When it came to poll numbers about religion and American life, the late George Gallup, Jr., wasn’t all that interested in many of the most obvious questions.
As he told me in several telephone interviews, starting in the 1980s: The religion numbers just don’t add up. You could see the same sentiments in some of his public addresses.
Gallup — who died in 2011 — wasn’t impressed by the high numbers of Americans who told pollsters that they believe in God, attend worship services on a regular basis and say that faith is “very important” in their lives. That didn’t seem to fit with national patterns of divorce and family breakdown. He kept trying to find ways to ask questions that focused on the role of religious faith in daily life.
When push came to shove, Gallup was convinced that about 20% of Americans were seriously practicing some form of religious faith. The number might be lower than that.
Thus, that recent blitz of news about church membership trends. As the Washington Post headline stated: “Church membership in the U.S. has fallen below the majority for the first time in nearly a century.” Here’s some of the overture:
The proportion of Americans who consider themselves members of a church, synagogue or mosque has dropped below 50 percent, according to a poll from Gallup. … It is the first time that has happened since Gallup first asked the question in 1937, when church membership was 73 percent. …
In 2020, 47 percent of Americans said they belonged to a church, synagogue or mosque. The polling firm also found that the number of people who said religion was very important to them has fallen to 48 percent, a new low point in the polling since 2000.

Gallup asks Americans a battery of questions on their religious attitudes and practices twice each year. The following analysis of declines in church membership relies on three-year aggregates from 1998-2000 (when church membership averaged 69%), 2008-2010 (62%), and 2018-2020 (49%). …
The decline in church membership is primarily a function of the increasing number of Americans who express no religious preference.
