Whatever then, 2.04%...<quoted text>
Um, why did you make up a number. It's 2.04% that openly admit to being atheists. But the "non-religious" count as well, because without a religious belief you lack a belief in a god, therefore you're an atheist as well. The "atheist" label in that survey was likely for the atheist religions, there are a few religious that have no gods in them. So the total actually nears 14%.
But then, it doesn't matter, the majority are wrong more often than correct, and an appeal to popularity is a fallacy.
But you can't say that 14% are atheists because 13% of them say they are non-religious or agnostic, not atheists.
You don't get to change the stats to suit your argument.
