Every major wing of American Christianity declined just in this latest six-year period. To make matters worse, these were the alarming vital signs well before the COVID-19 tsunami. By all accounts, church involvement has plummeted enormously since Spring 2020, and will struggle to revive to even close to these dismal 2019 levels. The only question is how much steeper the ongoing decline will be because of the pandemic, not whether there will be one.
When I visit my family physician, he starts by checking my vitals. It’s amazing how critical are simple things like blood pressure, temperature, and pulse.
We social scientists know that vital signs matter in organized religion, too. There are a lot of details we can look at, but basics such as how many people identify with churches, whether they attend services regularly, or apply their faith to their daily lives, are awful important. Here is what we know: the vital signs of American Christianity are in serious decline.
Recently, I compared crucial vital signs for Americans aged 18 to 44, surveyed in the respected National Survey of Family Growth (NSFG). I compared the data released in 2013 to the same survey released just six years later, in 2019. Here’s what the data show:
For both males and females, membership in Evangelical Protestant, Mainline Protestant, and historically Black Protestant churches declined a lot. Meanwhile, those professing no religious faith—called “Nones” in sociological circles—rose sharply: from 26% to 38% among males, and from 22% to 28% among females. Within each of these three divisions of Protestantism, the percentages of both males and females who reported attending church every week or more declined quite a bit, while those who attended rarely or never increased. The percentages of both males and females who claimed that their faith is “very important” in their daily lives also sank in each of these Protestant groups.
Mainline Protestantism, especially, is on life support. In this survey and age group, the numbers went down one-fifth, and were only 12% in the latest NSFG. Among mainliners, only 20% of males and 28% of females went to church every week, 28% of males and 18% of females said they that they never go to church, and only 28% of males and 40% of females considered their faith to be very important. Optimistically, this means that less than 5% of Americans from 18-to-44 are actively committed to a Mainline Protestant church.
This is a double decline whammy. The numbers are dropping, and the commitment of those who remain is also falling among our young and early middle-aged adults. The future of American Protestantism is in steep decline.
