  Various studies have reported positive correlations between levels of education, wealth, and IQ with atheism. According to 2024 data from Pew Research Center, atheists in the United States are more likely to be white compared to the general U.S. population (77% vs 62%). In a 2008 study, researchers found intelligence to be negatively related to religious belief in Europe and the United States. In a sample of 137 countries, the correlation between national IQ and disbelief in God was found to be 0.60. According to evolutionary psychologist Nigel Barber, atheism blossoms in places where most people feel economically secure, particularly in the social democracies of Europe, as there is less uncertainty about the future with extensive social safety nets and better health care resulting in a greater quality of life and higher life expectancy. By contrast, in underdeveloped countries, there are far fewer atheists.
  
  The relationship between atheism and IQ, while statistically significant, is not a large one, and the reason for the relationship is not well understood. One hypothesis is that the negative relationship between IQ and religiosity is mediated by individual differences in nonconformity; in many countries, religious belief is a conformist choice, and there is evidence that more intelligent people are less likely to conform. Another theory is that people of higher IQ are more likely to engage in analytical reasoning, and that disbelief in religion results from the application of higher-level analytical reasoning to the assessment of religious claims.
  
  In a 2017 study, it was shown that compared to religious individuals, atheists have higher reasoning capacities and this difference seemed to be unrelated to sociodemographic factors such as age, education and country of origin. In a 2015 study, researchers found that atheists score higher on cognitive reflection tests than theists, the authors wrote that "The fact that atheists score higher agrees with the literature showing that belief is an automatic manifestation of the mind and its default mode. Disbelieving seems to require deliberative cognitive ability." A 2016 study, in which 4 new studies were reported and a meta-analysis of all previous research on the topic was performed, found that self-identified atheists scored 18.7% higher than theists on the cognitive reflection test and there is a negative correlation between religiosity and analytical thinking. The authors note that recently "it has been argued that analytic thinkers are not actually less religious; rather, the putative association may be a result of religiosity typically being measured after analytic thinking (an order effect)," however, they state "Our results indicate that the association between analytical thinking and religious disbelief is not caused by a simple order effect. There is good evidence that atheists and agnostics are more reflective than religious believers." This "analytic atheist" effect has also been found among academic philosophers, even when controlling for about a dozen potential confounds such as education.
  
  Some studies do not detect this correlation between atheism and analytic thinking in all of the countries that they study, suggesting that the relationship between analytic thinking and atheism may depend on culture. There is also evidence that gender may be involved in what has been termed the analytic atheist effect; because men have been found more likely to endorse atheism, and men often perform slightly better on tests of analytic thinking, when not controlling for variables such as math anxiety, the correlation between atheism and analytic reasoning may be partly explained by whatever explains observed gender differences in analytic thinking.
