The term religious nones refers to the roughly 28 percent of American adults who identify as atheist, agnostic, or nothing in particular when surveyed about faith. Rising from single digits in the late twentieth century, this diverse cohort represents a major transformation in how millions approach spiritual life, personal morality, and organized religious institutions.
Who Are the Religious Nones? The Three Distinct Groups
The label "nones" originated among sociologists reading survey questionnaires where respondents selected the option for "none" under religious affiliation. While popular media often characterizes this segment as uniformly secular or non-believing, research reveals three distinct groups within the broader category of unaffiliated Americans:
- Nothing in Particular (roughly 63 percent of nones): Representing about 18 to 19 percent of all American adults, this is by far the largest group of unaffiliated individuals. Most are not philosophical materialists or anti-religious activists. Rather, they simply do not prioritize institutional religious practice, hold loosely defined personal beliefs, or feel disconnected from formal denominational traditions.
- Agnostics (roughly 20 percent of nones): Comprising approximately 5 percent of the national adult population, agnostics believe that the existence of God, the divine, or the supernatural is unknown or inherently unknowable. They tend to exhibit higher levels of education and frequently emphasize scientific inquiry, empirical verification, and open-ended skepticism.
- Atheists (roughly 17 percent of nones): Making up about 4 percent of all American adults, atheists actively reject belief in God or a higher power. They are typically the most secular and civically vocal subset of the nones, strongly advocating for church-state separation and rationalist philosophy in public policy.
Understanding these distinctions is essential for analyzing the nones religion phenomenon. The vast majority of unaffiliated citizens are not committed secularists, but individuals who have drifted away from institutional loyalty while retaining varied spiritual instincts.
Tracking the Growth: From the 1990s to the Recent Plateau
The emergence of religious nones as a major demographic bloc occurred with remarkable speed. According to the General Social Survey (GSS), conducted by NORC at the University of Chicago, the proportion of Americans claiming no religion remained stable between 5 and 8 percent throughout the 1970s and 1980s. Sociologists widely regarded the United States as a global exceptio— wealthy, modernized nation that remained intensely religious throughout its industrial and post-industrial expansion.
That began to change dramatically during the 1990s. By 2000, GSS data recorded nones at roughly 14 percent. A landmark 2007 Pew Research Center survey found the unaffiliated share had reached 16 percent, climbing to 23 percent in the 2014 Religious Landscape Study. By 2023, Pew reported that 28 percent of American adults identified as nones, matching or exceeding the share of Catholics or evangelical Protestants in the national population.
However, recent measurements indicate that the rapid expansion of the nones has entered a period of stabilization. Between 2018 and 2023, the national percentage of unaffiliated adults hovered consistently between 27 and 29 percent. This plateau suggests that while secularization has reshaped the cultural baseline, the rapid generational erosion witnessed over the previous three decades is moderating into a steady equilibrium, where committed believers and secular individuals coexist in predictable proportions.
Demographics: Age, Geography, and Political Perspectives
The presence of unaffiliated Americans is not uniform across society; it varies dramatically according to age, region, and political orientation.
Age remains the single most powerful predictor of religious affiliation. According to Pew Research Center studies published in 2024, approximately 40 percent of adults under age 30 identify as nones, compared to only 17 percent of adults aged 65 and older. Because each emerging generation enters adulthood significantly less attached to churches than its predecessors, generational replacement continues to maintain high secular numbers even as older, highly observant generations pass away.
Geographically, the nones are concentrated most heavily in the Pacific Northwest and New England. In states like Oregon, Washington, Vermont, and New Hampshire, more than 30 to 35 percent of residents claim no religion. In contrast, the American South retains much higher rates of traditional adherence, though urban centers across Texas, Georgia, and North Carolina have seen nones expand rapidly. This geographic divide mirrors the regional patterns observed in our analysis of how many churches are in the US.
Politically, nones lean significantly toward the Democratic Party and liberal social viewpoints, especially on issues such as environmental policy, marriage equality, and reproductive rights. However, important internal differences exist. While atheists and agnostics vote at high rates and lean heavily progressive, those describing their religion as "nothing in particular" are among the least politically engaged demographic groups in the nation, frequently registering low voter turnout and expressing deep distrust of political and religious institutions alike.
Spiritual but Not Religious: Beliefs Without Formal Creed
One of the most surprising findings about religious nones is that the majority are not completely secular. In a comprehensive 2024 Pew survey examining the beliefs of the unaffiliated, nearly 70 percent of nones stated that they believe in God or another higher spiritual power. Only 29 percent claimed to reject belief in any higher power whatsoever.
Furthermore, approximately half of all nones describe themselves as "spiritual" or say that spirituality is an important dimension of their lives. Many engage in personal spiritual practices, including meditation, spending contemplative time in nature, and expressing reverence for the universe. Substantial numbers report belief in an afterlife, the human soul, and unseen spiritual energy, even as they decline to participate in organized religious liturgies or affirm historic theological dogmas.
When asked why they do not belong to a church, nones rarely cite philosophical atheism. Instead, the most common reasons include doubts about religious teachings, dislike of organized religious hierarchies, and frustration with church involvement in partisan politics. For many, formal religion feels rigid or judgmental, prompting them to construct individualized spiritual frameworks outside conventional church walls.
Will the Nones Return to Church as They Age?
For decades, church leaders comforted themselves with the belief that young, unchurched adults would return to congregations once they married, purchased homes, and began raising children. Historically, this life-cycle pattern functioned reliably throughout the twentieth century, as young parents sought moral guidance, Sunday schools, and community support for their growing families.
Sociological data from the past two decades demonstrates that this pattern has largely broken down. Studies tracking cohorts over time show that millennials and older members of Generation Z are not returning to church at anywhere near the rates of previous generations. Longitudinal surveys indicate that roughly 80 percent of Americans who enter adulthood as nones remain unaffiliated as they mature, marry, and raise children.
Because these young adults were frequently raised by parents who had already loosened their ties to church life, they have little nostalgia for traditional liturgical rhythms. Rather than seeking out baptism or church youth programs, unaffiliated parents increasingly rely on public schools, community youth sports, and secular neighborhood organizations for social connection and moral formation.
What the Rise of the Nones Means for American Congregations
The expansion of the nones has sent ripple effects throughout the institutional religious world, fundamentally altering community dynamics across the nation. The decline in prospective churchgoers has contributed directly to the broader trends documented in our study of church attendance in America.
Historic mainline bodies have felt this pressure most acutely, experiencing decades of shrinking rolls explored in our analysis of the decline of mainline Protestantism. As generational replacement diminishes membership, thousands of congregations face financial strains and property sales detailed in our review of why churches are closing in America. Even rural areas, once considered insulated from secular trends, now experience declining youth participation, as documented in our study of rural churches in America.
Yet the rise of the nones has also prompted creative adaptation. Independent church planting movements within the fastest-growing denominations in America have reimagined worship gatherings, adopting casual meeting spaces, modern musical styles, and practical community service initiatives designed specifically to connect with unchurched neighbors. Furthermore, suburban megachurches in America have developed broad recreational and family programs to lower barriers for unaffiliated seekers. Simultaneously, active Hispanic churches in America and diverse immigrant churches in America continue to demonstrate strong retention and evangelistic vitality, providing an alternative trajectory to native secularization.
In the evolving American religious environment, congregations can no longer rely on automatic cultural respect or default social participation. Instead, churches must actively articulate their value, cultivate authentic human relationships, and demonstrate tangible love within the communities they serve.
