While social media usage is lower amongst those of pensionable age, 55% of over-65s in Britain have an active Facebook page, while more than two-thirds regularly view videos on YouTube.
According to research conducted by social media agency Umpf, more than three-quarters (77%) of the UK's 48.6m-strong adult population has an active Facebook page, representing 37.4m people signed up to the social network. Twitter is also popular, with 15.5m Brits regularly using the microblogging site. The majority (95%) of 18 to 25-year-olds are now active users of Facebook.
The research, conducted by polling agency Your Say Pays and based on a sample of nearly 2,400 adults, revealed that location-based platforms, such as Foursquare, were used by 15% of UK adults, equating to 7.2m people. Photo-sharing platform Flickr attracts 6.7m adult users and LinkedIn has 7.9m.
Men are more likely to have an account on LinkedIn, the professional network that had a multi-billion dollar floatation on the US stock market in May, at 22% compared to just 13% of women. In contrast, Facebook was used regularly by 80% of women, but only 72% of men.
On average, the South East boasted the highest numbers of people using social media platforms, while Northern Ireland had the lowest participation. However, people in Northern Ireland were among the heaviest users of the Google-owned YouTube, at around two-thirds.
Jon Priestley of Umpf said that the research reveals how "endemic" use of social media services is in the UK, with broad adoption across all platforms and amongst all age groups.
"The social media landscape is changing rapidly and gender divides are starting to become apparent, with men clearly favouring YouTube and LinkedIn, but women opting to use Facebook as their chosen medium of communication," said Priestley.
"Our research clearly shows how geography is playing a key role in social media adoption, with distinct geographical areas beginning to favour different social media platforms to communicate with their networks."
At the Edinburgh TV Festival last month, The IT Crowd creator Graham Linehan said that Twitter has "put television back in the crowd" by creating more engagement with viewers.
