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.
Mormons
continue to hold 15 seats (about 3%), the same as in the previous Congress.
Protestants,
Catholics, Jews and Mormons each make up a greater percentage of the members of
Congress than of all U.S. adults. The same is true for some subgroups 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.2
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 an 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.

Congress’ First Hindu
and Other Firsts
Hawaii
Democrat Tulsi Gabbard is the first Hindu in either the House of
Representatives or the Senate.3
Gabbard, an Iraq War veteran who has served on the Honolulu City Council and in
the Hawaii state legislature, represents Hawaii’s 2nd congressional district.
Gabbard takes over the seat held in the 112th Congress by Rep. Mazie K. Hirono
(D), who on Nov. 6, 2012, became the first Buddhist elected to the Senate.
In
2006, Hirono and Rep. Hank Johnson (D-Ga.) became the first Buddhists to be
elected to the House. Four years later, they were joined by a third Buddhist
member, Colleen Hanabusa (D-Hawaii). Johnson and Hanabusa were re-elected to
serve in the 113th Congress.
The
first Muslim to serve in either the House or the Senate, Rep. Keith Ellison
(D-Minn.), was elected in 2006. Rep. Andre Carson (D-Ind.) became the second
Muslim in Congress when he won a special election in 2008. In 2012, Michigan
Democrat Syed Taj lost his bid to become the third Muslim member of Congress.
Ellison and Carson were re-elected.
Members
of other small religious groups started serving in Congress more than a century
ago. The first Jewish member arrived in 1845, when Lewis Charles Levin of the
American Party began representing Pennsylvania in the House. The first Mormon
in Congress, John Milton Bernhisel, began serving in 1851, after Utah was
officially recognized as a territory. California Democrat Dalip Singh Saund,
the first and so far only Sikh to serve in Congress, served three terms
starting in 1957.
Rep.
Pete Stark (D-Calif.), a Unitarian who joined Congress in 1973, became the
first member of Congress to publicly declare, in 2007, that he does not believe
in a Supreme Being. He lost his re-election bid in 2012.
The New, 113th Congress
Of
the 533 members of the new Congress, 299 are Protestant, which is about the
same percentage (56%) as in the 112th Congress (57%) and higher than the share
of Protestants in the U.S. adult population (48%). But the proportion of
Protestants in Congress has been in gradual decline for decades, and the number
in the 113th Congress is lower than the number in the previous Congress (307),
even if the difference in percentage terms is slight.

There
have been modest changes in congressional representation within Protestant
denominational families. Most notably, in the new Congress the number of
Baptists increased by five and the number of Methodists decreased by five.
Nonetheless, these two groups remain the largest Protestant subgroups, as in
the 112th Congress. The percentage of Methodists is slightly higher in Congress
(about 9%) than in the general public (around 6%); the reverse is true for
Baptists (14% of Congress and roughly 17% of all adults). The next-largest
Protestant groups are Presbyterians and Episcopalians; both are more than five
percentage points more numerous in Congress than among the general population.4
Protestants
who do not specify a particular denomination (58 members) also comprise a large
proportion of Congress (11%). It is unclear what percentage of these
unspecified Protestants are affiliated with nondenominational churches; just
three members of the 113th Congress specify that they belong to
nondenominational Protestant churches.
Meanwhile,
the number of Catholics in the 113th Congress has risen to 163, up from 156 in the
previously elected body. If Protestants are not counted together but as
separate denominations, then Catholics are the largest religious group in the
113th Congress. They represent more than 30% of the members in the 113th, compared
with 29% in the previous Congress. About a fifth of the U.S. adult population
(22%) is Catholic.
The
number of Jewish members of Congress decreased from 39 to 33. There are 11 Jewish
senators and 22 Jewish members of the House in the 113th Congress. Jews now
make up 6% of Congress (down from 7% in the 112th Congress). But this is still about
three times the Jewish share of the general population (2%).
The
number of Mormons in the 113th Congress (15) is the same as in the 112th, and
they are slightly more prevalent in Congress (almost 3%) than in the public at
large (2%).
As
previously mentioned, some other small religious groups are about as
numerically well-represented on Capitol Hill as in the general population.
Muslims account for less than 1% of the U.S. adult population and make up 0.4%
of Congress. Similarly, Buddhists and Hindus (also less than 1% of the U.S.
adult population) make up 0.6% and 0.2% of Congress, respectively. Orthodox
Christians also make up less than 1% of U.S. adults and comprise 0.9% of
Congress. There are no Jehovah’s Witnesses in Congress; the group has a relatively
small presence (less than 1%) in the U.S. population as a whole.
Differences by Chamber
Several
religious groups are represented in roughly equal proportions in both houses of
Congress, including Methodists (9% in the House, 8% in the Senate) and
Lutherans (4% in the House, 5% in the Senate).
However,
a few religious groups continue to have lopsided representation in one chamber
or the other. For example, Jews make up 11% of the new Senate but 5% of the
House. Likewise, Mormons make up 7% of the Senate and 2% of the House.
Presbyterians make up more than twice as much of the Senate as the House (15%
vs. 7%). The share of Baptists, by contrast, is greater in the House (15%) than
in the Senate (9%), as is the percentage of Episcopalians (8% vs. 4%).

