Barna Research asked survey respondents about house churches by defining them as, “part of a group of believers that meets regularly in a home or place other than a church building. These groups are not part of a typical church; they meet independently, are self-governed and consider themselves to be a complete church on their own. Do you participate in such a group, sometimes known as a house church or simple church, that is not associated in any way with a local, congregational type of church?” The response to this inquiry consistently generates just 3% to 6% of all adults saying they have been involved in such an assembly during a typical month. Broader definitions of a house church generated “yes” answers from up to 33% of respondents. Barna Research reported in 2006 that 1 in 5 adults attend house churches. A follow-up study by Center for Missional Research commissioned a Zogby study that asked. “Do you meet weekly with a group of 20 people or less to pray and study Scriptures as your primary form of spiritual or religious gathering?” 26.3% of the 3,600 Americans polled answered “yes”.-Barna Update 31 Aug09
