The number of people in the UK who are using the internet every day has doubled over the last six years to 33 million, according to figures from the Office for National Statistics (ONS).
During the same period, the proportion of people who have said they have never used the internet fell from 36 per cent to 16 per cent in 2012.
The most popular online activity is accessing email, carried out by 73 per cent of people, followed by retail (67 per cent) and social media (48 per cent).
However, 87 per cent of 16 to 24-year-olds are logging on to social networks such as Twitter and Facebook, nearly 40 percentage points higher than the population as a whole.
The number of people using their mobile devices to access the internet is also growing, with 50 per cent of adults going online via their phone in 2012 and 32 per cent doing so every day.
Telephone and video calling services such as Skype are also growing in popularity, with 32 per cent of adults using this form of communication, up from 16 per cent in 2009.
