Currently, 45 percent of Americans say they belong to a formal house of worship. Similar to the other factors, the percentage of Americans who said they’re members of a church remained stable until relatively recently.
In 1937, 73 percent said they belonged to a church. In 1999, 70 percent said the same. Since then, however, membership numbers have remained below 7 in 10 Americans. The percentage fell below half for the first time in 2020. The current 45 percent is the lowest since Gallup began asking about church membership in 1937.
Gallup reports that the drop has been driven by young adults, more of whom are less likely to identify with a religion. And those who identify with a religion are less likely to be members of a congregation. “But even older adults who have a religious preference are less likely to belong to a church today than in the past.”
