I'm sorry, but either your reading or your counting needs work.  It is YOU who are wrong.  USA (and U.S.A.) are FAR more common than "United States of America" when input into Google.  I don't know how your numbers could differ so dramatically from mine.   404 million to 713 million, that's not even close.  As to the other points made, there is no need to change anything other than this article, as this is the only article we are currently considering for correction.  If in the future someone brings this point up for Germany or Mexico, then deal with it then.  Claiming that some type of encyclopedic accuracy would demand across the board revisions is silly on its face.
