17 per cent of homes in the UK are not connected to the Internet, new ONS data has revealed.
Meanwhile, almost three quarters of adults in the UK access the Internet everyday, a 20 million increase since 2006, when comparable records began.
A sizeable chunk of the adult population - 7.1 million representing 14 per cent - are yet use the Internet however.
According to the research, the most active age group online is the 25-34 bracket, whilst the elderly are most likely to have not used the Internet - just 34 per cent of adults aged 75 years and over have ever been online.
"Internet use is linked to various socio-economic and demographic characteristics, such as age, sex, disability, geographical location and weekly earnings. For example, those who are less likely to have used the Internet include elderly and disabled adults," says the ONS.
Internet uses which continue to increase in the UK include social media, shopping, reading news online and banking.
Over half of the population have now used the Internet for reading newspapers or magazines, something which the ONS notes is of interest due to "reports of decreased physical newspaper readership".
Another industry that the Internet is having a big impact on is retail: "In 2013, as regular stories appear in the media reporting the decline of the high street, it is interesting to note that almost three quarters of all adults reported buying goods or services online," says the ONS.
Around half of the population now use social networking and online banking. Fibre optic connectivity is also on the rise, with 42 per cent of households now using the superfast service, up from 30 per cent in 2012.
