Useful country information database

If you need a database of useful information on different countries in the world, e.g. country name, population, capital city, area, country code, timezone, etc, you can download from http://download.geonames.org/export/dump.

Each country's information is provided as a text file compressed into ZIP format. The text file is tab-separated and can be easily converted into some spreadsheet or database format such as Excel, Access or SQL.
