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.
When it comes to religious affiliation, the 117th U.S. Congress looks similar to the previous Congress but quite different from Americans overall.
The new, 116th Congress includes the first two Muslim women ever to serve in the House of Representatives, and is, overall, slightly more religiously diverse than the prior Congress.
More than nine-in-ten members of the newly elected 114th Congress are Christian — a significantly higher share than is seen in the general population. However, many other major religious groups are represented in the body, including Jews, Buddhists, Muslims, Hindus and the unaffiliated.
The newly elected 113th Congress includes the first Buddhist to serve in the Senate, the first Hindu to serve in either chamber and the first member of Congress to describe her religion as “none.” While Congress remains majority Protestant, the institution is far less so today than it was 50 years ago.
The political overhaul of the U.S. Congress after the 2010 elections appears to have had little effect on the religious composition of the legislative body, which is similar to the religious makeup of the previous Congress and of the nation, according to an analysis by the Pew Forum.
