According to a 2022 survey, 31 percent of Americans never attend church or synagogue, compared to 20 percent of Americans who attend every week.

Religiosity in the United States

Despite only about a fifth of Americans attending church or synagogue on a weekly basis, almost 40 percent consider themselves to be very religious. Additionally, states in the Deep South such as Mississippi, Alabama, and Louisiana had the most residents identifying as very religious. In contrast, New England states like Vermont, Maine, and New Hampshire had the most people identifying as nonreligious.

A Christian nation?

Despite the official separation of church and state embedded in the Constitution, many would still consider the United States to be a Christian nation. Catholicism has the largest number of adherents in the United States, due to there being many different Protestant denominations. The Southern Baptist Convention had the largest number of Evangelical adherents, while the United Methodist Church was the largest Mainline Protestant denomination.

The share of Americans who were not a member of a church or synagogue has been increasing since 1992. In 2023, about 55 percent of Americans were not members of a church or synagogue. In that same year, 45 percent of Americans were members of a church or synagogue.

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, 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 #12 (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.

Belief in God has historically been a persistent aspect of American society, with 96 percent of surveyed Americans saying that they believed in God in 1944. However, the share of Americans who believed in God has decreased steadily over time after reaching a peak of 98 percent in the 1950s and 60s. As of 2022, the share of Americans who believed in God had fallen to 81 percent. Religious participation and practice There has been a significant reduction in participation within religious organizations in the United States, with Americans found less likely to attend church or become members of a church. While 70 percent of Americans belonged to a church, synagogue, mosque, or temple in 1999, this number dropped to 47 percent by 2021. This decline in church membership may have contributed to Americans’ waning belief in God, as continuous religious practice has been attributed to greater faith and religious conviction. 74 percent of Americans who attended religious services weekly believed that God hears prayers and intervenes, in comparison to 28 percent of Americans who seldom or never attended religious services. Younger Americans less likely to believe While most U.S. adults still believe in God, younger Americans are less likely to share this belief. Older generations of Americans were more likely to participate in religious services while growing up, with 68 percent of the Silent Generation reporting that they attended Sunday school or another religious education program, while Generation Z were more likely to have lacked any sort of religious upbringing in the United States. In 2021, 15 percent of Gen Z said that they had never been religious.

The Statistics of Churches in the United States was part of the 11th Census, conducted in 1890 (the U.S. Census collected data on religion through the 1936 census, though the 1890 Census was the first to count the number of members). The Census collected data on church seating capacity, property value, number of members, number of edifices ("buildings owned and used for worship"), and number of organizations (churches, mission stations when separate from congregation, chapels when they are separate from churches, and societies or meetings among groups that designate such organizations). The data are organized by counties (counties are the cases). Measures for religions in Indian Territories are also included.

This dataset is a longitudinal version of the Churches and Church Membership in the United States studies from 1980 and 1990, and the Religious Congregations and Membership Studies from 2000 and 2010. It contains the adherent and congregation counts of 302 religious groups that participated in at least one of the 1980-2010 data collections. It is very important to understand how this file differs from its standalone counterparts, and its many limitations. Using these data for over-time comparisons without reading any documentation will likely result in inaccurate statistics. Data users are strongly urged to read the paper by Rachel Bacon, Roger Finke and Dale Jones that details all the changes made when creating the longitudinal file. Major changes made to the file include new variable naming schemes, new combined religious groups that correct for schisms and mergers, new adherent counts for the United Methodist Church, and count estimates for missing data among 40 groups.
