Over the last decade, America’s 100 largest churches doubled in size :
In 2000, the 100 largest churches in the United States all had average weekly attendance of 4,000 people or more.In 2010, only churches with average weekly attendance of 8,000 or more made the 100 largest churches list, according to megachurch researcher John N. Vaughan.
About half the churches on the list (49 percent) are non-denominational.
Sixteen percent are in the Los Angeles area, while 7 percent are in Dallas and 7 percent are in Houston. (Atlanta finishes fourth with 6 percent of the megachurches.)
