Nationmaster

Have some fun playing around with NationMaster, "a cool site developed by Luke Metcalfe, an Australian and stat-geek who was frustrated at his inability to mine the data within the CIA World Factbook. NationMaster now includes data from the World Bank, various United Nations entities, OECD (Organisation for Economic Co-operation and Development), World Trade Organization, and so on.

Here's how it works. Head over to NationMaster.com, and select a category from the pull-down menu -- anything from Crime to Industry to Sports. Once you have chosen a category, a subject-specific subcategory menu appears, from which you pick a specific topic. For example, subcategories for Health include percentage of infants immunized against measles, number of acute care beds." From there, you're on our own. I see this working for business, homeland security, and health sciences at the very least.
