Fifteen percent of US teenagers aged 12 to 17 who own mobile phones have received nude or nearly nude images of someone they know, according to a survey released on Tuesday.
Only four percent of mobile phone-owning teens in that age group have sent sexually suggestive pictures of themselves, a practice known as "sexting," according to the Pew Research Center?s Internet & American Life Project.
The Pew survey found that girls and boys were equally as likely to have sent a suggestive picture to another person and older teenagers were more likely to have engaged in "sexting."
Eight percent of 17-year-olds with mobile phones have sent a sexually provocative image by text and 30 percent have received a nude or nearly nude image on their phone.
Only four percent of 12-year-olds have sent suggestive images of themselves.
Amanda Lenhart, a senior research specialist at Pew and the author of the report, said sexually suggestive images have become a form of "relationship currency" for teens.
"These images are shared as a part of or instead of sexual activity, or as a way of starting or maintaining a relationship with a significant other," she said. "And they are also passed along to friends for their entertainment value, as a joke or for fun."
"The desire for risk-taking and sexual exploration during the teenage years combined with a constant connection via mobile devices creates a 'perfect storm' for sexting," said Lenhart.
