"When it comes to religious affiliation, the 117th U.S. Congress looks similar to the previous Congress but quite different from Americans overall.
While about a quarter (26%) of U.S. adults are religiously unaffiliated – describing themselves as atheist, agnostic or “nothing in particular” – just one member of the new Congress (Sen. Kyrsten Sinema, D-Ariz.) identifies as religiously unaffiliated (0.2%).
Nearly nine-in-ten members of Congress identify as Christian (88%), compared with two-thirds of the general public (65%). Congress is both more heavily Protestant (55% vs. 43%) and more heavily Catholic (30% vs. 20%) than the U.S. adult population overall."
