Christians remain by far the largest religious group in the United States, but the Christian share of the population has declined markedly. In the by seven years, the percentage of adults who describe themselves as Christians has dropped from 78.4% to lxx.6%.

In one case an overwhelmingly Protestant nation, the U.Southward. no longer has a Protestant majority. In 2007, when the Pew Research Center conducted its first Religious Mural Study, more than than one-half of adults (51.three%) identified every bit Protestants. Today, by comparison, 46.5% of adults depict themselves equally Protestants.

While there have been declines across a multifariousness of Protestant denominations, the almost pronounced changes have occurred in churches in the mainline Protestant tradition, such as the United Methodist Church building and the Evangelical Lutheran Church in America. The share of adults belonging to mainline churches dropped from 18.1% in 2007 to 14.vii% in 2014. This is similar to the drop seen amongst U.S. Catholics, whose share of the population declined from 23.9% to 20.8% during the same seven-year period.

In contrast with mainline Protestantism, in that location has been less change in recent years in the proportion of the population that belongs to churches in the evangelical or historically black Protestant traditions. Evangelicals at present brand upwardly a articulate bulk (55%) of all U.South. Protestants. In 2007, 51% of U.S. Protestants identified with evangelical churches.

While the overall Christian share of the population has dropped in contempo years, the number of Americans who do not identify with whatever faith has soared. Nearly 23% of all U.S. adults at present say they are religiously unaffiliated, upward from about 16% in 2007. While most of the unaffiliated draw themselves every bit having "no particular religion," a growing share say they are atheists or agnostics.

This affiliate takes a close wait at the electric current religious limerick of the The states and how it has inverse since 2007. A full-page table (PDF) summarizes the religious affiliation of U.Southward. adults in a fashion that captures small groups that make up less than 1% of the population.

The affiliate also explains how Protestant respondents were sorted into the three singled-out Protestant traditions – the evangelical Protestant tradition, the mainline Protestant tradition and the historically black Protestant tradition – and it documents which Protestant denominations are shrinking, and which are growing.

Finally, the chapter examines the growth of non-Christian religions in the U.Due south. and takes a closer expect at the composition of the religiously unaffiliated population.

Measuring and Categorizing Protestantism

American Protestantism is diverse, encompassing more than a dozen major denominational families – such as Baptists, Methodists, Lutherans and Pentecostals – all with unique behavior, practices and histories. These denominational families, in turn, are made up of a host of different denominations, such as the Southern Baptist Convention, the American Baptist Churches The states and the National Baptist Convention.

Denominations: The term "denomination" refers to a set of congregations that belong to a unmarried administrative structure characterized by particular doctrines and practices. Examples of denominations include the Southern Baptist Convention, the American Baptist Churches Usa and the National Baptist Convention.

Families: A denominational family is a set of religious denominations and related congregations with a common historical origin. Examples of families include Baptists, Methodists and Lutherans. Most denominational families consist of denominations that are associated with more than one of the three Protestant traditions. The Baptist family, for instance, consists of some denominations that autumn into the evangelical tradition, others that belong to the mainline tradition and yet others that are role of the historically black Protestant tradition.

Traditions: A religious tradition is a fix of denominations and congregations with similar behavior, practices and origins. In this report, Protestant denominations are grouped into three traditions: the evangelical tradition, the mainline tradition and the historically black Protestant tradition.

Because of this not bad diversity, American Protestantism is best understood not as a single religious tradition but rather equally 3 distinct traditions – the evangelical Protestant tradition, the mainline Protestant tradition and the historically black Protestant tradition. Each of these traditions is made up of numerous denominations and congregations that share similar behavior, practices and histories.

For instance, churches within the evangelical tradition tend to share religious beliefs (including the confidence that personal acceptance of Jesus Christ is the only mode to salvation), practices (like an accent on bringing other people to the religion) and origins (including separatist movements against established religious institutions). Churches in the mainline tradition, by contrast, share other doctrines (such every bit a less exclusionary view of salvation), practices (such equally a potent emphasis on social reform) and origins. Churches in the historically black Protestant tradition take been shaped uniquely past the experiences of slavery and segregation, which put their religious beliefs and practices in a special context.

Protestant Denominational Families Include Denominations Associated With Different Traditions Equally much as possible, Protestant respondents were categorized into one of the three Protestant traditions based not on their denominational family, but rather on the specific denomination with which they identify. Almost Protestant denominational families include denominations that are associated with unlike Protestant traditions. For example, some Baptist denominations (like the Southern Baptist Convention) are function of the evangelical tradition; others (such as the American Baptist Churches United states) are role of the mainline tradition; and however others (such as the National Baptist Convention) are part of the historically black Protestant tradition.

Overall, threescore% of Baptists in the survey identify with denominations in the evangelical tradition; 14% associate with denominations in the mainline Protestant tradition, and 26% place with denominations that are part of the historically blackness Protestant tradition. (While the Baptist family of denominations includes churches in all three Protestant traditions, this is not the example for all denominational families, some of which have members in only ane or ii of the Protestant traditions.)

