London faces funding crisis as 2021 Census undercounts population by nearly 300,000

Wednesday, 24 September 2025 4:04AM UTC

A flawed 2021 Census underestimates London's true population, risking billions in public funding and threatening essential services amid post-pandemic growth and recovery.

London's looming funding crisis exposes the flawed reliance on 2021 Census data, which undercounts the city’s true population by nearly 300,000—an error driven by the undignified chaos of the pandemic era. With the census coinciding with the third national COVID-19 lockdown, many residents fled the city’s confines, skewing figures and jeopardizing vital public funding allocations.

This misrepresentation risks depriving Londoners of the resources they desperately need. Over £4 billion of government funding for local authorities hinges on these dubious census figures, threatening to slash investments in healthcare, policing, and fire services when the city is again experiencing a resurgence in population and activity. London Councils' concerns are justified: the pandemic’s unprecedented circumstances, including high numbers of students, migrant workers, and younger professionals temporarily leaving the city, mean the data cannot be trusted to reflect current realities.

What likely began as a temporary dip—estimated at around 75,000 due to migration outflows—has now reversed, with evidence pointing to London’s population surpassing previous records. Yet, the flawed 2021 data stubbornly persists, suggesting a perception of shrinking needs that are, in fact, only increasing. The discrepancy exposes the failure of the government’s outdated funding formulas, which are predicated on a census that no longer corresponds with the post-pandemic landscape.

This situation demands urgent correction. Left unaddressed, the misallocation of funds will only deepen London's infrastructure and service deficits, undermining the quality of life for residents and eroding confidence in our public institutions. The new government’s complacent acceptance of these flawed figures reveals a concerning lack of oversight and understanding of London’s true needs.

In truth, the official 8.8 million figure grossly underestimates the city’s current population. Policymakers must recognize the critical necessity of reassessing and updating these statistics to reflect the real circumstances. Only through decisive action can we ensure London receives the fair funding it rightly deserves—funding that aligns with its actual demands and supports a thriving, resilient city.
