I say Atheism is declining because while there are more Atheists than before, the percentage of those who are Atheist is smaller.   http://en.wikipedia.org/wiki/Demographics_of_atheism#Geographic_distribution

I think that statement pretty much disproves itself. If there are MORE atheists, how can atheism be in-decline? That actually shows they are increasing. They are only decreasing relative to religious populations.
