The visualization reimagines the U.S. religious landscape as a group of 100 people.
Each person represents roughly 1% of U.S. adults. Totals may not sum to exactly 100 due to rounding in survey responses. The data for this visualization comes from Pew Research Center’s 2023–24 Religious Landscape Study.
Christianity Remains the Largest Bloc, but It’s Diverse
Christians make up about six in ten U.S. adults in this snapshot, yet the bloc spans multiple traditions with distinct histories, geographies, and growth patterns.
Evangelical Protestants are the single largest subgroup at nearly one quarter of the “100 people,” while Catholics account for just under one-fifth. Mainline and Historically Black Protestant traditions together represent 16 people, underscoring Protestantism’s internal variety.
The two “Other Christian” people reflect communities often missed in headline figures, from Eastern Orthodoxy to millenarian groups.

| Black Protestant | 5 | |

| LDS (Mormon) | 2 | |
| Other Christian | 2 | |
| Non-Christian (7) | Jewish | 2 |
| Muslim | 1 | |
| Hindu | 1 | |
| Buddhist | 1 | |
| Other religions | 2 | |
| Unaffiliated (29) | — | 29 |
The Rise of the Religiously Unaffiliated
Nearly three in ten people in the group report no religious affiliation. This segment includes atheists, agnostics, and those who describe their religion as “nothing in particular.”
In absolute terms, that’s about 76 million U.S. adults that have no religious affiliation.
America’s Religious Pluralism Beyond Christianity
Seven of the 100 people belong to non-Christian religions: roughly two Jewish, and about one each Muslim, Hindu, and Buddhist, plus two in other faiths.
While small in share, these communities are often concentrated in specific regions and metro areas, shaping local culture and institutions. Immigration patterns, birth rates, and conversion dynamics help explain their distribution and growth trends.
