: CS1 maint: multiple names: authors list (link)About three-quarters of U.S. atheists (77%) do not believe in God or a higher power or in a spiritual force of any kind, according to our summer 2023 survey. At the same time, 23% say they do believe in a higher power of some kind, though fewer than 1% of U.S. atheists say they believe in "God as described in the Bible." This shows that not all self-described atheists fit the literal definition of "atheist," which is "a person who does not believe in the existence of a god or any gods," according to Merriam-Webster.

(help)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).
