The United Kingdom faces a sustained demographic decline, with deaths projected to consistently outnumber births from 2026 onward. This trend, according to official projections, signals a long-term shift in the country’s population dynamics.
Data from the Office for National Statistics (ONS) indicates that England and Wales will experience 450,000 more deaths than births over the next decade. The number of deaths is expected to surpass the number of births this week—a development distinct from temporary spikes observed during the early pandemic in 2020 and the post-pandemic period of 2023.
The decline stems primarily from falling fertility rates. In 2022, British women had an average of 1.39 children per woman—well below the replacement level of 2.1 required to sustain population stability without significant immigration. While immigration remains high and partially offsets the trend, official estimates reveal that 40 percent of babies born last year have at least one parent born outside the United Kingdom.
Regional patterns are starkly divided. London and the West Midlands have seen increases in births due to higher immigrant populations, whereas the North East and South West of England experience population declines.
The ONS, Britain’s leading statistical authority, published these findings alongside a report from the Center for Social Justice, a social policy think tank, on Tuesday.
Edward Davies, Director of Research at the Center for Social Justice, emphasized: “We need to prioritize marriage, help young men step up to the plate, and make it easier for couples who want children to afford to have them.”
By 2034, the UK population is expected to grow by 1.7 million primarily due to immigration. However, the country will enter overall decline by the mid-2050s. Economic experts warn that declining birth rates could place significant pressure on the state pension system, potentially requiring the state pension age to rise to 75 to maintain current worker-to-pensioner ratios.
This report builds on a May analysis revealing England and Wales recorded their lowest fertility rate ever in 2025—1.39 children per woman—down from 1.41 in 2024, well below the replacement level needed for long-term population stability without mass migration.
