Episcopal Church leaders have long heard warning sirens in their annual reports, with brutal statistics supporting this reality -- they have lost half of their members since the 1960s.

If trends continue, the mainline Anglican flock in America will lose another half of its membership by 2040, with some demographers predicting institutional demise by 2050. But that's better than the Anglican Church of Canada, which could be gone by 2040.

After years of producing reports about religion in America, political scientist Ryan Burge knows a viral headline when he sees one. One of his recent Graphs about Religion posts asked: "When are Half of Your Members Going to be Dead?"

"Episcopalians are old," wrote Burge. "In fact, two-thirds of their adult members have celebrated their 60th birthday. In contrast, just 6% are under the age of 30. Put simply: for every young adult Episcopalian in the pews this Sunday, there will be about 10 retirees. Oof."

Episcopalians hold five funerals for every wedding, he noted, in a January 23 address for the Episcopal Diocese of Central Florida.

"My job is to tell the truth," said Burge, of the John C. Danforth Center on Religion and Politics at Washington University in St. Louis. For the Episcopal Church, "the check engine light is flashing."

Episcopalians are not alone, he stressed. In the 1950s, according to historians, "mainline" Protestants -- Episcopalians, Lutherans, Presbyterians, Methodists and others -- were 52% of the U.S. population. That fell to 30% by 1970 and, today, has hit 8.7%.

"Guess what? Old people die, and they're really religious. And you know who they're going to be replaced by? Young people, who are not very religious," said Burge, noting that about 43% of Generation Z claims no religious affiliation.

Drawing laughter, he added: "Hey, here's some good news. Attendance is up, a little bit." And donations are steady. However, "If you die with the most money, you're still dead."

Burge's name surfaced during the Episcopal Parish Network's annual meeting, held in Charlotte, North Carolina. Asked about reports of doom, Presiding Bishop Sean Rowe noted that "people make their living telling us that."
