What is an Evangelical?

When measuring the social, political, religious and behavioral characteristics of evangelicals, the Barna Group found major differences between self-described evangelicals and Americans who are “evangelical” according to a nine point criteria of theological belief. Almost 40% percent of Americans are self-described “evangelicals.” But when nine basic theological beliefs are used as the criteria for who is evangelical, that number drops to a mere 8% of Americans; approximately 18 million adult Americans.
