UK Population Projections Show Deaths Outnumber Births From 2026, Growth Slows
4/29/2026, 5:03:45 AM
Revised Outlook
ONS new medium-term projections show deaths will exceed births each year from 2026. Population is forecast to reach about 71 million by 2034, peak near 72.5 million in the mid-2050s, then decline.
Key Drivers
Net migration is expected to add only 2.2 million people 2024-2034 after falling to 204 000 in the year to June 2025 (-69 %). Lower fertility creates a natural change of roughly 450 000 more deaths than births.
Regional Peaks
ONS projects England to peak at 62.1 million in 2056, Wales at 3.2 million in 2035, Scotland at 5.6 million in 2033 and Northern Ireland at 1.9 million in 2031. NRS now expects Scotland to fall after 2033, and Nisra foresees a decline in Northern Ireland from 2031.
Age-Structure Shift
Pension-age adults will rise from 12.4 million (2024) to 14.2 million (2034), about 20 % of the total. Under-16s will fall from 12.6 million (18.2 %) to 11 million (15.5 %). By 2054 pensioners will be 22 % of the population, children 14.5 %.
Official Responses
James Robards (ONS) said the outlook reflects lower migration and fertility assumptions. A Home Office spokesperson announced sweeping immigration reforms. Dr Madeleine Sumption (Oxford Migration Observatory) called the post-Brexit surge a “blip”. Andrew White (NRS) linked the forecast to falling migration, and Nisra warned immigration will settle at a lower level.
Criticism & Opposition
Maike Currie (PensionBee) warned the “demographic dividend is turning into a deepening demographic drag”. SNP minister Mairi McAllan said “too few” migrants are arriving and that migration is “good and necessary”. Reform’s Thomas Kerr said immigration has pushed the system to a breaking point. Other parties stress immigration’s role for the labour market, while a House of Lords report flags young people as hardest hit by ageing.

Conflicting Reports & Gaps
All sources agree deaths will outnumber births from 2026, but differ on regional peak timing—ONS sees a UK-wide peak in the mid-2050s, while NRS and Nisra project earlier national declines. Projections omit policy changes, creating uncertainty about immigration reforms and pension adjustments.
What’s Next
The Home Office will roll out immigration reforms within a year. The House of Lords will issue a follow-up inquiry on ageing impacts. Policymakers are expected to review pension contributions and retirement age as pensioners near 22 % of the population by 2054.
