Gallup, June 26, 2023:
U.S. church attendance has shown a small but noticeable decline compared with what it was before the COVID-19 pandemic. In the four years before the pandemic, 2016 through 2019, an average of 34% of U.S. adults said they had attended church, synagogue, mosque or temple in the past seven days. From 2020 to the present, the average has been 30%, including a 31% reading in a May 1-24 survey.
The recent church attendance levels are about 10 percentage points lower than what Gallup measured in 2012 and most prior years.
