More Britons than ever have access to the internet, but inequalities remain between those with high and low incomes, official figures show.
Of those, 96% of the highest 10% of earners were online, compared to little more than one-quarter of the lowest 10%.
An increasing proportion of people - almost 40% - said they simply do not need the internet at home, while some 22% complained that a lack of skills hampered their efforts.
Concerns remain over the vulnerability of young children and teenagers to sexually inappropriate content or behaviour online, with 59% described as "very worried" or "rather worried" about their children's online activities.
Children's growing early adoption of new technology is also evident.
