Please excuse my sometimes terrible english. I am a native German and know about my lacks ;-) If you come across some wrong terms or grammar (and I'm sure you will), just feel free to send me an email.
The database contains several hundred thousand individual data. Unfortunately it is neither possible nor would such a project still be fun, if for each number a source indication and the stand should be looked up, saved and displayed again. Essential data such as economic data or population figures of countries are updated several times a year.
Definition of "Country"
The definition of the word "country" is often ambiguous. Both, here and elsewhere. A country has not to be a sovereign state, but can also be a dependency of another state like Greenland or Guam. What we consider as a "country" can be found here: What is a country? (German language only)
Not all, but at least some data can be downloaded as CSV files. See our download area.
