The new, 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,” continuing a gradual increase in religious diversity that mirrors trends in the country as a whole. While Congress remains majority Protestant, the institution is far less so today than it was 50 years ago, when nearly three-quarters of the members belonged to Protestant denominations.
Catholics have seen the biggest gains among the 533 members who are scheduled to be sworn in on Jan. 3.1 Catholics picked up seven seats, for a total of 163, raising their share to just over 30%. Protestants and Jews experienced the biggest declines in numerical terms. Jews now hold 33 seats (6%), six fewer than in the 112th Congress, where Jews held 39 seats (7%). Protestants lost eight seats, though they continue to occupy about the same proportion of seats (56%) as in the 112th Congress (57%).
In addition, the Protestant share of each political party in the new Congress is about the same as in the 112th; roughly seven-in-ten Republicans are Protestants, compared with fewer than half of Democrats. However, the members sworn in for the first time in 2013 are less Protestant than the group that entered in 2011; 48% are Protestant, compared with 59% of the previous freshmen.
