Number of Atheists Worldwide

ReligionFacts.com has a chart on their site, “The Big Religion Chart,” summarizing the major “religions / sects / groups / philosophies / belief systems.” Atheism is included in the chart and is listed as having 1.1 billion adherents worldwide. I’m virtually certain that this number is wildly overstated. The only way they can come up with a number that big is to include everyone who says they are “nonreligious.” The problem with that approach, of course, is that a person can be “nonreligious” and believe in God.
