Religious Identity in 2020

Nearly one in four American adults reports being religiously unaffiliated, according to PRRI's 2020 Census of American Religion. The 23 percent who say they are religiously unaffiliated is below the peak of 26 percent recorded in 2018. Nevertheless, the religiously unaffiliated group is larger than any single religious affiliation.
