A list of lists

I was doing a random walk from a link that was referred to me identifying the countries in the world with the greatest number of computers per capita, when I  found that the source has a nice little pop down menu to choose other bits of comparative data. 

I'm thinking that lists like this would be interesting for students to review and to perhaps speculate on why the order is the way it is. For example, has the North American (well Canadian) move towards banning smoking in public places led to the fact that Canada and the US do not appear in the top 25. And what about health care? We hear a lot about the amount spent here in Canada... look which country is number one on the list.
