According to a new study, the percentage of non-religious Americans has grown 6.8% since 1990 while most major religious groups lost membership. Non-religious Americans now constitute an estimated 15% of the population, with Catholics and Baptists representing 25.1% and 15.8%, respectively.
The “Christian” category (which included non-denominational, unspecified Christian and Protestant, and evangelical/born-again) is estimated at 14.2%, a 0.6% decrease since 1990.
“Mainline Protestants” and Baptists accounted for the largest decreases since 1990, at 5.8% and 3.5%, respectively.
The religious groups with the largest gains? “Protestant denominations” (i.e., Churches of Christ, Jehovah’s Witnesses, and Seventh-day Adventist) and “Eastern religions,” which both saw modest 0.5% gains.
