Faith on the Hill
While there has been a decades-long decline in the Christian share of U.S. adults, 88% of the voting members in the new 118th Congress identify as Christian. That is only a few points lower than their share in the late 1970s.
Since the 1990s, large numbers of Americans have left Christianity to join the growing ranks of U.S. adults who describe their religious identity as atheist, agnostic or “nothing in particular.” If recent trends in religious switching continue, Christians could make up less than half of the U.S. population within a few decades.
