Evangelical Christians are declining:
The most recent Pew Research Center survey of the nation’s religious attitudes, taken in 2012, found that just 19 percent of Americans identified themselves as white evangelical Protestants—five years earlier, 21 percent of Americans did so. Slightly more (19.6 percent) self-identified as unaffiliated with any religion at all, the first time that group has surpassed evangelicals.
Secularization alone is not to blame for this change in American religiosity.
Even half of those Americans who claim no religious affiliation profess belief in God or claim some sort of spiritual orientation. Other faiths, like Islam, perhaps the country’s fastest-growing religion, have had no problem attracting and maintaining worshippers. No, evangelicalism’s dilemma stems more from a change in American Christianity itself, a sense of creeping exhaustion with the popularizing, simplifying impulse evangelical luminaries such as [televangelist Robert] Schuller once rode to success.
Prominent figures in the evangelical establishment have already begun sounding alarms. In particular, the Barna Group, an evangelical market research organization, has been issuing a steady stream of books and white papers documenting the erosion of support for evangelicalism, especially among young people. Contributions from worshippers 55 and older now account for almost two-thirds of evangelical churches’ income in the United States. A mere three percent of non-Christian Americans under 30 have a positive impression of evangelical Christianity, according to David Kinnaman, the Barna Group’s president. That’s down from 25 percent of baby boomers at a similar age. At present rates of attrition, two-thirds of evangelicals in their 20s will abandon church before they turn 30. “It’s the melting of the icebergs,” Kinnaman told me.
