I live in Texas. I've seen it all over here and pretty much every other state I've visited in the last few years. Maybe it's an American thing?

You see it all around Europe as well. I live in a touristy area and Germans, English, French and Spanish are guilty of this as well.

Right now I'm working from a restaurant and would say 1/4 of the people are looking at a phone (give or take, didn't count!)

I'd venture to guess you'd see it wherever data is cheap.
