- Christianity remains dominant in the U.S. Congress, with 87% identifying as Christians.
- The number of religiously unaffiliated members, or "nones," has increased to three.
- Congress' religious composition lags behind the growing number of "nones" in the U.S.
WASHINGTON — As a growing share of U.S. adults turns away from religion, Christianity still thrives in one American institution: the U.S. Congress.
Members of the 119th Congress overwhelmingly identify as religious, and though the share of Christian members of Congress has dropped slightly in recent years, Christians are still overrepresented in the Capitol.
According to data compiled by CQ Roll Call and organized by Pew Research Center, 461 members of the incoming Senate and House of Representatives — or 87% — identify as Christians.
That's down from 88% two years ago and 92% a decade ago, but it is far ahead of the 62% of U.S. adults who identify as Christian, per Pew's polling.
In one way, the incoming Congress will be record-breaking: for the first time, multiple members describe themselves as religiously unaffiliated, or "none." Kyrsten Sinema, the outgoing independent senator from Arizona, made history when she became the first U.S. congressperson to ever describe her religion as "none"; in the incoming Congress, three will do the same: Rep. Yassamin Ansari, D-Arizona; Rep. Emily Randall, D-Washington; and Rep. Abraham Hamadeh, R-Arizona.
In recent decades, the share of U.S. adults who identify as "nones" has increased dramatically. Still, the share of "nones" in Congress — making up less than 1% of the body — far trails the 28% of U.S. adults who have no religious affiliation.
That disparity between the country's religious makeup and Congress' is not surprising, said Ryan Burge, a professor of political science at Eastern Illinois University. "Congress represents America as it looked 20 or 30 years ago, not the way it looks today," Burge told CQ Roll Call.
Among congressional Democrats, the shift toward a religious makeup that more closely represents the country appears to be occurring more rapidly. A majority of Democrats — 75% — identify as Christian, and the remaining quarter includes a diverse array including Jews, Buddhists, Muslims, Hindus, Unitarian Universalists and a humanist. Meanwhile, a vast majority of Republicans — 98% — identify as Christian.
Latter-day Saints make up a shrinking share of Congress. In the 114th Congress (2015-17), there were 16 Latter-day Saints in Congress; now, there are nine. All are Republicans.
