Ratio of 'unchurched' up sharply since 1991: A Barna Group study
The portion of adults who generally do not attend church has risen sharply in the past 13 years, a Barna Group study shows. The percentage of Americans who are “unchurched” grew from 21 percent in 1991 to 34 percent in 2004. Researchers defined the unchurched as those who have not attended a church service in the past six months, other than on holidays such as Easter or Christmas, or events such as a funeral.
