New data from the Pew Research Center doesn’t disprove these claims, but it does challenge them. ...
There are at least two different ways to think about the relationship between education and religiosity: how schooling affects belief, and how it affects practice. Pew’s researchers looked at data from a number of recent surveys, including their 35,000-person study of American religion from 2014. They found that educated people are generally less likely to believe in God: Among all U.S. adults, only 83 percent of college grads said they think God exists, while 92 percent of people with only a high-school degree or less said the same.
Within Christianity, though, the difference all but disappears. Among educated mainline Protestants, 96 percent said they believe in God, compared to 97 percent among the less educated; among Catholics, 98 percent of both groups said the same. Among Mormons, black Protestants, and evangelical Protestants, there was effectively no difference at all, because virtually everyone in those groups said they believe in God.
Educational differences had a much bigger effect on religious practice. Sixty-eight percent of college-educated evangelical Protestants go to church every week, compared to 55 percent of those who only went to high school. In fact, college grads show up in the church pews more often in nearly every kind of Christian tradition: Among mainline Protestants, weekly attendance was 36 to 31 percent, more educated to less; among black Protestants, 59 to 52 percent; and among Catholics, 45 to 39 percent. The effect was perhaps greatest among Mormons: 85 percent of Mormon college graduates go to church at least once a week, compared to 66 percent of their peers with a high-school education or less.
