The survey concluded that “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 discernible.”
It found the US to be one of the most religious nations.
