London has the best levels of good health among its population, according to the census - at 84%, compared with 81% nationally.
The city also has relatively few people whose daily activities are limited because of disabilities or health problems - with the London borough of Wandsworth bottom of the list for all local authorities.
The census appeared to confirm a boom in cycling in London, with 161,700, or 2.6% of the population, using this form of transport to get to work in the capital.
