Protestant churches are losing young adults in "sobering" numbers, a survey finds.
Seven in 10 Protestants ages 18 to 30 — both evangelical and mainline — who went to church regularly in high school said they quit attending by age 23, according to the survey by LifeWay Research. And 34% of those said they had not returned, even sporadically, by age 30. That means about one in four Protestant young people have left the church.
