From a Wall Street Journal essay by Ryan Burge headlined “Houses of Worship Shouldn’t Mirror the Class Divide”:

One of the most striking and consequential shifts in U.S. society over the last five decades is the increasing share of Americans who have abandoned religion. In 1972, just 5% of Americans reported that they had no religious affiliation, according to the General Social Survey. In 2021, that number had skyrocketed to nearly 30%. In 2020, the number of Americans who never attend religious services reached 75 million, while the number who attended weekly was 65 million, according to the Cooperative Election Study.
