on whether measuring nationality, country of birth, visas issued or people arriving.)
How this affects housing and services
The countries of origin matter because different migration routes create different pressures.
Students
Large numbers from:
India
China
Nigeria
Pakistan
create pressure mainly on:
University accommodation.
Private rented housing.
City-centre flats.
This has been particularly noticeable in cities such as:
London.
Manchester.
Birmingham.
Glasgow.
Edinburgh.
Workers
Migration has helped fill shortages in:
NHS.
Care homes.
Hospitality.
Construction.
Agriculture.
However, workers also require:
Housing.
Schools for children.
GP access.
Transport.
Humanitarian arrivals
Groups arriving through refugee schemes often need:
Temporary accommodation.
English language support.
School places.
Healthcare access.
The bigger demographic change
The most significant change is not simply the number of people arriving — it is the speed of change.
Ten years ago, migration was strongly associated with:
Poland.
Eastern Europe.
EU free movement.
Today it is much more associated with:
India.
Nigeria.
China.
Pakistan.
Humanitarian routes.
This means the UK has experienced a very rapid change in the composition of its population.
