The ONS conducts annual and quarterly internet access surveys. The annual survey provides data on household internet access and individual usage, while the larger quarterly survey allows for more detailed breakdowns by demographics. Key findings from recent surveys include over 45% of internet users accessing the internet on mobile phones in 2011, and 16% of UK adults having never used the internet as of 2012 Q1. The surveys measure internet use trends over time by age, disability, income and other factors. Summary data and publications are available on the ONS website.
