Grandma and Grandpa seem to be more than compensating for lost teens.

A couple other #s surprised me:

- NY's 100+% growth. I would have thought NYC would be an early adopter. Why so different than Chicago? Chicago's 2011 # seems very close to NYC, so perhaps Chicago was an earlier adopter? Same with LA.

- The dropoff in College is interesting too, but not amongst alums. It's almost like Facebook is more useful to people who are more scattered from their old friends.

I think you've got it. In high school, I saw my friends in person every single day.

being more useful to people who aren't near their friends could explain constant growth in NYC too - don't people consistently move to there after college?

Yes - but it looks like a lower base. The initial # is very closer to Chicago. Almost like NYers were too cool for it for a while, but not now?
