Islington and Hackney’s population sizes have both increased by just over 35 per cent since 2001, new figures suggest.

Some 23 areas of the UK have seen their population increase by more than a quarter since 2001 and some of the biggest jumps have been in London.

Tower Hamlets saw the greatest increase at 61.5pc, followed by Newham (41.6pc), Hackney (35.6pc), and Corby in Northamptonshire holding joint fourth at 35.2pc along with Islington.

The 23 areas with increases above 25pc are all in England.

However, there were 18 authority areas in the UK which saw a decrease.