Differences by Party
Affiliation
Overall,
48% of the members of the new Congress are Democrats, and 52% are Republicans.
Looking
at the partisan breakdown of the various religious groups, Lutherans are almost
evenly divided between the parties (52% Democrats and 48% Republicans). The
other sizable Protestant groups (Baptists, Methodists, Presbyterians and
Episcopalians) – as well as Protestants as a whole – have more Republicans than
Democrats. The same is true for Mormons; 12 of the 15 Mormon members of the new
Congress are Republicans. Catholics are slightly tilted toward the Democrats
(57%-43%). Jewish members are mostly Democratic (97%); in fact, House Majority
Leader Eric Cantor is the only Jewish Republican in Congress. The other
non-Christian groups (Buddhists, Muslims, Hindus and Unitarians) are comprised
exclusively of Democrats. All the members of Congress who did not specify a
religion are also Democrats.
Looking
at the religious breakdown of the political parties, 69% of congressional
Republicans are Protestant, while fewer than half of Democrats (42%) belong to
Protestant denominational families. (This includes newly elected independent
Angus King of Maine, who has said he will caucus with Senate Democrats.) On the
other hand, Catholics make up a greater share of Democratic members (37%) than
they do of GOP members (25%). And while Jews make up 13% of all congressional
Democrats (including one independent who generally caucuses with the Democrats,
Sen. Bernie Sanders of Vermont), they account for less than 1% of congressional
Republicans.

First-Time Members
The
85 members to be seated for the first time in 2013 are less Protestant than the
112 first-time members who entered in 2011.5
In the 112th Congress, about six-in-ten members of the congressional freshman
class were Protestant (59%), but that figure dipped to less than 50% in the 113th
Congress. The percentage of freshman members who are Baptist and Presbyterian
also decreased (from 16% to 9% for Baptists and from 8% to 4% for
Presbyterians).
Catholics
comprise a higher percentage of first-time members (37%) than of incumbent
members (30%). Likewise, unspecified Protestants make up a greater percentage
of freshman members (19%) than of incumbents (9%).
The
reverse is true for many other groups. About 4% of first-time members are
Jewish, compared with 7% of incumbents. Presbyterians also make up a somewhat larger
share of incumbents (9%) than of freshman members (4%). The same is true for
Baptists and Methodists.

Looking Back
In
many ways, the changes in the religious makeup of Congress during the last
half-century mirror broader changes in American society. Congress, like the
nation as a whole, has become much less Protestant and more religiously
diverse. The number of Protestants in Congress has dropped from three-quarters
(75%) in 1961 to 56% today, which roughly tracks with broader religious
demographic trends during this period. As recently as the 1980s, General Social
Surveys found that about six-in-ten Americans identified themselves as
Protestants. In aggregated surveys conducted by the Pew Research Center in 2012
and reported in the Pew Forum’s October 2012 report “‘Nones’ on
the Rise,” the share of self-identified Protestants has dipped to just
under half (48%).
Likewise,
many of the major Protestant denominational families have lost ground in
Congress in the past 50 years. Methodists, who made up nearly one-in-five
members (18%) of the 87th Congress, which was seated in 1961, make up 9% of the
113th Congress. Some other Protestant denominational families also have seen a
decline in their numerical representation in Congress. For example,
Episcopalians have gone from 12% to 7% and Congregationalists from 5% to less
than 1% during this period.
A
few Protestant groups have fared somewhat better, however. From 1961 to today,
the proportion of Baptists in Congress has increased slightly from 12% to 14%,
and the Lutheran share has stayed roughly the same (around 4%).
Meanwhile,
other religious groups have seen their share of congressional seats grow, in
some cases dramatically. Catholics, for instance, have gone from 19% of the
congressional membership in 1961 to 31% today. The percentage of Jewish members
of Congress has risen from 2% in 1961 to 6% today.

Footnotes:
1 This analysis is based on the 533 members of the 113th Congress scheduled to be
sworn in on Jan. 3. It excludes the seat formerly held by Illinois Rep. Jesse
Jackson Jr. (Baptist), who was re-elected in November 2012 but has since
resigned. It also excludes the House seat left vacant by South Carolina’s Tim
Scott (unspecified Protestant) when he was appointed in December 2012 to the
Senate seat formerly held by Jim DeMint (Presbyterian). Scott is counted among
the 113th Congress’ senators, as is new Hawaii Sen. Brian Schatz (Jewish), who
was appointed in December 2012 to fill the seat of the late Sen. Daniel Inouye
(Methodist). (return to text)
2 The categorization of 10 members’ religion as “unspecified” comes from queries
to their offices from CQ Roll Call, but other media outlets have described them
differently. For example, the National Journal classifies most of these members
as having “no affiliation” and lists Illinois congresswoman Tammy Duckworth as
a deist. Another member, Tammy Baldwin, a Democratic congresswoman from
Wisconsin who was elected to the Senate in 2012, was described in a November
2012 New
York Times article as someone who “does not discuss her religiosity.” If
Duckworth, Baldwin and the other “unspecified” members were counted with Sinema
as unaffiliated (or “none”), they would comprise about 2% of the new Congress.
This would still be well below the nearly 20% of all U.S. adults who say they
are unaffiliated, based on aggregated data from surveys conducted by the Pew
Research Center for the People & the Press in 2012 and reported in the Pew
Forum’s October 2012 report, “ ‘Nones’ on
the Rise.” (return to text)
3 Ami Bera, who was elected for the first time in 2012 to represent California’s
7th congressional district, was raised Hindu but now identifies as a Unitarian
Universalist. He is the only Unitarian Universalist in the 113th Congress. (return to text)
4 This analysis counts Christian Scientists as a Protestant denominational family
in both the 112th and 113th Congresses because that is how they are counted in
the Pew Research Center figures used for the general public. In previous Pew
Forum analyses of the religious affiliations of the members of Congress,
Christian Scientists were categorized as “Other Christians” because that is how
they were counted in the general public numbers at that time. (return to text)
5 The 85 freshmen include South Carolina’s Tim Scott, who was appointed in
December 2012 to the Senate seat formerly held by Jim DeMint, and Hawaii’s
Brian Schatz, who was appointed in December 2012 to the Senate seat formerly
held by the late Daniel Inouye. (return to text)
