THE PRIVILEGE OF NOT BELIEVING

There are a few theories about why people become atheists in large numbers. Some demographers attribute it to financial security, which would explain why European countries with a stronger social safety net are more secular than the United States, where poverty is more common and a medical emergency can bankrupt even the insured.

Atheism is also tied to education, measured by academic achievement (atheists in many places tend to have college degrees) or general knowledge of the panoply of beliefs around the world (hence theories that Internet access spurs atheism).

There’s some evidence that official state religions drive people away from faith entirely, which could help explain why the U.S. is more religious than most Western nations that technically have a state religion, even if it is rarely observed. The U.S. is also home to a number of homegrown churches—Scientology, Mormonism—that might scoop up those who are disenchanted with older faiths.

The social factors that promote atheism—financial security and education—have long been harder to attain for women and people of color in the United States.

Around the world, the Pew Research Center finds that women tend to be more likely to affiliate with a religion and more likely to pray and find religion important in their lives. That changes when women have more opportunities. “Women who are in the labor force are more like men in religiosity. Women out of the labor force tend to be more religious,” says Conrad Hackett with Pew. “Part of that might be because they’re part of a religious group that enforces the power of women being at home."

In a Washington Post op-ed about the racial divides among atheists, Black Skeptics Group founder Sikivu Hutchinson points out that “the number of black and Latino youth with access to quality science and math education is still abysmally low.” That means they have fewer economic opportunities and less exposure to a worldview that does not require the presence of God.
