  I'm not the one who added the data but:  * I agree with your statement that it is inaccurate, among other things, because government is not aware of all the business going on. It may have an agenda tweaking some of the numbers, but this is the same for any source of such information for any country.  * I don't see any particular source I could fully trust for any given country anyway. Any other / foreign institutions know have a lot less information and they also have their own agenda, so their numbers cannot be trusted either.  * In that case there really is just one information that can be posted anyway - the official one, however inaccurate it may be.
