The
New York Times posted this terrific
interactive graphic on how Americans spend their day. Click on the different categories to explore groups within the population. I think the "computer use" category is probably understated, in that a lot of it is within other categories (like "work") or more and more simultaneous with others (like "TV" or "socializing"). Of course, there are those who also insist on texting while driving. I don't know how that is accounted for, but
I wish they would stop.
