“A new report from The Barna Group, based on interviews with more than 3,000 adults, shows that congregational size is related to the nature of a congregation’s religious beliefs, religious behavior and demographic profile. There are clearly significant differences between the smallest and largest of Protestant churches in terms of the theological beliefs of adherents.”
 

One of the survey results discovered was that most people in the USA attended smaller churches:

“Despite the substantial attention focused on Protestant mega-churches, such congregations draw about 9% of adults who frequent a Protestant church. In contrast, 41% of adults attending a Protestant church associate with a congregation of 100 or fewer adults. An additional 23% can be found at churches of 101 to 200 adults, 18% associate with bodies of 201 to 499 adults, and 9% can be found in churches of 500 to 999 adults.” © The Barna Group, Ltd, 2009
