In sum, countries marked by high rates of organic atheism are among the most societally healthy on earth, while societies characterized by non-existent rates of organic atheism are among the most destitute. Nations marked by high degrees of organic atheism tend to have among the lowest homicide rates, infant mortality rates, poverty rates, and illiteracy rates, and among the highest levels of wealth, life expectancy, educational attainment, and gender equality in the world. The only indicator of societal health mentioned above in which religious countries fared better than irreligious countries was suicide

Of course, it is essential to clearly state that I am in no way arguing that high levels of organic atheism cause societal health or that low levels of organic atheism cause societal ills such as poverty or illiteracy. If anything, the opposite argument should be made: societal health causes widespread atheism, and societal insecurity causes widespread belief in God . . . .
