I think I need to point out, that some of the most dishonest people, are atheists posing as Christians, so they would get placed in the wrong category in your study.
This would be especially true in countries/regions where atheism is in the minority or discriminated against in some way.
Far better to qualify you claim as:
People who claim to be atheist, are more moral than people claiming to be Christian.
