Fascinated by facts, or looking for any type of data on countries and US states? The NationMaster and StateMaster websites should be a big help. These websites cull data from a wide range of public and private sector sources, and one can create searches of range of categories, generate charts and tables, maps, etc. NationMaster focuses on individual nations and comparisons between nations. StateMaster does the same for US states. The content may not always have the depth needed for specialized research, but I have found StateMaster, for example, far easier to use than the Census Bureau’s Data Ferret. Advertising banners can be distracting.
