Here are a couple of additional sites to update my previous post on finding data and statistics on the open web.

Knoema draws socioeconomic data from a large number of government, non-profit, academic, and corporate sources — 500 sources, in fact. The sheer size of this site makes it an incredible source of information, from common to obscure. Data can be found by country, topic, or source, and it can be visualized and exported. You can also create a personalized profile to save and share your visualizations. For more information about the company and the site, take a look at this Guardian Datablog post.

Index Mundi is similar to Knoema, though smaller in the number of sources and databases it draws on. It presents country profiles and statistics in user-friendly formats like maps, charts, and tables and browsable categories.
