Time Magazine has an interactive representation of some statistics about Americans on their web site. How much do we drink? How much free time do we have? How happy are we on the job? How much time do we spend commuting? These are some of the stats they show. I particularly like the ”City Population Shift” tab on the Commute map. It shows you how people shift in and out of major cities during the day/night cycles.
Also, as an interesting aside, I managed to find a draft version of this piece. It looks like Time forgot to remove it. Check out the broken version here.
