Real American Church Attendance?

By D. Michael Lindsay

Pinpointing the number of Americans in weekly worship has vexed sociologists and pollsters for quite some time.  In 1993, an article by three prominent scholars appeared in the flagship sociology journal which suggested an argument similar to that of David Olson and Bob Smietana.  Using actual headcounts in worship instead of nationally-representative polls where people report how often they attend church, they suggested weekly worship attendance is closer to 20 percent of the adult population than the widely-reported 40 percent.

Since then, a number of experts have responded.  The debates have been intense, but in recent years, the following consensus has emerged:

Counting heads to estimate weekly worship service attendance is far less reliable than estimates based on survey responses.  Headcounts are more error-prone because there is more room for biases—from who does the counting, from when the headcounts are conducted, from who reports the headcounts, and from how exhaustive the headcounts are (such as whether midweek services are included).

In order for researchers to generalize headcounts to the entire adult population, they must be conducted as an exhaustive census or a representative sample.  Typically, headcounts are not statistically representative in terms of denomination, region of the country, or time of year.  Even weather patterns have to be included in the mix, which means headcounters have to devote incredible resources in order for their estimates to be accurate.  Most of the time, that does not happen.

The gold standard to assess whether survey estimates about church attendance are accurate is to see how well they predict the outcome of U.S. presidential elections, where we eventually learn the actual outcome.  Gallup and other survey firms use the same methods to predict presidential races as they use to estimate worship attendance.  And we know that people over-report voting as much as they over-report church attendance.  Hence, if Gallup estimates can successfully overcome that bias in predicting who will win the White House, we can be reasonably confident in their estimates about church attendance.  Gallup hasn’t missed a presidential race in sixty years, which is an impressive track record.

And yet, we know over-reported behavior is a problem.  Men over-report sexual adventures, and citizens claim to vote when they never actually show up on Election Day.  So also do Americans exaggerate church attendance.  Using a variety of cross-checks on reported behaviors, social scientists have concluded that Americans do over-report church attendance but not by much.  Instead of an over-reporting factor of 2 to 1 (which would make weekly church attendance around 20 percent), it is probably a margin of 1.3 to 1.  This makes weekly attendance figures somewhere between 30 and 35 percent of the U.S. adult population.

With these caveats in mind, social scientists continue to trust survey estimates of church attendance.  Pastors and church leaders should do the same.
