People, people, can't we all just get along?!
Tu154lover, wikipedia is great for light reading but specific figures and facts tend to be disputed and sometimes (!) innaccurate. For any stated 'fact' or statistic there should be a reference in the form of a small number in superscript at the end of the sentence. It's always good to follow this link to see where the information came from.
This, much like Wikipedia, is not a definitive or perfectly accurate reference but may have more reliable figures and other interesting info:
