Yes, you can get those information from numerous websites but NationMaster allows you to use these statistics to compare the different countries. So for example, you are thinking of robbing someone, you can easily find out which country is the richest for you to rob. They bring about information and data from CIA World Fact Book, UN resources as well as OECD. You can even generate charts and maps for better comparison.
