London, UK – November 6, 2025 – An analysis of grocery store data has revealed the existence and extent of food deserts across London, raising concerns about equitable access to nutritious food for residents in specific boroughs. The findings, published today, pinpoint areas where residents face notable barriers to obtaining affordable and healthy groceries.
The study, based on transactional records from multiple supermarket chains, demonstrates a correlation between socioeconomic factors and limited access to full-service grocery stores. Residents in identified food deserts-primarily in outer London boroughs-rely heavily on convenience stores and smaller shops wiht limited selections of fresh produce and healthy options, frequently enough at higher prices. This disparity impacts approximately one in ten Londoners, disproportionately affecting low-income families and elderly individuals. Researchers anticipate the data will inform targeted interventions aimed at improving food security and public health outcomes.
The analysis, conducted by independent researchers accessing anonymized sales data, focused on the density of grocery stores offering a wide range of fresh foods relative to population density and income levels. Areas with a low ratio of supermarkets to residents, coupled with high poverty rates, were flagged as potential food deserts. The data confirms that residents in these areas often travel significantly further-and spend more-to access comparable grocery options.
“The implications are clear: where people live directly impacts their ability to maintain a healthy diet,” stated a researcher involved in the study. ”This isn’t simply a matter of convenience; it’s a matter of health equity.”
The findings come as London’s population continues to grow and income inequality persists. Local authorities and community organizations are now evaluating the data to develop strategies, including incentivizing supermarkets to open locations in underserved areas, supporting mobile grocery initiatives, and expanding community gardens. Further research is planned to assess the long-term health consequences of limited food access.
