28% of U.S. adults are religiously unaffiliated, describing themselves as atheists, agnostics or “nothing in particular” when asked about their religion.
Although it’s possible that the “nones” have leveled off, it’s also possible that their growth has continued, but at a gradual pace that is difficult to see in the data.
Overall, 70% of U.S. adults describe themselves as spiritual in some way, including 22% who are spiritual but not religious. An overwhelming majority of U.S. adults (83%) say they believe that people have a soul or spirit in addition to their physical body. And 81% say there is something spiritual beyond the natural world, even if we cannot see it.
Based on formal religious identity, China is the least religious country in the world – with just 10% of Chinese adults self-identifying with a religion.
Only one-in-ten Chinese adults formally identify with a religion, but surveys indicate that religion plays a much bigger role in China when the definition is widened to include questions on spirituality, customs and traditional beliefs.
Most U.S. adults – including a solid majority of Christians and large numbers of people who identify with other religious traditions – consider the Earth sacred and believe God gave humans a duty to care for it. But highly religious Americans are far less likely than other U.S. adults to express concern about warming temperatures around the globe.
