According to this Nielsen study, American teens between 13-17 years old are sending or receiving, on average, 3,339 texts per month, and teen girls send or receive 4,050 per month. (Obviously, this is among teens with cell phones.) It’s hard to believe that the average is distorted by a minority of massive users – that’s already a text every 7 to 9 minutes across the whole waking day. Of course, I could be wrong about how much they sleep. On the other hand, the study was conducted between April and June, 2010, so at least some of them were presumably in school – not that this necessarily eliminates all opportunities to text, I know, but it must cut down on them somewhat, right? I mean, we’re talking about high school, not college, here.
