Religion in the United States is characterized by a diversity of religious beliefs and practices. Various religious faiths have flourished within the United States. A majority of Americans report that religion plays a very important role in their lives, a proportion unique among developed countries.
Historically, the United States has always been marked by religious pluralism and diversity, beginning with various native beliefs of the pre-colonial time. In colonial times, Anglicans, Catholics and mainline Protestants, as well as Jews, arrived from Europe. Eastern Orthodoxy has been present since the Russian colonization of Alaska. Various dissenting Protestants, who left the Church of England, greatly diversified the religious landscape. The Great Awakenings gave birth to multiple Evangelical Protestant denominations; membership in Methodist and Baptist churches increased drastically in the Second Great Awakening. In the 18th century, deism found support among American upper classes and thinkers. The Episcopal Church, splitting from the Church of England, came into being in the American Revolution. New Protestant branches like Adventism emerged; Restorationists and other Christians like the Jehovah's Witnesses, the Latter Day Saint movement, Churches of Christ and Church of Christ, Scientist, as well as Unitarian and Universalist communities all spread in the 19th century. Pentecostalism emerged in the early 20th century as a result of the Azusa Street Revival. Scientology emerged in the 1950s. Unitarian Universalism resulted from the merge of Unitarian and Universalist churches in the 20th century. Beginning in 1990s, the religious share of Christians is decreasing due to secularization, while Buddhism, Hinduism, Islam, and other religions are spreading. Protestantism, historically dominant, ceased to be the religious category of the majority in the early 2010s.
The majority of U.S. adults self-identify as Christians, while close to a quarter claim no religious affiliation. According to a 2014 study by the Pew Research Center, 70.6% of the adult population identified themselves as Christians, with 46.5% professing attendance at a variety of churches that could be considered Protestant, and 20.8% professing Catholic beliefs. The same study says that other religions (including Judaism, Buddhism, Hinduism, and Islam) collectively make up about 6% of the population. According to a 2012 survey by the Pew forum, 36% of U.S. adults state that they attend services nearly every week or more. According to a 2016 Gallup poll, Mississippi (with 63% of its adult population described as very religious, saying that religion is important to them and attending religious services almost every week) is the most religious state in the country, while New Hampshire (with only 20% of its adult population described as very religious) is the least religious state.
From early colonial days, when some English and German settlers came in search of religious freedom, America has been profoundly influenced by religion. That influence continues in American culture, social life, and politics. Several of the original Thirteen Colonies were established by settlers who wished to practice their own religion within a community of like-minded people: the Massachusetts Bay Colony was established by English Puritans (Congregationalists), Pennsylvania by British Quakers, Maryland by English Catholics, and Virginia by English Anglicans. Despite these, and as a result of intervening religious strife and preference in England the Plantation Act 1740 would set official policy for new immigrants coming to British America until the American Revolution.
The text of the First Amendment to the country's Constitution states that "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances." It guarantees the free exercise of religion while also preventing the government from establishing a state religion. However the states were not bound by the provision and as late as the 1830s Massachusetts provided tax money to local Congregational churches. The Supreme Court since the 1940s has interpreted the Fourteenth Amendment as applying the First Amendment to the state and local governments.
President John Adams and a unanimous Senate endorsed the Treaty of Tripoli in 1797 that stated: "the Government of the United States of America is not, in any sense, founded on the Christian religion."
According to a 2002 survey by the Pew Research Center, nearly 6 in 10 Americans said that religion plays an important role in their lives, compared to 33% in Great Britain, 27% in Italy, 21% in Germany, 12% in Japan, and 11% in France. The survey report stated that the results showed America having a greater similarity to developing nations (where higher percentages say that religion plays an important role) than to other wealthy nations, where religion plays a minor role.
The United States federal government was the first national government to have no official state-endorsed religion. However, some states had established religions in some form until the 1830s.
Modeling the provisions concerning religion within the Virginia Statute for Religious Freedom, the framers of the Constitution rejected any religious test for office, and the First Amendment specifically denied the federal government any power to enact any law respecting either an establishment of religion or prohibiting its free exercise, thus protecting any religious organization, institution, or denomination from government interference. The decision was mainly influenced by European Rationalist and Protestant ideals, but was also a consequence of the pragmatic concerns of minority religious groups and small states that did not want to be under the power or influence of a national religion that did not represent them.
