Because there are 6 billion people on this planet, and each one of them is individual from the rest, and affected individually by things such as religion. Taking a base sample is almost impossible, because there are hundreds of differents religions, ways of practicing those religions, and millions of different people have millions of different views on those religions.
You could theoretically gather a group of individuals and record religion or the lack of religion on their lives, but it would only prove that those individuals were affected that specific way by that specific understanding of religion.
People aren't numbers.
