Net migration could fuel a rise in the UK population to 72.5 million by 2032, figures suggest.
The Office for National Statistics (ONS) has projected a population growth of 7.3% between 2022 and 2032, compared with an increase of 6.1% over the previous 10 years.
The number is almost entirelybased on the net migration – the difference between those entering and leaving the country – of an estimated 4.9 million people over the 10-year period.
Downing Street said it wanted to bring down the “staggeringly high” levels of migration, but ruled out an “arbitrary” cap.
The number of births and deaths is expected to be roughly equal, while it is projected there will be an additional 1.7 million pensioners by 2032.
Between mid-2022 and mid-2032, the ONS projections suggest:
- 6.79million people will be born
- 6.81million people will die
- 9.91million people will immigrate long-term to the UK
- 4.98million people will emigrate long-term from the UK
Downing Street said the government will set out a “comprehensive plan” to end high migration numbers.
The prime minister’s official spokesman said Sir Keir Starmer “doesn’t think that setting an arbitrary cap, as previous governments have done, is the best way forward in terms of significantly reducing migration.”
Shadow home secretary Chris Philp said the number immigrating long-term to the UK was “shocking and unacceptable”, and must be “stopped from materialising.”
“Ten million arrivals over 10 years is far too high”, he said, adding: “We need a binding legal cap on visas issued each year which is very, very substantially lower than this in order to get the numbers down and under control.”
A Home Office spokesperson said the government will soon “set out a comprehensive plan to restore order to our broken immigration system”.
“We will link our immigration, skills and visa systems so we can grow our domestic workforce, end the reliance on overseas labour and boost economic growth.”
The ONS’s long-term net migration projections have increased in comparison to last year’s figures.
Statisticians had previously assumed that, from 2028, net migration would contribute 315,000 extra people to the UK per year – this has now been revised to 340,000.
The ONS stressed the figures are projections – not predictions or forecasts – and warned that real numbers could be higher or lower than suggested.
England is expected to see the biggest population increase among the UK nations, with a projected rise of 7.8% compared with 5.9% for Wales, 4.4% for Scotland and 2.1% for Northern Ireland.
The natural change in population – number of births and deaths – is projected to be “around zero”.
This is because deaths are projected to rise due to a large number of people born in the post-World War Two period reaching older ages, the ONS says.
The projections also highlight an increasingly ageing population, and suggests there could be fewer children due to lower fertility rates.
By the middle of 2029, the number of deaths is projected to overtake births, meaning net migration will be the only source of population growth.
This suggests that if there were no immigration or a huge increase in babies being born, the population would be shrinking.
Economic growth would almost inevitably slow and there would be real questions about who would care for increasing numbers of elderly people.
The statistics are used in planning including fiscal projections and across public services such as education, health, and pensions.
If incorporated by the Office for Budget Responsibility (OBR), the new projections should improve “economic and fiscal outlook, and reduce borrowing by around £5 billion”, according to the Resolution Foundation.