The most popular religion in the U.S. is Christianity, comprising the majority of the population (70.6% of adults in 2014). According to the Association of Statisticians of American Religious Bodies newsletter published March 2017, based on data from 2010, Christians were the largest religious population in all 3,143 counties in the country. Roughly 46.5% of Americans are Protestants, 20.8% are Catholics, 1.6% are Mormons (the name commonly used to refer to members of The Church of Jesus Christ of Latter-day Saints), and 1.7% have affiliations with various other Christian denominations. Christianity was introduced during the period of European colonization.
The Southern Baptist Convention, with over 16 million adherents, is the largest of more than 200 distinctly named Protestant denominations. In 2007, members of evangelical churches comprised 26% of the American population, while another 18% belonged to mainline Protestant churches, and 7% belonged to historically black churches.
A 2015 study estimates some 450,000 Christian believers from a Muslim background in the country, most of them belonging to some form of Protestantism. In 2010 there were approximately 180,000 Arab Americans and about 130,000 Iranian Americans who converted from Islam to Christianity. Dudley Woodbury, a Fulbright scholar of Islam, estimates that 20,000 Muslims convert to Christianity annually in the United States.
Historians agree that members of mainline Protestant denominations have played leadership roles in many aspects of American life, including politics, business, science, the arts, and education. They founded most of the country's leading institutes of higher education. According to Harriet Zuckerman, 72% of American Nobel Prize Laureates between 1901 and 1972, have identified from Protestant background.
Episcopalians and Presbyterians tend to be considerably wealthier and better educated than most other religious groups, and numbers of the most wealthy and affluent American families as the Vanderbilts and Astors,Rockefeller,Du Pont, Roosevelt, Forbes, Whitneys,Morgans and Harrimans are Mainline Protestant families, though those affiliated with Judaism are the wealthiest religious group in the United Statesand those affiliated with Catholicism, owing to sheer size, have the largest number of adherents of all groups in the top income bracket.
Some of the first colleges and universities in America, including Harvard,Yale,Princeton,Columbia,Dartmouth,Williams, Bowdoin, Middlebury, and Amherst, all were founded by mainline Protestant denominations. By the 1920s most had weakened or dropped their formal connection with a denomination. James Hunter argues that:
Beginning in the 16th century, the Spanish (and later the French and English) introduced Catholicism. From the 19th century to the present, Catholics came to the US in large numbers due to immigration of Italians, Hispanics, Portuguese, French, Polish, Irish, Highland Scots, Dutch, Flemish, Hungarians, Germans, Lebanese (Maronite), and other ethnic groups.
Several Christian groups were founded in America during the Great Awakenings. Interdenominational evangelicalism and Pentecostalism emerged; new Protestant denominations such as Adventism; non-denominational movements such as the Restoration Movement (which over time separated into the Churches of Christ, the Christian churches and churches of Christ, and the Christian Church (Disciples of Christ)); Jehovah's Witnesses (called "Bible Students" in the latter part of the 19th century); and The Church of Jesus Christ of Latter-day Saints (Mormonism).
The strength of various sects varies greatly in different regions of the country, with rural parts of the South having many evangelicals but very few Catholics (except Louisiana and the Gulf Coast, and from among the Hispanic community, both of which consist mainly of Catholics), while urbanized areas of the north Atlantic states and Great Lakes, as well as many industrial and mining towns, are heavily Catholic, though still quite mixed, especially due to the heavily Protestant African-American communities. In 1990, nearly 72% of the population of Utah was Mormon, as well as 26% of neighboring Idaho. Lutheranism is most prominent in the Upper Midwest, with North Dakota having the highest percentage of Lutherans (35% according to a 2001 survey).
The largest religion, Christianity, has proportionately diminished since 1990. While the absolute number of Christians rose from 1990 to 2008, the percentage of Christians dropped from 86% to 76%. A nationwide telephone interview of 1,002 adults conducted by The Barna Group found that 70% of American adults believe that God is "the all-powerful, all-knowing creator of the universe who still rules it today", and that 9% of all American adults and 0.5% young adults hold to what the survey defined as a "biblical worldview".
