In 2020, around 28.8 percent of the global population were identified as Christian. Around 25.6 percent of the global population identify as Muslims, followed by 14.9 percent of global populations as Hindu. The number of Muslims increased by 347 million, when compared to 2010 data, more than all other religions combined.

The statistic shows the religious affiliation of the population in the United States in 2017, by age. In 2017, about 38 percent of respondents aged 18 to 29 years old were unaffiliated with any religious belief.

The World Religion Project (WRP) aims to provide detailed information about religious adherence worldwide since 1945. It contains data about the number of adherents by religion in each of the states in the international system. These numbers are given for every half-decade period (1945, 1950, etc., through 2010). Percentages of the states' populations that practice a given religion are also provided. (Note: These percentages are expressed as decimals, ranging from 0 to 1, where 0 indicates that 0 percent of the population practices a given religion and 1 indicates that 100 percent of the population practices that religion.) Some of the religions are divided into religious families. To the extent data are available, the breakdown of adherents within a given religion into religious families is also provided.

The project was developed in three stages. The first stage consisted of the formation of a religion tree. A religion tree is a systematic classification of major religions and of religious families within those major religions. To develop the religion tree we prepared a comprehensive literature review, the aim of which was (i) to define a religion, (ii) to find tangible indicators of a given religion of religious families within a major religion, and (iii) to identify existing efforts at classifying world religions. (Please see the original survey instrument to view the structure of the religion tree.) The second stage consisted of the identification of major data sources of religious adherence and the collection of data from these sources according to the religion tree classification. This created a dataset that included multiple records for some states for a given point in time. It also contained multiple missing data for specific states, specific time periods and specific religions. The third stage consisted of cleaning the data, reconciling discrepancies of information from different sources and imputing data for the missing cases.

The National Religion Dataset: The observation in this dataset is a state-five-year unit. This dataset provides information regarding the number of adherents by religions, as well as the percentage of the state's population practicing a given religion.

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. Of these, the ASARB was able to gather data on congregations and adherents for 217 religious bodies and on congregations only for 155. Participating bodies included 354 Christian denominations, associations, or communions (including Latter-day Saints, Messianic Jews, and Unitarian/Universalist groups); counts of Jain, Shinto, Sikh, Tao, Zoroastrian, American Ethical Union, and National Spiritualist Association congregations, and counts of congregations and adherents from Baha'i, three Buddhist groupings, two Hindu groupings, and four Jewish groupings, and Muslims. The 372 groups reported a total of 356,642 congregations with 161,224,088 adherents, comprising 48.6 percent of the total U.S. population of 331,449,281. Membership totals were estimated for some religious groups.

In January 2024, the ARDA added 21 religious tradition (RELTRAD) variables to this dataset. These variables start at variable #8 (TOTCNG_2020). Categories were assigned based on pages 88-94 in the original "https://www.usreligioncensus.org/index.php/node/1638" Target="_blank">2020 U.S. Religion Census Report.

About this dataset

Context

The dataset tabulates the Faith population distribution across 18 age groups. It lists the population in each age group along with the percentage population relative of the total population for Faith. The dataset can be utilized to understand the population distribution of Faith by age. For example, using this dataset, we can identify the largest age group in Faith.

Key observations

The largest age group in Faith, SD was for the group of age 60 to 64 years years with a population of 44 (13.46%), according to the ACS 2019-2023 5-Year Estimates. At the same time, the smallest age group in Faith, SD was the Under 5 years years with a population of 0 (0%). Source: U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates

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.

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 RCS-Dem dataset reports estimates of religious demographics, both country by country and region by region. RCS was created to fulfill the unmet need for a dataset on the religious dimensions of countries of the world, with the state-year as the unit of observation. It covers 220 independent states, 26 selected substate entities, and 41 geographically separated dependencies, for every year from 2015 back to 1900 and often 1800 (more than 42,000 state-years). It estimates populations and percentages of adherents of 100 religious denominations including second level subdivisions within Christianity and Islam, along with several complex categories such as "Western Christianity." RCS is designed for easy merger with datasets of the Correlates of War and Polity projects, datasets by the United Nations, the Religion And State datasets by Jonathan Fox, and the ARDA national profiles.

The Religious Characteristics of States Dataset (RCS) was created to fulfill the unmet need for a dataset on the religious dimensions of countries of the world, with the state-year as the unit of observation. The third phase, Chief Executives' Religions, provides data on religious affiliations of countries' 'chief executives,' i.e., their presidents, prime ministers, or other heads of state/government exercising largely real, not ceremonial, political power. The dataset, like others in the RCS data project, is designed expressly for easy merger with datasets of the Correlates of War and Polity projects, datasets by the United Nations, the Religion And State datasets by Jonathan Fox, and the ARDA national profiles.

This is the replication package for "Churches as Social Insurance: Oil Risk and Religion in the U.S. South". Abstract: Religious communities are important providers of social insurance. We show that risk associated with oil dependence facilitated the proliferation of religious communities throughout the U.S. South during the 20th century. Known oil abundance predicts higher rates of church membership, which are not driven by selective migration or local economic development. Consistent with a social insurance channel, greater oil price volatility increases effects, while greater access to credit, state-level social insurance, and private insurance crowds out effects. Religious communities limit spillovers of oil price shocks across sectors, reducing increases in unemployment following a negative shock by about 30%.

This statistic shows the giving levels across congregations in the United States in 2008, by faith tradition. As of 2008, about 11 percent of Catholic adherents give 10 percent or more of their net income regularly to church.
