So the more industrialized (or post-industrial) people are, the less active they are. No surprise there.
Furthermore, women in all types of societies tend, on the whole, to be somewhat more active than men. Again, one could probably have guessed that.
But there are a few exceptions when it comes to sex (or "gender" as the Economist calls it). By the looks Brazilian women are less active than Brazilian men. Maybe with that nice climate they're all lying on the beach. :-)
