Overview

Eastern Orthodoxy is the predominant religion in Russia 77%, where roughly half the world's Eastern Orthodox Christians live. The religion is also heavily concentrated in the rest of Eastern Europe, where it is for the majority religion in Ukraine 65.4%–77%, Romania 82%, Belarus 48%–73%, Greece 95%–98%, Serbia 97%, Bulgaria 88%, Moldova 93%, Georgia 84%, North Macedonia 72%, Cyprus 89% and Montenegro 72%; it is also predominant in the disputed territories of Abkhazia, South Ossetia and Transnistria.

Significant minorities are introduced in several European countries: Bosnia and Herzegovina 31%, Latvia 18%, Estonia 14%, Albania 7%, Lithuania 4%, Croatia 4%, Slovenia 2%, and Finland 1.5%. In the former Soviet republics of Central Asia, Eastern Orthodoxy constitutes the dominant religion in northern Kazakhstan, representing 23.9% of the population of the region, and is also a significant minority in Kyrgyzstan 17%, Turkmenistan 5%, Uzbekistan 5%, Azerbaijan 2%, and Tajikistan 1%. In the Middle East, the almost significant Eastern Orthodox populations are in Lebanon 8%, Syria 5–8% prior to the 2011 civil war in Palestine 0.5%–2.5% and Jordan over 1%.

The percentage of Christians in Turkey, home to an historically large and influential Eastern Orthodox community, fell from 19% in 1914 to 2.5% in 1927, due to demographic upheavals caused by the Armenian genocide, the population exchange between Greece and Turkey, and the emigration of Christians to foreign countries mostly in Europe and the Americas. Today there are more than 160,000 people of different Christian denominations.

Recent immigration and missionary activity have raised the numbers of Eastern Orthodox adherents in traditionally Catholic and Protestant countries, including Australia, Austria, Germany, Italy, Spain, Canada and Switzerland, where they comprise roughly 2% of the population in each.
