In 2023, **** percent of Americans were unaffiliated with any religion. A further **** percent of Americans were White evangelical Protestants, and an additional **** percent were White mainline Protestants. Religious trends in the United States Although the United States is still home to the largest number of Christians worldwide, the nation has started to reflect a more diverse religious landscape in recent years. Americans now report a wide range of religious beliefs and backgrounds, in addition to an increasing number of people who are choosing to identify with no religion at all. Studies suggest that many Americans have left their previous religion to instead identify as atheist, agnostic, or nothing in particular, with many reasoning that they stopped believing in the religion's teachings, that they didn't approve of negative teachings or treatment of LGBTQ+ people, or that their family was never that religious growing up. Christian controversies Over the last few years, controversies linked to Christian denominations have plagued the nation, including reports of child sexual abuse by the Catholic Church, the Church of Jesus Christ of Latter-day Saints, and the Southern Baptist Convention. Christian churches have also been accused of supporting discriminatory actions against LGBTQ+ people and people belonging to other religious groups. In addition, there have been increasing concerns about Christian nationalism, the political ideology that asserts that America was founded to be a Christian nation. Although the majority of Americans still think that declaring the United States a Christian nation would go against the U.S. Constitution, studies found that most Republicans would be in favor of this change.

In 2023, about 33 percent of Americans were Protestants, down from 69 percent in 1948. In that same year, about 22 percent of Americans were Catholic, while 22 percent said that they had no religion at all.

The 2008 Conversion Recontact Survey, conducted by the Pew Research Center's Forum on Religion & Public Life, is a follow-up to the 2007 "U.S. Religious Landscape Survey." One of the most striking findings from the Landscape Survey was the large number of people who have left their childhood faith. The Landscape Survey found that more than one in four American adults (28%) have changed their religious affiliation from that in which they were raised. This number includes people who have changed from one major religious tradition to another, for instance, from Protestantism to Catholicism or from Judaism to no religion. If change within religious traditions is included (e.g., from one Protestant denominational family to another), the survey found that roughly 44% of Americans now profess a religious affiliation different from that in which they were raised.

The Conversion Recontact Survey is designed to offer a fuller picture of this churn within American religion, with a special focus on the reasons that people change religious affiliation. The Conversion Recontact Survey is based on follow-up interviews with Landscape Survey respondents, including those from the largest segments of the population that have changed religious affiliation as well as those who still belong to the religious faith in which they were raised. Interviews were conducted by telephone with a nationally representative sample of 2,867 adults living in continental United States telephone households. The survey was conducted by Princeton Survey Research Associates International (PSRAI). Interviews were conducted on landline telephones in English and Spanish by Princeton Data Source (PDS), LLC from Oct. 3 to Nov. 7, 2008. Statistical results are weighted to correct known demographic discrepancies. A full report on the survey's findings, "Faith in Flux: Changes in Religious Affiliation in the U.S.," is available on the Pew Forum's "http://www.pewforum.org/2009/04/27/faith-in-flux/" Target="_blank">website.

This study, designed and completed by the Association of Statisticians of American Religious Bodies (ASARB), represents statistics for 149 religious bodies on the number of congregations within each county of the United States. Where available, also included are actual membership (as defined by the religious body) and total adherents figures. Participants included 149 Christian denominations, associations, or communions (including Latter-day Saints and Unitarian/Universalist groups); two specially defined groups of independent Christian churches; Jewish and Islamic totals; and counts of temples for six Eastern religions.

It is important to understand the methodology producing these data and its limitations. While these data contain membership data for many religious groups in the United States, including most of the larger groups, they do not include every group. It is recommended that users read the notes below. Users may also want to refer to a paper by Roger Finke and Christopher P. Scheitle that explains the "adjusted" adherence rates included in the file.

This study, designed and carried out by the "http://www.asarb.org/" Target="_blank">Association of Statisticians of American Religious Bodies (ASARB), compiled data on 372 religious bodies by county in the United States.

This Pew Research Center survey is a nationally representative sample of U.S. teens and their parents. The data in this nationally representative sample was gathered using a self-administered web survey, and conducted among 1,811 dyads, with each dyad - or pair - comprised of one U.S. adolescent ages 13 to 17 and one parent per adolescent. The findings from this survey are detailed in the following reports, available on the Pew Research Center website: "https://www.pewforum.org/2019/10/03/for-a-lot-of-american-teens-religion-is-a-regular-part-of-the-public-school-day/" Target="_blank">Report 1,"https://www.pewforum.org/2020/09/10/u-s-teens-take-after-their-parents-religiously-attend-services-together-and-enjoy-family-rituals/" Target="_blank">Report 2. In addition to questions on religious practices, beliefs, and identity, this survey also asked teens a series of knowledge questions about the Holocaust, in order to compare adolescents and adults on knowledge of these topics.

The "https://www.pewresearch.org/" Target="_blank">Pew Research Center is a non-partisan organization dedicated to advancing social science research. They research a wide variety of topics through intensive opinion polling and demographic research. In 2014, they conducted a nationally representative telephone survey in the United States called the Religious Landscape Survey. This survey was conducted from June 4 to Sept. 30 in 2014 and featured a sample size of 35,071 U.S. adults. In a continuation of the survey, 5,000 of the respondents from the original poll were contacted again between March 17 and May 6 of 2015 for additional questions.

The survey was conducted on a large scale to develop a more precise understanding of the American religious landscape. The survey was conducted in both Spanish and English with a minimum of 300 interviews per state. The wide net, bilingual nature, and usage of telephones as the main form of communique, allows researchers to estimate that the survey covers 97 percent of non-institutionalized Americans. Though roughly three percent of Americans are not reachable by telephone or do not feature the necessary linguistic skills to participate in the survey, no additional measures were taken to account for this small percentage of the population not represented in the sample.

The large sample size of the research pool allows researchers to take a deeper look into religious groups previously under-studied in smaller surveys. The "https://www.thearda.com/data-archive?fid=RELLAND14" Target="_blank">2014 Religious Landscape study features hundreds of interviews with members of religious groups that make up less than one percent of the American religious sphere. The nature of this survey allows for a nuanced study of religious groups, and their individuals, across the whole of the country.
