These are among the key findings of the U.S. Religious Knowledge Survey, a nationwide poll conducted from May 19 through June 6, 2010, among 3,412 Americans age 18 and older, on landlines and cell phones, in English and Spanish. Jews, Mormons and atheists/agnostics were oversampled to allow analysis of these relatively small groups.
Previous surveys by the Pew Research Center have shown that America is among the most religious of the world’s developed nations. Nearly six-in-ten U.S. adults say that religion is “very important” in their lives, and roughly four-in-ten say they attend worship services at least once a week. But the U.S. Religious Knowledge Survey shows that large numbers of Americans are uninformed about the tenets, practices, history and leading figures of major faith traditions – including their own. Many people also think the constitutional restrictions on religion in public schools are stricter than they really are.
When education and other demographic traits are held equal, whites score better than minorities on the survey’s religious knowledge questions, men score somewhat better than women, and people outside the South score better than Southerners.
