Falling Birth Rates, Housing Costs and Families Moving Away
By Oliver Grant
London’s schools are facing mounting pressure as pupil numbers fall, forcing closures and mergers across the capital. Behind the trend lies a wider concern about the cost of raising a family, housing affordability and the movement of families out of London.
According to London Councils, around 90 schools have closed or merged across London over the past five years. The organisation warns that declining pupil numbers could reduce school funding by approximately £45 million over the next four years.
The figures highlight an education challenge with wider social and economic implications. However, the evidence points to several contributing factors rather than one single cause.
Falling birth rates and financial pressures
A major driver is the declining birth rate, which means fewer children are entering Reception classes. London’s high housing costs and the wider cost of living may also influence decisions about whether families can afford to remain in the capital.
For parents, suitable housing, childcare, transport and everyday expenses all affect household budgets. Some families may choose to move to areas where they can secure more space or reduce living costs.
When enrolment falls, schools can struggle to cover staffing and other fixed expenses because funding is largely allocated according to pupil numbers. This can lead to reduced subject choices, fewer extracurricular activities and, in some cases, closure.
Research shows families are moving away
A September 2025 study by the Education Policy Institute found that around 20,000 pupils from London’s 2017/18 Reception cohort were no longer recorded in London by the time they would have reached Year 6. This represented approximately 20 per cent of that cohort, compared with 17 per cent of the 2012/13 cohort.
The study also found that nearly 5.5 times as many pupils moved from London to other English regions as moved into London from those regions.
These findings indicate that falling birth rates alone do not explain the decline in London’s school population. Family relocation is also significant, although the research does not establish why every household moved.
Are British families emigrating?
International emigration is relevant to the broader debate, but the evidence must be interpreted carefully.
The Office for National Statistics estimated that 246,000 British nationals left the UK to live abroad for at least 12 months in the year ending December 2025. This was slightly below the revised estimate of 257,000 for 2024. The figures for 2025 remain provisional.
These are national figures. They do not reveal how many departing British citizens were London residents, parents of school-age children or directly connected to school closures.
Children disappearing from London’s state-school records may also have moved elsewhere in England, entered independent education or begun home education. International emigration may explain some departures, but the available evidence cannot quantify its contribution to London’s school closures.
What happens next?
School closures affect more than enrolment figures. Children may lose familiar surroundings, parents may face longer journeys, and staff can experience uncertainty about their employment.
Councils need transparent consultation processes and reliable forecasts to ensure decisions protect children’s interests. Policymakers should also consider housing affordability and improve data on why pupils leave London’s state-school system.
Reflection
London’s emptying classrooms reflect a combination of falling birth rates, family relocation and wider demographic change. High housing costs are an important part of the debate, while international emigration warrants further investigation.
The evidence does not prove that British citizens emigrating are the principal cause of school closures. It does show that London must understand why its school population is changing and how education, housing and family policy can respond.
A city’s future depends not only on its economic strength, but also on whether families can afford to build their lives there.
