U.S. megachurches more numerous, says Hartford Institute study
New research shows 50 percent more megachurches in the United States than previously thought.
Initial analysis of a cooperative project to survey all megachurches in the United States by Scott Thumma of Hartford (Conn.) Seminary's Hartford Institute for Religion Research, and Dave Travis and Warren Bird of Leadership Network, uncovered at least 1,200 Protestant churches that claim more than 2,000 weekly worship attendees.
