Why the fastest-growing religious group in America is actually not religious at all

In short: The number of Americans reporting no religious affiliation has surged from 2% in 1948 to over 20% today. Yet, these so-called Nones are rarely militant atheists. Most remain spiritual, believe in higher powers, and pray, suggesting that the shift is less about abandoning faith and more about leaving institutions behind.

The rise of the religiously unaffiliated, or Nones, is one of the most significant shifts in American cultural life. While the percentage of Americans identifying as having no religion has climbed steadily—reaching between 22% and 31% in recent estimates—this group is far from a monolith. Researchers like Robert C. Fuller categorize them as 'unchurched' rather than strictly nonreligious. In fact, a 2018 Pew report found that 72% of Nones still hold beliefs in God, a higher power, or spiritual forces. For many, the label indicates a lack of institutional belonging rather than a lack of personal conviction.

This trend is driven by a complex mix of social and generational factors. Younger generations are increasingly distancing themselves from organized religion, often due to a perception that churches are too entangled with conservative politics. Furthermore, broader cultural changes—such as the rise of internet-mediated communities and a shift toward self-focused rather than community-focused citizenry—have weakened loyalty to public institutions across the board. The delay of traditional life milestones like marriage and child-rearing also plays a role, as these events have historically served as entry points into religious participation.

Despite the growth of the Nones, active irreligion remains a niche phenomenon. Only about 1% to 2% of nonreligious Americans join groups that promote secular values. Even those who identify as atheists often exhibit religion-like behaviors, creating communities and debating shared beliefs. Ultimately, the Nones represent a move toward a more individualized, 'spiritual but not religious' landscape. While they now constitute the largest 'religious' voting block in the country—with over six-in-ten leaning toward the Democratic Party—their collective identity remains defined more by indifference toward traditional structures than by a cohesive, organized rejection of the divine.
