This data present the average daytime population on a weekday during term-time. The dataset is available on the datastore.

The population of London swells to over 10 million people on an average day. Around 2 million people, or around a fifth, are in just three local authorities – Westminster, City of London and Camden. Nearly half of London’s daytime population comes from people in work while nearly a quarter comes from adults not in work – many of whom are retired. Tourists and visitors make up over 10 per cent of the daytime population, but it’s worth remembering this is an average across the year and the number of tourists will be higher in the summer months compared with the rest of the year.
