An Interesting Site for GDP per Capita

Last of all, here's an interesting site (HT to the Carpe Diem blog)that provides easy comparison of GDP per capita and groups countries in various ways (economically, geographically, even religiously). I wouldn't go so far as to use it to make sweeping generalizations. Particularly because it only provides a snapshot. But it would make a very good jumping-off point to discuss institutional constraints, resource curse, and a number of other topics that lend themselves to analysis.

I hope you find it interesting.  Feel free to suggest some uses.
