The Pew Research Center has issued their Teens and Technology 2013 report on parents and teens (ages 12-17) in the USA.

Here are the key findings:

Smartphone adoption among American teens has increased substantially and mobile access to the Internet is pervasive. One in four teens are “cell-mostly” Internet users, who say they mostly go online using their phone and not using some other device such as a desktop or laptop computer.

• 78% of teens now have a cell phone and 47% of them own smartphones. That translates into 37% of all teens who have smartphones, up from just 23% in 2011.
• 23% of teens have a tablet computer, a level comparable to the general adult population.
• 95% of teens use the Internet.
• 93% of teens have a computer or have access to one at home. 71% of teens with home computer access say the laptop or desktop they use most often is one they share with other family members.

The nature of teens’ Internet use has transformed dramatically — from stationary connections tied to shared desktops in the home to always-on connections that move with them throughout the day. In many ways, teens represent the leading edge of mobile connectivity, and the patterns of their technology use often signal future changes in the adult population.
