Washington, D.C. – 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,” according to a new analysis by the Pew Research Center’s Forum on Religion & Public Life of congressional data compiled primarily by CQ Roll Call. This continues 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.
The new analysis shows that Catholics have seen the biggest gains among the 530 seats in the new Congress that have been decided as of Nov. 16. So far, Catholics have picked up five seats, for a total of 161, raising their share to just over 30%. The biggest decline is among Jews, who have been elected to 32 seats (6%), seven fewer than in the 112th Congress, where Jews held 39 seats (7%). Mormons continue to hold 15 seats (about 3%), the same as in the previous Congress.
Protestants also appear likely to continue to occupy about the same proportion of seats as in the 112th Congress (56%). 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 elected for the first time in 2012 are less Protestant than the group first elected in 2010; 48% are Protestant, compared with 59% of those elected for the first time in 2010.
Protestants, Catholics and Jews each make up a greater percentage of the members of Congress than of all U.S. adults. The same is true for some sub-groups of Protestants, such as Episcopalians and Presbyterians. By contrast, Pentecostals are a much smaller percentage of Congress than of the general public. Due in part to electoral gains in recent years, Buddhists, Muslims and Hindus now are represented in Congress in closer proportion to their numbers in the U.S. adult population. But some small religious groups, such as Jehovah’s Witnesses, are not represented at all in Congress.
Perhaps the greatest disparity, however, is between the percentage of U.S. adults and the percentage of members of Congress who do not identify with any particular religion. About one-in-five U.S. adults describe themselves as atheist, agnostic or “nothing in particular” – a group sometimes collectively called the “nones.” But only one member of the new Congress, Kyrsten Sinema (D-Ariz.), is religiously unaffiliated, according to information gathered by CQ Roll Call. Sinema is the first member of Congress to publicly describe her religion as “none,” though 10 other members of the 113th Congress (about 2%) do not specify a religious affiliation, up from six members (about 1%) of the previous Congress. This is about the same as the percentage of U.S. adults in Pew Research Center surveys who say that they don’t know, or refuse to specify, their faith (about 2%).
These are some of the findings from a new analysis by the Pew Research Center’s Forum on Religion & Public Life of congressional data compiled primarily by CQ Roll Call. The analysis compares the religious affiliations of members of the new Congress with Pew Research Center survey data on the U.S. public. CQ Roll Call gathered information on the religious affiliations of members of Congress through questionnaires and follow-up phone calls to members’ and candidates’ offices, and the Pew Forum supplemented this with additional research.
The full analysis, including a downloadable graphic depicting the religious makeup of the new Congress, is available on the Pew Forum’s website.
The Pew Research Center’s Forum on Religion & Public Life conducts surveys, demographic analyses and other social science research on important aspects of religion and public life in the U.S. and around the world. The Pew Hispanic Center is a nonpartisan research organization that seeks to improve understanding of the U.S. Hispanic population and to chronicle Latinos’ growing impact on the nation. Both are projects of the Washington-based Pew Research Center, a nonpartisan, non-advocacy “fact-tank” that does not take positions on policy debates or any of the issues it covers.
