The data showed that just 28.6 per cent of people over 75-years-old had used the internet, suggesting it is older people who are less likely to have gone online.
By contrast, almost all 16 to 24 year olds (99%) have used the internet.
A total of 87% of men have used the internet compared to 82% of women.
The research revealed that disabled people are three times more likely never to have used the internet than people without a disability.
