Willow Creek Association, out of 16,000-member mega church pioneer Willow Creek Community Church, now claims 4,000 members, 75% in the U.S. The most common definition of a mega church is one with regular attendance of 2,000 or more. Many of the Association’s members are smaller than this (average is 500), but want to learn successful growth techniques. The average American church has 92 people. (The GT 4/4/99)
