Hands down my favorite web site is Nationmaster.com. The web site is arguably the largest and most comprehensive collection of economic and demographic information about all the countries in the world. You combine that with their charting and graphing functions and only the Legendary Redheaded, Lingerie Wearing, Video Game Playing Babe Economist Who Likes to Serve Irishmen Martini's that the Elder Economist of Yore spoke of could detract me for a Saturday evening.
All that being said, unfortunately the damn site copy rights all their charts, no matter how magnificent they may be. Alas, I can't use them here and share their splendor and glory with all of you.
But I did happen upon Index Mundi, which essentially is the same thing as Nationmaster, but;
1. It doesn't copyright the charts, thereby allowing for the advancement of economic knowledge
2. It also DOESN'T provide the correlation coefficients and other statistical measures that Nationmaster does. Thus me and Liberal Guy, and Derek cannot debate whether they are statistically significant or not.
3. It has merely a fraction of variables that Nationmaster has.
Regardless, it does make for some pretty cool charts like Fertility Rates versus GDP per capita;
Which proves children are evil.
Or Fertility Rates versus Literacy Rates
Which proves children bring about stupidity.
Regardless, now you too can be cool like real life economists and toy around with the charting function yourself come some Saturday evening when you can't find a date.
