Men are taking nearly double the amount of "selfies" as women and sharing them on social media, according to a survey.

More than 2,000 adults 18 to 30 about their habits of taking images of themselves on their smartfones, a phenomenon which has surged in popularity involving everyone from Hollywood celebrities to Barack Obama.

It found that on average men posted three self portraits a week compared with 1.6 for women. Over a third of men said they shared more than five a week.

When asked what prompted them to take the images made famous by the likes of Kim Kardashian, a quarter of men said they shared selfies to make an ex or a partner jealous, and one in 10 said it was to make themselves look more desirable.

Half the women said they took selfies to make others jealous, while only 7 per cent took pictures to make themselves appear more desirable.

The term "selfie" was first used in 2002. The poll was carried out by mobile phone company HTC.