Despite the detailed denominational measures used in the Religious Landscape Study, many respondents (more than a quarter of all Protestants) were either unable or unwilling to describe their specific denominational affiliation. For instance, some respondents draw themselves as "but a Baptist" or "just a Methodist." Respondents with this type of vague denominational amalgamation were sorted into one of the three Protestant traditions in 2 ways.13

First, blacks who gave vague denominational affiliations (e.yard., "simply a Methodist") but who said they belong to a Protestant family with a sizable number of historically black churches (including the Baptist, Methodist, nondenominational, Pentecostal and Holiness families) were coded as members of the historically black Protestant tradition. Black respondents in denominational families without a sizable number of churches in the historically blackness Protestant tradition were coded as members of the evangelical or mainline Protestant traditions depending on their response to a separate question asking whether they would place equally a born-once more or evangelical Christian.

2nd, not-black respondents who gave vague denominational identities and who described themselves every bit born-over again or evangelical Christians were coded every bit members of the evangelical tradition; otherwise, they were coded equally members of the mainline tradition.fourteen

Overall, 38% of Protestants offered a vague denominational identity and thus were classified on the ground of their race and/or their respond to the question about whether they place as a built-in-again or evangelical Christian. This includes 36% of those in the evangelical tradition, 35% of those in the mainline tradition and 53% of those in the historically black Protestant tradition.

The Shifting Limerick of American Protestantism

Contempo years have brought a dramatic decline in the share of Americans who identify with mainline Protestant denominations. Today, just fifteen% of all U.South. adults identify with mainline Protestant churches, down from 18% in 2007. By comparison, evangelical Protestantism and the historically black Protestant tradition have been more stable. Today, 25% of U.South. adults identify with evangelical denominations, downwardly less than one percent bespeak since 2007. And roughly 7% of American adults identify with the historically black Protestant tradition, little changed since 2007.

The mainline tradition'southward share of the Protestant population has declined along with its share of the overall population. Today, 32% of Protestants identify with denominations in the mainline tradition, downwards from 35% in 2007. Evangelicals now establish a clear bulk of all Protestants in the U.Due south., with their share of the Protestant population having risen from 51% in 2007 to 55% in 2014.

Biggest Declines Seen Among Mainline Protestants

Many Protestant denominational families have seen their share of the U.Southward. population fall since 2007. Baptists now account for approximately 15% of the developed population, down from 17% in 2007. Methodists and Lutherans also accept declined by more than than a full percentage point in recent years. The family that shows the most significant growth is the nondenominational family; today, half-dozen.2% of all adults (and 13% of Protestants) identify with nondenominational churches, up from 4.5% of all adults (and 9% of all Protestants) in 2007.

Nondenominational Share of the Protestant Population Grows

The Southern Baptist Convention (an evangelical denomination) and the United Methodist Church (a mainline denomination) continue to be the two largest Protestant denominations in the U.S.; 11% of Protestants identify with the Southern Baptist Convention and 8% identify with the United Methodist Church. Both denominations, still, have experienced declines in their relative share of the population. In the 2014 Religious Landscape Study, 5.3% of all U.South. adults identify with the Southern Baptist Convention (down from half-dozen.7% in 2007) and 3.6% identify with the United Methodist Church (downward from 5.1% in 2007).

Fifteen Largest Protestant Denominations

Growth of Non-Christian Faiths

Growing Minority Identifies With Faiths Other Than Christianity The 2014 Religious Mural Written report finds that 5.ix% of U.Due south. adults identify with faiths other than Christianity, upward slightly, but significantly, from 4.7% in 2007. The largest of these faiths is Judaism, with 1.9% of respondents identifying themselves equally Jewish when asked about their faith. Amongst Jews surveyed, 44% identify with Reform Judaism, 22% with Conservative Judaism, 14% with Orthodox Judaism, 5% with other Jewish movements and sixteen% with no particular Jewish denomination. These findings are broadly like to results from the Pew Research Center's 2013 survey of Jewish Americans.xv

Muslims (0.nine%), Buddhists (0.7%) and Hindus (0.vii%) each make upwards slightly less than 1% of respondents in the 2014 Religious Landscape Written report. The Muslim and Hindu shares of the population have risen significantly since 2007. And it is possible, even despite this growth, that the Religious Landscape Study may underestimate the size of these groups. The written report was conducted in English and Spanish, which means that groups with above-average numbers of people who do not speak English language or Spanish (such every bit immigrants from Asia, Africa and other parts of the world) may be underrepresented. For instance, an assay of the Pew Research Center'south 2012 survey of Asian Americans (conducted in English, Cantonese, Hindi, Japanese, Korean, Mandarin, Tagalog and Vietnamese) estimated that Buddhists account for betwixt 1.0% and 1.3% of the U.S. adult population, and that Hindus business relationship for between 0.5% and 0.8% of the population. The Pew Research Centre's 2007 and 2011 surveys of Muslim Americans (conducted in English, Standard arabic, Persian and Urdu) estimated that Muslims accounted for 0.six% of the adult population in 2007 and 0.8% in 2011.

