geopolitical dominatrix

I have to make fun of the site name, it reminds me of marketing gimmicks like ThighMaster and MixMaster. But when it comes to world stats they are "Masters of their domain."
NationMaster.com, a massive central data source and a handy way to graphically compare nations. You can generate maps and graphs with ease on all kinds of statistics. What's more, you can select exactly which countries you want to include.
They currently have 4,050 stats, and this number is increasing all the time. They want to be the web's one-stop resource for country statistics on anything and everything, whether it be soldiers, olympic medals, tourists, English speakers or wall plug voltages. You can also view profiles of individual countries including their maps and flags. You can use correlation reports and scatterplots to find relationships between variables. Integrated into these is a full encyclopedia with over 200,000 articles.
