Last updated: January 2026
Next estimated update: December 2026
What’s this indicator?
This indicator shows the proportion of children in year 6 (aged 10-11) that are considered obese in each London borough.
Where is child obesity most prevalent?
Childhood obesity is more prevalent in London than England overall. In 2024/25, some 23.2% of children in Year 6 were considered obese in London, compared to 22.2% in England.
The majority of London boroughs had a higher prevalence of childhood obesity than England overall in both 2014/15 and 2024/25.
Public Health England’s latest figures in 2024/25 show that Southwark has the highest proportion of childhood obesity out of all London boroughs at 29.7%. Outside of Southwark, boroughs with higher levels of childhood obesity are mostly in the East of the City - Tower Hamlets, Barking and Dagenham and Newham all have high rates.
At the other end of the scale, the lowest levels of childhood obesity are found in wealthier boroughs in South West London: 12.1% of Year 6 children in Richmond upon Thames are obese in 2024/25, and 14.6% in Kingston upon Thames.
This means that childhood obesity is more than twice as prevalent in Southwark than it is in Richmond, just a few miles away.
Rising childhood obesity
Child obesity levels have increased over the last decade - though significantly less in London (an increase of 0.6 percentage points) than in the rest of England (3.1 percentage points).
The majority of London boroughs saw child obesity increase in this time. The boroughs that have seen the largest rise in childhood obesity are both in outer East London: Havering and Barking and Dagenham.
11 boroughs saw rates decline. Hammersmith and Fulham experienced the greatest decline in childhood obesity with a 6.0 percentage point decrease within the decade, from 23.2% to 17.3%.