The 2014 Religious Landscape Study finds that 0.3% of American adults identify with a wide variety of other world religions, including Sikhs, Baha'is, Taoists, Jains, Rastafarians, Zoroastrians, Confucians and Druze. An boosted 1.5% identify with other faiths, including Unitarians, those who place with Native American religions, Pagans, Wiccans, New Agers, deists, Scientologists, pantheists, polytheists, Satanists and Druids, to name only a few.

Composition of the Religious The religiously unaffiliated population – including all of its constituent subgroups – has grown apace every bit a share of the overall U.South. population. The share of self-identified atheists has nearly doubled in size since 2007, from one.6% to 3.1%. Agnostics have grown from ii.4% to 4.0%. And those who describe their religion as "null in particular" take swelled from 12.ane% to xv.8% of the adult population since 2007. Overall, the religious "nones" take grown from 16.ane% to 22.viii% of the population in the past seven years.

Equally the unaffiliated have grown, the internal limerick of the religious "nones" has changed. Near unaffiliated people continue to describe themselves as having no particular religion (rather than every bit beingness atheists or agnostics), but the "nones" appear to exist growing more secular. Atheists and agnostics now business relationship for 31% of all religious "nones," upward from 25% in 2007.

Meanwhile, the share of the "nones" describing their religion as "nada in particular" has declined from 75% in 2007 to 69% in 2014. And this turn down is particularly notable among those who say religion is "very" or "somewhat" important in their lives despite eschewing whatsoever identification with a particular religion. Those who describe their religion every bit "nada in item" and who also say that religion is of import in their lives now account for 30% of all religious "nones," downwards from 36% in 2007. Those who describe their religion as "null in particular" and furthermore state that religion is unimportant in their lives account for 39% of all religious "nones," the same share every bit 2007.

A Note on How the Study Defines Evangelicals

How many Americans are evangelical Christians? The answer depends on how evangelicalism is being defined.

More Than a Third of U.S. Adults Describe Themselves as Born-Again or Evangelical ChristiansThere are a number of means this can exist washed. The approach taken in the 2014 Religious Landscape Report, for case, focuses just on Protestants. It looks at the denominations and congregations with which Protestants identify, and determines whether these denominations and congregations are part of the evangelical Protestant tradition, mainline Protestant tradition or historically black Protestant tradition. Those who belong to denominations and churches that are office of the evangelical Protestant tradition (such equally the Southern Baptist Convention, the Assemblies of God and many nondenominational churches) are categorized equally evangelical Protestants in the study; those who belong to denominations or churches in the other two Protestant traditions are not. Using this approach, the study finds that 25.4% of U.S. adults are evangelical Protestants, down from 26.three% in 2007, when the first Religious Landscape Study was conducted.

Another way to place evangelicals is to enquire people whether they consider themselves evangelical or born-once again Christians. The Religious Mural Study includes a question asking Christians: "Would yous draw yourself as a born-once again or evangelical Christian, or not?" In response to this question, one-half of Christians (35% of all U.S. adults) say yes, they do consider themselves born-again or evangelical Christians. The share of self-described built-in-again or evangelical Christians is very like to what it was in 2007, even though the overall Christian share of the population has declined.

Most in Evangelical, Historically Black Protestant Traditions Identify as Born-Again or Evangelical Not surprisingly, near members of the evangelical Protestant tradition (83%) run into themselves as born-again or evangelical Christians, as practise nearly members of the historically black Protestant tradition (72%) and a sizable minority of people in the mainline Protestant tradition (27%). Many Christians who do non place with Protestantism also consider themselves born-over again or evangelical Christians, including 22% of Catholics, 18% of Orthodox Christians, 23% of Mormons and 24% of Jehovah'south Witnesses.

Three-in-Ten U.S. Adults Are Born-Again or Evangelical ProtestantsWhen Catholics, Mormons and other not-Protestants are excluded, the written report finds that three-in-x U.S. adults are cocky-described born-again or evangelical Protestants. Although the percentage of Americans who place as Protestants has declined in recent years (from 51% in 2007 to 47% today), the share of born-again or evangelical Protestants has remained the same.

White built-in-again or evangelical Protestants – a group closely watched past political observers – now business relationship for 19% of the adult population, down slightly from 21% in 2007. Over that period of time, the white share of respondents fell from 71% in the 2007 Religious Mural Study to 66% in 2014.
Another way to define evangelical Protestants is to identify a set of religious beliefs or practices that are central to evangelicalism, and then assess how many people profess those beliefs or engage in those practices. When measured this way, the size of the evangelical population depends on the detail behavior and practices that are used to define the category. While this type of analysis is beyond the scope of the Religious Landscape Study, a forthcoming report will examine the beliefs and practices of major religious groups and their views on social and political issues.
