Eileen Lindner, author of a yearbook on American and Canadian churches, says 100,000 Protestant churches in the US will close by 2030. In the 1940's 76 percent of Americans were affiliated with some church, by 2020 that had declined to 47%. The result is a growing number of churches lacking young people. A large number of young people are not affiliated with any church and church attendance dropped during the covid pandemic. NYT looks at what happens when church space is repurposed for restaurants, hotels, theaters, office space, retail space, mixed use developments, affordable housing.
