I guess this would be the place to put a demographics realted idea.
Remember those "If the world were a village" thingies we've all seen in high school? "200 people would be Chinese, 5 people would control 90% of the wealth" etc.
This would be a very nice way to look at demographics. I imagine some things (wealth, population" should be pretty easy to calculate.
Ona nother demographics note, it would be nice to know what they mean. Millitary Service? Did anyone ever figure that out? I was always in first place for all categories, but in last for millitary service.. hrm...
