The New York Times has an article that highlights the percentage of college graduates that each US religion has, and the percentage of members of each religion who have a household income greater than $75,000.
The least educated or affluent? Pentecostals, Jehovah's Witnesses and Baptists.
The most educated or affluent? Hindus, Reform Jews, Conservative Jews, Anglicans/Episcopalians.
The most average? Mormons, Lutherans and Catholics.
From the article:
The most affluent of the major religions — including secularism — is Reform Judaism. Sixty-seven percent of Reform Jewish households made more than $75,000 a year at the time the Pew Forum on Religion and Public Life collected the data, compared with only 31 percent of the population as a whole. Hindus were second, at 65 percent, and Conservative Jews were third, at 57 percent.
On the other end are Pentecostals, Jehovah’s Witnesses and Baptists. In each case, 20 percent or fewer of followers made at least $75,000. Remarkably, the share of Baptist households making $40,000 or less is roughly the same as the share of Reform Jews making $100,000 or more. Overall, Protestants, who together are the country’s largest religious group, are poorer than average and poorer than Catholics. That stands in contrast to the long history, made famous by Max Weber, of Protestant nations generally being richer than Catholic nations.
