If it seems like American teens are texting all the time, it’s probably because on average they’re sending or receiving 3,339 texts a month.
No one texts more than teens (age 13-17), especially teen females, who send and receive an average of 4,050 texts per month. Teen males also outpace other male age groups, sending and receiving an average of 2,539 texts.
Texting is currently the centerpiece of mobile teen behavior. 43 percent claim it is their primary reason for getting a cellphone, which explains why QWERTY input is the first thing they look for choosing their devices.
Teens are not only using more data, but they are also downloading a wider range of applications. Software downloads among teen subscribers who use apps enjoyed a solid 12 percent increase in activity versus last year, from 26 to 38 percent.
When using websites, teenagers have a lower success rate than adults and they're also easily bored. To work for teens, websites must be simple -- but not childish -- and supply plenty of interactive features.(Jakob Nielsen's Alertbox)
