Half the Irish population over the age of 15 is now on the social networking site Facebook, which amounts to 1.75m users, Ipsos-MRBI figures show.
Ninety per cent of people aged 15-24 use the social media site, and two-thirds log onto Facebook every day.
Teenagers aren’t the only ones signing up on Facebook – one in five 55-64 year olds have a Facebook account.
Ipsos-MRBI also had a look at usage of microblogging site Twitter. Seven per cent of the Irish population uses Twitter, the figures show, with 30pc of Twitter users checking their accounts daily. This is an 18pc increase from six months ago.
Accounts on the business networking site LinkedIn have risen by 9pc, a 50pc hike in six months.
