But I don't think that applies here, because we are not questioning the conclusions from the statistics, only the accuracy of the gathering. Its a completely different thing to say, for example, that population growth is due to too many babies when it might be immigration or a reduction in the death rate, than it is to say that the numbers gathered are simply wrong. The truth is that you guys can't be bothered unless the numbers are so far off that its an embarrasment. Until someone who cares about it (and knows how to do it) puts their nose to the grindstone and makes sure that everything is being done correctly, they'll be largely useless.
