Membership Figures for the Orthodox Churches
It is difficult to obtain accurate statistics for numbers of Orthodox Christians worldwide. Below we provide estimates for the memberships of the different Local Orthodox Churches. It will be found that present membership comes to a rounded total for the whole Orthodox Church of nearly 217,000,000. Although this is far from the very high figures of 300,000,000 quoted by some and the very low figures of 100,000,000 quoted by others, we believe it to be fairly accurate. If any readers have access to more verifiable statistics, we would be pleased to adjust the figures below accordingly. The Local Orthodox Churches are listed in order of size.
1. The Russian Orthodox Church 164,001,000.
Also known as the Patriarchate of Moscow, this cares for Orthodox living in the canonical Russian Orthodox territories, which are spread over one sixth of the planet and are populated by over fifty nationalities. These multilingual territories include the Russian Federation, the Ukraine, Belarus, Moldova, Transcarpathia (the main part of Carpatho-Russia or Ruthenia), the Central Asian Republics and the Baltic Republics. The Russian Church also includes the multinational, self-governing Russian Orthodox Church Outside Russia (400,000 worldwide), the Autonomous Japanese Orthodox Church (25,000), the Autonomous Chinese Orthodox Church and some 200 other parishes and missions in the Orthodox ‘Diaspora’, that is, mainly in Western Europe, the Americas and Australia and also a mission in Thailand.
