At an overall level, adults in London are slightly less likely to be inactive (<30mins/week exercise) than adults across England (both around 1-in-4 inactive).
The overall level masks a huge variation in inactivity by borough in London. The highest inactivity is in Havering, B&D and Brent (all around 1-in-3 inactive). Islington, Richmond, Hackney and Camden have the lowest inactivity (only around 1-in-7).
The geography, infrastructure and demographics of these locations all play a part.
Inactivity in London is massively benefitted by the proportion of residents who engage in Active Travel (46% in London versus 34% for England overall).
The only activity where London is significantly out of step is Gardening.
