The Pew Research Center shares its Religious Landscape Study (RLS) and finds Christianity in the United States, which has been on a steady decline, is stabilizing. The percentage of those who identify as “religiously unaffiliated” has increased. 

Over the past 17 years, three of these studies have been conducted with findings based on more than 35,000 adults. The survey aims to offer definitive numbers on the size of religious groups in America. It is a statistical representation of all 50 states and the District of Columbia.

The RLS finds that 62% of U.S. adults surveyed identify as Christians, down nine percentage points since 2014 and 16 percentage points since 2007. Still, between 2019 and 2024, the rate of adults identifying as Christians has been relatively stable, ranging from 60% to 64% of those surveyed. The most recent survey’s results are in the middle of this range, evidence of a likely leveling off since 2019.

The largest subgroup is Protestants (40%). This is followed by 19% identifying as Catholic and 3% as “other Christians,” representing the Greek and Russian Orthodox Churches, the Church of Jesus Christ of Latter-day Saints, Jehovah’s Witnesses, and many others.

While both Protestant and Catholic numbers are considerably lower since 2007, the Protestant population remains relatively level since 2019. On the other hand, the Catholic segment has been stable since 2014.

At the same time, the study found the number of American adults who identify with a religion other than Christianity is increasing, though still relatively small (Jewish, 1.7%, Muslim, 1.2%, Buddhist, 1.1%, and Hindu, 0.9%, respectively).

Religiously unaffiliated adults, who identify either as atheists, agnostics or “nothing in particular,” make up 29% of the U.S. population. Also known as religious “nones,” this group has recently stabilized after an extended period of continual growth.

“But, despite these signs of recent stabilization and abiding spirituality, other indicators suggest we may see further declines in the American religious landscape in future years,” Pew said. “Namely, younger Americans remain far less religious than older adults.”
