Gender
As in the population overall, African-American men are significantly more likely than women to be unaffiliated with any religion (16% vs. 9%). African-American women are somewhat more likely than African-American men to describe themselves as Protestant (82% of women vs. 72% of men). Among African-American women, 62% are members of historically black Protestant churches, 16% are affiliated with evangelical churches and 4% are mainline Protestant; among men, 55% are members of historically black churches, 14% are evangelical and 4% are mainline Protestant.
African-American women also stand out for their high level of religious commitment. More than eight-in-ten black women (84%) say religion is very important to them, and roughly six-in-ten (59%) say they attend religious services at least once a week. No group of men or women from any other racial or ethnic background exhibits comparably high levels of religious observance.
Age
African-Americans are more likely to be affiliated with a faith compared with the public overall, but as with the general population, younger African-Americans are more likely than their older counterparts to report being unaffiliated with a religion. For example, nearly one-in-five African-Americans under age 30 (19%) are unaffiliated, compared with just 7% of African-Americans who are age 65 and older.