Episcopalian, Presbyterian, Eastern Orthodox and United Church of Christ members have the highest number of graduate and post-graduate degrees per capita of all Christian denominations in the United States, as well as the most high-income earners.However, owing to the sheer size or demographic head count of Catholics, more individual Catholics have graduate degrees and are in the highest income brackets than have or are individuals of any other religious community.
After Christianity, Judaism is the next largest religious affiliation in the US, though this identification is not necessarily indicative of religious beliefs or practices. There are between 5.3 and 6.6 million Jews. A significant number of people identify themselves as American Jews on ethnic and cultural grounds, rather than religious ones. For example, 19% of self-identified American Jews do not believe God exists. The 2001 ARIS study projected from its sample that there are about 5.3 million adults in the American Jewish population: 2.83 million adults (1.4% of the U.S. adult population) are estimated to be adherents of Judaism; 1.08 million are estimated to be adherents of no religion; and 1.36 million are estimated to be adherents of a religion other than Judaism. ARIS 2008 estimated about 2.68 million adults (1.2%) in the country identify Judaism as their faith.
Jews have been present in what is now the US since the 17th century, and specifically allowed since the British colonial Plantation Act 1740. Although small Western European communities initially developed and grew, large-scale immigration did not take place until the late 19th century, largely as a result of persecutions in parts of Eastern Europe. The Jewish community in the United States is composed predominantly of Ashkenazi Jews whose ancestors emigrated from Central and Eastern Europe. There are, however, small numbers of older (and some recently arrived) communities of Sephardi Jews with roots tracing back to 15th century Iberia (Spain, Portugal, and North Africa). There are also Mizrahi Jews (from the Middle East, Caucasia and Central Asia), as well as much smaller numbers of Ethiopian Jews, Indian Jews, Kaifeng Jews and others from various smaller Jewish ethnic divisions. Approximately 25% of the Jewish American population lives in New York City.
According to the Association of Statisticians of American Religious Bodies newsletter published March, 2017, based on data from 2010, Jews were the largest minority religion in 231 counties out of the 3143 counties in the country. According to a 2014 survey conducted by the Pew Forum on Religion and Public life, 1.7% of adults in the U.S. identify Judaism as their religion. Among those surveyed, 44% said they were Reform Jews, 22% said they were Conservative Jews, and 14% said they were Orthodox Jews. According to the 1990 National Jewish Population Survey, 38% of Jews were affiliated with the Reform tradition, 35% were Conservative, 6% were Orthodox, 1% were Reconstructionists, 10% linked themselves to some other tradition, and 10% said they are "just Jewish".
The Pew Research Center report on American Judaism released in October 2013 revealed that 22% of Jewish Americans say they have "no religion" and the majority of respondents do not see religion as the primary constituent of Jewish identity. 62% believe Jewish identity is based primarily in ancestry and culture, only 15% in religion. Among Jews who gave Judaism as their religion, 55% based Jewish identity on ancestry and culture, and 66% did not view belief in God as essential to Judaism.
A 2009 study estimated the Jewish population (including both those who define themselves as Jewish by religion and those who define themselves as Jewish in cultural or ethnic terms) to be between 6.0 and 6.4 million. According to a study done in 2000 there were an estimated 6.14 million Jewish people in the country, about 2% of the population.
According to the 2001 National Jewish Population Survey, 4.3 million American Jewish adults have some sort of strong connection to the Jewish community, whether religious or cultural. Jewishness is generally considered an ethnic identity as well as a religious one. Among the 4.3 million American Jews described as "strongly connected" to Judaism, over 80% have some sort of active engagement with Judaism, ranging from attendance at daily prayer services on one end of the spectrum to attending Passover Seders or lighting Hanukkah candles on the other. The survey also discovered that Jews in the Northeast and Midwest are generally more observant than Jews in the South or West. Reflecting a trend also observed among other religious groups, Jews in the Northwestern United States are typically the least observant of tradition.
The Jewish American community has higher household incomes than average, and is one of the best educated religious communities in the United States.
