The population of London on census day (27 March 2011) was 8.2 million, an increase of 12 per cent from 2001 when it was 7.3 million. The Office for National Statistics (ONS) published the first results from the 2011 Census today.
London was the greatest-growing region across England and Wales, ahead of three regions that grew by 8 per cent – South East, East of England and East Midlands.
By comparison the population across the whole of England and Wales increased by 7 per cent to 56.1 million, the largest growth in population in any 10-year period since census taking began in 1801.
Jil Matheson, National Statistician said:
"I'd like to thank everyone in London for their support. The 2011 Census has been a resounding success and I am proud of the incredible effort that has been put in. It is a rich source of information about the population and its characteristics. Across England and Wales around 19 out of 20 people responded and we have excellent statistical methods for ensuring we have a complete estimate of the whole population. These statistics will provide valuable information for planners, policy-makers and the public for years to come. "
Most local authorities in London saw their populations increase between 2001 and 2011, although there was a decrease of 2.2 per cent in Kensington and Chelsea. Across all of England and Wales 17 local authorities saw a decrease in population. The total population of England and Wales was 56.1 million, of which 53.1 million were in England.
Nine of the 20 local authorities with the fastest population growth in England and Wales were in London, and Tower Hamlets and Newham were the only authorities in England and Wales to show growth of more than 20 per cent, with the fastest growth of all being 26.4 per cent in Tower Hamlets. The largest local authority by population in London was Croydon with 363,400 people, an increase of 28,300 (8.5 per cent) between 2001 and 2011.
The smallest was the City of London, with 7,400.
The 19 most densely populated local authorities in England and Wales were in London, with Islington the most densely populated of all with 13,873 people per square kilometre, which equates to about 140 people on a rugby pitch. Bromley was the least densely populated with 2,060 people per square kilometre, which is still more than five times the average population density of England and Wales as a whole which equates to about 21 people per rugby pitch.
The local authority in London with the largest proportion of people aged 65 and over was Havering with 18 per cent; by contrast, only 6 per cent of the population in Tower Hamlets were in this age group, the lowest figure in not only London but all of England and Wales. The largest proportion of people aged 19 and under in London (and England and Wales) is in Barking and Dagenham with 31 per cent; by contrast, 11 per cent of the population of the City of London is in this age group, the smallest proportion in England and Wales.
There has been an increase of 400,000 (13 per cent) under-five-year-olds throughout England and Wales between 2001 and 2011. This was particularly pronounced in London; where there were 112,700 under-fives compared with 2001, an increase of 24 per cent. Barking and Dagenham has the highest proportion in this age group with 10 per cent, and the City of London the lowest (3 per cent).
The total number of households in London was 3.3 million. The City of London also has the smallest average household size in England and Wales, with 1.6 people. By contrast, Newham has an average household size of 3 people, the largest in England and Wales.
So London has finally broken the 8 million barrier, and it should be noted there is similar growth within London's Metro Area
