Secular/Nonreligious/Agnostic/Atheist: This is a highly disparate group and not a single religion. Although atheists are a small subset of this grouping, this category is not synonymous with atheism. People who specify atheism as their religious preference actually make up less than one-half of one percent of the population in many countries where much large numbers claim no religious preference...In most countries only a tiny number of people (zero to a fraction of 1 percent) will answer "atheism" or "atheist" when asked an open-ended question about what their religious preference... A slightly larger number answer "no" when asked simply if they "believe in God" (omitting wording indicating more nebulous, less anthropomorphic conceptions of divinity)...Estimates for atheism alone (as a primary religious preference) range from 200 to 240 million. But these come primarily from China and former Soviet Union nations (especially Russia).
Between 500 million and 750 million humans currently do not believe in God.