Islam is the third largest faith in the United States, after Christianity and Judaism, representing 0.9% of the population. According to the Association of Statisticians of American Religious Bodies newsletter published March, 2017, based on data from 2010, Muslims were the largest minority religion in 392 counties out of the 3143 counties in the country. Islam in America effectively began with the arrival of African slaves. It is estimated that about 10% of African slaves transported to the United States were Muslim. Most, however, became Christians, and the United States did not have a significant Muslim population until the arrival of immigrants from Arab and East Asian Muslim areas. According to some experts, Islam later gained a higher profile through the Nation of Islam, a religious group that appealed to black Americans after the 1940s; its prominent converts included Malcolm X and Muhammad Ali. The first Muslim elected in Congress was Keith Ellison in 2006, followed by André Carson in 2008.
Research indicates that Muslims in the United States are generally more assimilated and prosperous than their counterparts in Europe. Like other subcultural and religious communities, the Islamic community has generated its own political organizations and charity organizations.
The United States has perhaps the second largest Bahá'í community in the world. First mention of the faith in the U.S. was at the inaugural Parliament of World Religions, which was held at the Columbian Exposition in Chicago in 1893. In 1894, Ibrahim George Kheiralla, a Syrian Bahá'í immigrant, established a community in the U.S. He later left the main group and founded a rival movement. According to the Association of Statisticians of American Religious Bodies newsletter published March, 2017, based on data from 2010, Bahá'ís were the largest minority religion in 80 counties out of the 3143 counties in the country.
Rastafarians began migrating to the United States in the 1950s, '60s and '70s from the religion's 1930s birthplace, Jamaica.Marcus Garvey, who is considered a prophet by many Rastafarians, rose to prominence and cultivated many of his ideas in the United States.
During the late 19th century Buddhist missionaries from Japan came to the US. During the same time period, US intellectuals started to take interest in Buddhism.
The first prominent US citizen to publicly convert to Buddhism was Henry Steel Olcott in 1880. An event that contributed to the strengthening of Buddhism in the US was the Parliament of the World's Religions in 1893, which was attended by many Buddhist delegates sent from India, China, Japan, Vietnam, Thailand and Sri Lanka.
The early 20th century was characterized by a continuation of tendencies that had their roots in the 19th century. The second half, by contrast, saw the emergence of new approaches, and the move of Buddhism into the mainstream and making itself a mass and social religious phenomenon.
Estimates of the number of Buddhists in the United States vary between 0.5% and 0.9%, with 0.7% reported by both the CIA and Pew. According to the Association of Statisticians of American Religious Bodies newsletter published March, 2017, based on data from 2010, Buddhists were the largest minority religion in 186 counties out of the 3143 counties in the country.
Hinduism is the fourth largest faith in the United States, representing 0.7% of the population. The first time Hinduism entered the U.S. is not clearly identifiable. However, large groups of Hindus have immigrated from India and other Asian countries since the enactment of the Immigration and Nationality Act of 1965. During the 1960s and 1970s Hinduism exercised fascination contributing to the development of New Age thought. During the same decades the International Society for Krishna Consciousness (a Vaishnavite Hindu reform organization) was founded in the US.
In 2001, there were an estimated 766,000 Hindus in the US, about 0.2% of the total population. According to the Association of Statisticians of American Religious Bodies newsletter published March, 2017, based on data from 2010, Bahá'ís were the largest minority religion in 92 counties out of the 3143 counties in the country.
In 2004 the Hindu American Foundation--a national institution protecting rights of the Hindu community of U.S.--was founded.
American Hindus have one of the highest rates of educational attainment and household income among all religious communities, and tend to have lower divorce rates.
Adherents of Jainism first arrived in the United States in the 20th century. The most significant time of Jain immigration was in the early 1970s. The United States has since become a center of the Jain Diaspora. The Federation of Jain Associations in North America is an umbrella organization of local American and Canadian Jain congregations to preserve, practice, and promote Jainism and the Jain way of life.
Sikhism is a religion originating from South Asia (predominantly in modern-day India) which was introduced into the United States when, around the turn of the 20th century, Sikhs started emigrating to the United States in significant numbers to work on farms in California. They were the first community to come from India to the US in large numbers.[clarification needed] The first Sikh Gurdwara in America was built in Stockton, California, in 1912. In 2007, there were estimated to be between 250,000 and 500,000 Sikhs living in the United States, with the largest populations living on the East and West Coasts, with additional populations in Detroit, Chicago, and Austin.
