Pew Research Center:
Young adults are the most avid texters by a wide margin. Cell owners between the ages of 18 and 24 exchange an average of 109.5 messages on a normal day—that works out to more than 3,200 texts per month—and the typical or median cell owner in this age group sends or receives 50 messages per day (or 1500 messages per month).
I’m not surprised at all. With an 18 year old daughter and 16 year old son at home, I see how much texting goes on. They would both rather text their friends than talk on the phone.
Me, I like speaking to people.
