Great answer Lchoy, out of thanks
I know as of 2009, 32% was the rate for Canada for infants, which is part of a steady decline.
I've seen numbers for EU as low as 5%, while the US, Africa and middle east have high numbers, USA way above every other western nation.
Which is why I'm a bit bothered by the US rates, considering these are not because of religious reasons, simply for aesthetics, which we would never do to a girls genitals, but yet we do it for boys.