The United States also has a number of non-Punjabi converts to Sikhism.
In 2004 there were an estimated 56,000 Taoists in the US. Taoism was popularized throughout the world through the writings and teachings of Lao Tzu and other Taoists as well as the practice of Qigong, Tai Chi Chuan and other Chinese martial arts.
This group includes atheists, agnostics and people who describe their religion as "nothing in particular".
"Unaffiliated" does not necessarily mean "non-religious". Some people who are unaffiliated with any particular religion express religious beliefs (such as belief in one or more gods or in reincarnation) and engage in religious practices (such as prayer).
A 2001 survey directed by Dr. Ariela Keysar for the City University of New York indicated that, amongst the more than 100 categories of response, "no religious identification" had the greatest increase in population in both absolute and percentage terms. This category included atheists, agnostics, humanists, and others with no stated religious preferences. Figures are up from 14.3 million in 1990 to 34.2 million in 2008, representing an increase from 8% of the total population in 1990 to 15% in 2008. A nationwide Pew Research study published in 2008 put the figure of unaffiliated persons at 16.1%, while another Pew study published in 2012 was described as placing the proportion at about 20% overall and roughly 33% for the 18-29-year-old demographic.
In a 2006 nationwide poll, University of Minnesota researchers found that despite an increasing acceptance of religious diversity, atheists were generally distrusted by other Americans, who trusted them less than Muslims, recent immigrants and other minority groups in "sharing their vision of American society". They also associated atheists with undesirable attributes such as amorality, criminal behavior, rampant materialism and cultural elitism. However, the same study also reported that "The researchers also found acceptance or rejection of atheists is related not only to personal religiosity, but also to one's exposure to diversity, education and political orientation - with more educated, East and West Coast Americans more accepting of atheists than their Midwestern counterparts." Some surveys have indicated that doubts about the existence of the divine were growing quickly among Americans under 30.
On 24 March 2012, American atheists sponsored the Reason Rally in Washington, D.C., followed by the American Atheist Convention in Bethesda, Maryland. Organizers called the estimated crowd of 8,000-10,000 the largest-ever US gathering of atheists in one place.
In the United States, Enlightenment philosophy (which itself was heavily inspired by deist ideals) played a major role in creating the principle of religious freedom, expressed in Thomas Jefferson's letters and included in the First Amendment to the United States Constitution. American Founding Fathers, or Framers of the Constitution, who were especially noted for being influenced by such philosophy of deism include Thomas Jefferson, Benjamin Franklin, Cornelius Harnett, Gouverneur Morris, and Hugh Williamson. Their political speeches show distinct deistic influence. Other notable Founding Fathers may have been more directly deist. These include Thomas Paine, James Madison, possibly Alexander Hamilton, and Ethan Allen.
Various polls have been conducted to determine Americans' actual beliefs regarding a god:
"Spiritual but not religious" (SBNR) is self-identified stance of spirituality that takes issue with organized religion as the sole or most valuable means of furthering spiritual growth. Spirituality places an emphasis upon the wellbeing of the "mind-body-spirit," so holistic activities such as tai chi, reiki, and yoga are common within the SBNR movement. In contrast to religion, spirituality has often been associated with the interior life of the individual.
One fifth of the US public and a third of adults under the age of 30 are reportedly unaffiliated with any religion, however they identify as being spiritual in some way. Of these religiously unaffiliated Americans, 37% classify themselves as spiritual but not religious.
Many other religions are represented in the United States, including Shinto, Caodaism, Thelema, Santería, Kemetism, Religio Romana, Kaldanism, Zoroastrianism, Vodou, Pastafarianism, and many forms of New Age spirituality.
Native American religions historically exhibited much diversity, and are often characterized by animism or panentheism. The membership of Native American religions in the 21st century comprises about 9,000 people.
Neopaganism in the United States is represented by widely different movements and organizations. The largest Neopagan religion is Wicca, followed by Neo-Druidism. Other neopagan movements include Germanic Neopaganism, Celtic Reconstructionist Paganism, Hellenic Polytheistic Reconstructionism, and Semitic neopaganism.
