‘Food Deserts’ Mapped Across London Using Grocery Shopping Data
Analysis of 420 million Tesco grocery items from 1.6 million shoppers reveals specific London areas with limited access to nutritious food, highlighting health risks linked to poor diet.
- On November 6, Tayla Broadbridge and colleagues published a PLOS Complex Systems study mapping London's food deserts, revealing large clusters in East London and parts of west London such as Ealing and Brent.
- To target local interventions, the researchers analyzed Tesco Grocery 1.0 dataset of 420 million food items bought by 1.6 million Tesco Clubcard owners at 411 Tesco grocery stores across London in 2015 using a statistical model.
- Researchers report geographic clusters where shopping favors processed foods; inner north-west boroughs show the most nutritious trends, while east London and western boroughs have the least, with demographic links varying regionally.
- The authors argue purchase-based mapping can guide area-specific public-health interventions, as their statistical model explained much of London's variation in food buying and highlights areas most at risk of obesity, diabetes, and heart disease.
- Because transactions were linked to anonymized home areas, researchers say purchase maps reveal real access to healthy food, showing higher income relates to nutrient-deficient purchases in parts of east and west London but more nutritious ones in the inner-west.

Eating plenty of fruit and vegetables is key to staying healthy and avoiding diseases such as heart disease and stroke. But it’s often easier said than done. Places where many people eat poorly are often called “food deserts”, and their existence has typically been blamed on a lack of nearby supermarkets or grocery stores. However, my colleagues and I have discovered food deserts exist in the heart of one of Europe’s biggest and most cosmopolita…
Shopping data reveals ‘food desert’ hotspots in London, suggesting where nutritional needs are not be being met
New research has used purchasing data to map areas of London where residents may be suffering from a nutritionally inadequate diet, pinpointing where there are ‘food deserts.’ Researchers from the University of Nottingham and Adelaide analysed Tesco food purchasing records from 1.6 million people across London to understand how food purchase patterns vary and what they reveal about health. Their results, published today in PLOS Complex Systems, …
New Study Uncovers Unexpected Urban Food Deserts Through Shopping Data
A groundbreaking new study from the University of Adelaide challenges conventional wisdom surrounding the identification of food deserts by leveraging detailed grocery store purchase data rather than relying solely on physical access to stores. This innovative approach reveals that factors such as financial hardship and social inequality, rather than mere proximity to food retailers, drive nutritional deficiencies in urban populations. By focusi…
