Eastern Liturgical (Orthodox) Family

The Eastern Liturgical (Orthodox) family represents one of the three great divisions of Christianity; the others are the Protestant churches and the Roman Catholic Church. The Catholic and Orthodox churches were originally united, but they parted in the 11th century, when they differed over several points of doctrine, including the supreme authority of the pope, which Orthodox Christians reject. Since the 20th century, the Catholic and Orthodox churches have made greater efforts toward reconciliation. Churches in the Eastern Liturgical family include the Greek Orthodox Archdiocese of America and the Orthodox Church in America.

1 Congregational adherents include all full members, their children, and others who regularly attend services. The adherence rate is the number of people per 1,000 who are an adherent of the group. For example an adherence rate of 600 means that 600 out of every 1,000 people in this area are adherents of the Southern Baptist Convention.

These data were collected by the Association of Statisticians of American Religious Bodies (ASARB) and include statistics for 236 religious groups, providing information on the number of their congregations and adherents within each state and county in the United States. Clifford Grammich, Kirk Hadaway, Richard Houseal, Dale E. Jones, Alexei Krindatch, Richie Stanley and Richard H. Taylor supervised the collection. These data originally appeared in 2010 U.S. Religion Census: Religious Congregations & Membership Study, published by the Association of Statisticians of American Religious Bodies (ASARB).