According to the American Religious Identification Survey (ARIS), there are approximately 30,000 druids in the United States. Modern Druidism came to North America first in the form of fraternal Druidic organizations in the nineteenth century, and orders such as the Ancient Order of Druids in America were founded as distinct American groups as early as 1912. In 1963, the Reformed Druids of North America (RDNA) was founded by students at Carleton College, Northfield, Minnesota. They adopted elements of Neopaganism into their practices, for instance celebrating the festivals of the Wheel of the Year.
Wicca advanced in North America in the 1960s by Raymond Buckland, an expatriate Briton who visited Gardner's Isle of Man coven to gain initiation.Universal Eclectic Wicca was popularized in 1969 for a diverse membership drawing from both Dianic and British Traditional Wiccan backgrounds.
A group of churches which started in the 1830s in the United States is known under the banner of "New Thought". These churches share a spiritual, metaphysical and mystical predisposition and understanding of the Bible and were strongly influenced by the Transcendentalist movement, particularly the work of Ralph Waldo Emerson. Another antecedent of this movement was Swedenborgianism, founded on the writings of Emanuel Swedenborg in 1787. The New Thought concept was named by Emma Curtis Hopkins ("teacher of teachers") after Hopkins broke off from Mary Baker Eddy's Church of Christ, Scientist. The movement had been previously known as the Mental Sciences or the Christian Sciences. The three major branches are Religious Science, Unity Church and Divine Science.
Unitarian Universalists do not share a creed; rather, they are unified by their shared search for spiritual growth and by the understanding that an individual's theology is a result of that search and not obedience to an authoritarian requirement.
The First Amendment guarantees both the free practice of religion and the non-establishment of religion by the federal government (later court decisions have extended that prohibition to the states). The U.S. Pledge of Allegiance was modified in 1954 to add the phrase "under God", in order to distinguish itself from the state atheism espoused by the Soviet Union.
Various American presidents have often stated the importance of religion. On February 20, 1955, President Dwight D. Eisenhower stated that "Recognition of the Supreme Being is the first, the most basic, expression of Americanism." President Gerald Ford agreed with and repeated this statement in 1974.
The U.S. Census does not ask about religion. Various groups have conducted surveys to determine approximate percentages of those affiliated with each religious group.
|Affiliation||% of U.S. population|
|Other non-Christian religion||2.5|
|No response given||2.6|
|Affiliation||% of U.S. population|
|Nothing in particular||15.8|
|Other Non-Christian faiths||1.8|
|Don't know/refused answer||0.6|
|Religion in the United States (1962-2012)|
|Date||Christianity||Protestantism||Catholicism||Other Christian groups||Non-Christian groups||Non-religious/Non-response|
In 2006, an online Harris Poll (they stated that the magnitude of errors cannot be estimated due to sampling errors, non-response, etc.; 2,010 U.S. adults were surveyed) found that 26% of those surveyed attended religious services "every week or more often", 9% went "once or twice a month", 21% went "a few times a year", 3% went "once a year", 22% went "less than once a year", and 18% never attend religious services.
In a 2009 Gallup International survey, 41.6% of American citizens said that they attended a church, synagogue, or mosque once a week or almost every week. This percentage is higher than other surveyed Western countries.Church attendance varies considerably by state and region. The figures, updated to 2014, ranged from 51% in Utah to 17% in Vermont.
|47||District of Columbia||23%|
In August 2010, 67% of Americans said religion was losing influence, compared with 59% who said this in 2006. Majorities of white evangelical Protestants (79%), white mainline Protestants (67%), black Protestants (56%), Catholics (71%), and the religiously unaffiliated (62%) all agreed that religion was losing influence on American life; 53% of the total public said this was a bad thing, while just 10% see it as a good thing.
Politicians frequently discuss their religion when campaigning, and fundamentalists and black Protestants are highly politically active. However, to keep their status as tax-exempt organizations they must not officially endorse a candidate. Historically Catholics were heavily Democratic before the 1970s, while mainline Protestants comprised the core of the Republican Party. Those patterns have faded away--Catholics, for example, now split about 50-50. However, white evangelicals since 1980 have made up a solidly Republican group that favors conservative candidates. Secular voters are increasingly Democratic.
