Conclusion
between 500,000,000 and 750,000,000 humans currently do not believe in God. Such figures render any suggestion that theism is innate or neurologically based untenable. The nations with the highest degrees of organic atheism (atheism which is not state-enforced through totalitarian regimes but emerges naturally among free societies) include most of the nations of Europe, as well as Canada, Australia, New Zealand and Israel. There also exist high degrees of atheism in Japan, Vietnam, North Korea, and Taiwan. Many former Soviet nations, such as Estonia, Ukraine, Kazakhstan, and Belarus also contain significant levels of atheism. Atheism is virtually non-existent in much of the world,...

Conclusion
between 500,000,000 and 750,000,000 humans currently do not believe in God. Such figures render any suggestion that theism is innate or neurologically based untenable. The nations with the highest degrees of organic atheism (atheism which is not state-enforced through totalitarian regimes but emerges naturally among free societies) include most of the nations of Europe, as well as Canada, Australia, New Zealand and Israel. There also exist high degrees of atheism in Japan, Vietnam, North Korea, and Taiwan. Many former Soviet nations, such as Estonia, Ukraine, Kazakhstan, and Belarus also contain significant levels of atheism. Atheism is virtually non-existent in much of the world, however, especially among the most populated nations of Africa, South America, the Middle East, and much of Asia. High levels of organic atheism are strongly correlated with high levels of societal health, such as low homicide rates, low poverty rates, low infant mortality rates, and low illiteracy rates, as well as high levels of educational attainment, per capita income, and gender equality. Most nations characterized by high degrees of individual and societal security have the highest rates of organic atheism, and conversely, nations characterized by low degrees of individual and societal security have the lowest rates of organic atheism. In some societies, particularly Europe, atheism is growing. However, throughout much of the world – particularly nations with high birth rates – atheism is barely discernable.
