Not surprisingly, it’s all the 18 to 24-year-olds.
A new report from Pew Research Center has found that sexting among American adults is up since 2012, while it is also on rapid rise among youngsters and smartphone users, mainly with the growth of the internet, cell phones, and social media.
According to the report, smartphone users aged between 18 and 24 have turned out to be most likely to receive, send, and forward sexts, outpacing mobile users in their late 20s and 30s.
The report noted: "Technology in relationships is not just limited to coordination and logistics, it now encompasses even the more intimate moments.
"Sexting, or sending sexually suggestive nude or nearly nude photos and videos via cell phone, is practised by couples and singles alike," the report added.
The survey found that 9% of US adult mobile users have a self-sext to someone else, with 20 of them receiving a nude or nearly-nude images of someone else within their contact and about 3% of them forwarding a sext to someone else, which remained unaffected since 2012.
In addition, married and partnered adults have sent sexts, with single adults more likely to report receiving and forwarding such content.
The rise in sexting also correlates with the growing popularity of smartphones, which make it easy to take and share pictures and videos.
"Some 56% of American adults own a smartphone (including 80% of those 18-29), up from 46% in 2012," researchers added.
"Smartphone owners are significantly more likely than other cell phone owners to sext. Some 27% have received a sext, more than double the 10% of other cell owners who have received one.
"Smartphone owners are also more likely to send sexts – 12% vs. just 4% of non-smartphone cell owners. Forwarding sexts is also somewhat more popular among smartphone owners (4%) than other cell owners (1%)."
A quarter of married or partnered adults have sexted their partner when they were together.