Only three presidential candidates for major parties have been Catholics, all for the Democratic party:
Joe Lieberman was the first major presidential candidate that was Jewish, on the Gore-Lieberman campaign of 2000 (although John Kerry and Barry Goldwater both had Jewish ancestry, they were practicing Christians). Bernie Sanders ran against Hillary Clinton in the Democratic primary of 2016. He was the first major Jewish candidate to compete in the presidential primary process. However, Sanders noted during the campaign that he does not actively practice any religion.
In 2006 Keith Ellison of Minnesota became the first Muslim elected to Congress; when re-enacting his swearing-in for photos, he used the copy of the Qur'an once owned by Thomas Jefferson.André Carson is the second Muslim to serve in Congress.
A Gallup poll released in 2007 indicated that 53% of Americans would refuse to vote for an atheist as president, up from 48% in 1987 and 1999. But then the number started to drop again and reached record low 43% in 2012 and 40% in 2015. 
The 2012 Republican presidential nominee Mitt Romney is Mormon and a member of The Church of Jesus Christ of Latter-day Saints. He is the former governor of the state of Massachusetts, and his father George Romney was the governor of the state of Michigan. The Romneys were involved in Mormonism in their states and in the state of Utah.
The table below is based mainly on data reported by individual denominations to the Yearbook of American and Canadian Churches, and published in 2011 by the National Council of Churches of Christ in USA. It only includes religious bodies reporting 60,000 or more members. The definition of a member is determined by each religious body.

The Association of Religion Data Archives (ARDA) surveyed congregations for their memberships. Churches were asked for their membership numbers. Adjustments were made for those congregations that did not respond and for religious groups that reported only adult membership. ARDA estimates that most of the churches not responding were black Protestant congregations. Significant difference in results from other databases include the lower representation of adherents of 1) all kinds (62.7%), 2) Christians (59.9%), 3) Protestants (less than 36%); and the greater number of unaffiliated (37.3%).

The United States government does not collect religious data in its census. The survey below, the American Religious Identification Survey (ARIS) of 2008, was a random digit-dialed telephone survey of 54,461 American residential households in the contiguous United States. The 1990 sample size was 113,723; 2001 sample size was 50,281.
Adult respondents were asked the open-ended question, "What is your religion, if any?" Interviewers did not prompt or offer a suggested list of potential answers. The religion of the spouse or partner was also asked. If the initial answer was "Protestant" or "Christian" further questions were asked to probe which particular denomination. About one third of the sample was asked more detailed demographic questions.

Figures are not adjusted for refusals to reply; investigators suspect refusals are possibly more representative of "no religion" than any other group.

The inclusion of "under God" in the Pledge, the report says, "would serve to deny the atheistic and materialistic conceptions of communism with its attendant subservience of the individual".
The United States, wanting to distinguish itself from the USSR and its atheist positions, went to great extremes to demonstrate that God was still supreme in this country.
In the early 1950s, a Presbyterian minister in New York gave a sermon in which he railed against the U.S. Pledge of Allegiance because it contained no references to God. According to the reverend, the American pledge could serve just as well in the atheistic Soviet Union; there was nothing in the U.S. pledge to distinguish it from an oath to the godless communist state. So in 1954, Congress passed a law that inserted the phrase "under God" into the Pledge of Allegiance.
Including God in the nation's pledge would send a clear message to the world that unlike communist regimes that denied God's existence, the United States recognized a Supreme Being. Official acknowledgement of God would further distinguish freedom-loving Americans from their atheist adversaries.
Recognition of the Supreme Being is the first, the most basic, expression of Americanism," he declared in a speech launching the American Legion's "Back to God" campaign in 1955. "Without God, there could be no American form of government, nor an American way of life.
In a National Day of Prayer Proclamation, December 5, 1974, President Gerald R. Ford, quoted President Dwight David Eisenhower's 1955 statement: Without God there could be no American form of government, nor an American way of life. Recognition of the Supreme Being is the first - the most basic - expression of Americanism.
