Exact definitions of "congregations" and "adherents" vary by religious body. Congregations may be parishes, churches, synagogues, mosques, temples, or another site where a religious body has regularly scheduled worship services. Adherents generally are members, children who are not members, and others who are not members but are considered participants in the congregation.
