document giving the results of the 1914 population
census. The total population (sum of all
millets) was 20,975,345, of which 1,792,206 were Greeks. The most common estimates for Ottoman Greeks killed from 1914 to 1923 range from 300,000 to 900,000. For the whole of the period between 1914 and 1922 and for the whole of Anatolia, there are academic estimates of death toll ranging from 289,000 to 750,000. The figure of 750,000 is suggested by political scientist
Adam Jones. Scholar
Rudolph Rummel compiled various figures from several studies to estimate lower and higher bounds for the death toll between 1914 and 1923. He estimates that 384,000 Greeks were exterminated from 1914 to 1918, and 264,000 from 1920 to 1922, with the total number reaching 648,000. Historian Constantine G. Hatzidimitriou writes that "loss of life among Anatolian Greeks during the WWI period and its aftermath was approximately 735,370". The pre-war Greek population may have been closer to 2.4 million. The number of Armenians killed varies from a low of 300,000 to 1.5 million. The estimate for Assyrians is 275–300,000. According to some calculations, during the autumn of 1922, around 900,000 Greeks arrived in Greece. According to
Fridtjof Nansen, before the final stage in 1922, of the 900,000
Greek refugees, a third were from
Eastern Thrace, with the other two thirds being from
Asia Minor. The estimate for the Greeks living within the present day borders of Turkey in 1914 could be as high as 2.130 million, a figure higher than the 1.8 million Greeks in the
Ottoman census of 1910 which included
Western Thrace,
Macedonia and
Epirus based on the number of Greeks who left for Greece just before World War I and the 1.3 million who arrived in the population exchanges of 1923, and the 300–900,000 estimated to have been massacred. A revised count suggests 620,000 in
Eastern Thrace including
Constantinople (260,000, 30% of the city's population at the time), 550,000
Pontic Greeks, 900,000 Anatolian Greeks and 60,000
Cappadocian Greeks. Arrivals in Greece from the exchange numbered 1,310,000 according to the map (in this article) with figures below: 260,000 from Eastern Thrace (100,000 had already left between 1912 and 1914 after the Balkan Wars), 20,000 from the southern shore of the
Sea of Marmara, 650,000 from Anatolia, 60,000 from
Cappadocia, 280,000 Pontic Greeks, 40,000 left Constantinople (the Greeks there were permitted to stay, but those who had fled during the war were not allowed to return). Additionally, 50,000 Greeks came from the
Caucasus, 50,000 from
Bulgaria and 12,000 from
Crimea, almost 1.42 million from all regions. About 340,000 Greeks remained in Turkey, 220,000 of them in
Istanbul in 1924. By 1924, the Christian population of Turkey proper had been reduced from 4.4 million in 1912 to 700,000 (50% of the pre-war Christians had been killed), 350,000 Armenians, 50,000 Assyrians and the rest Greeks, 70% in Constantinople; and by 1927 to 350,000, mostly in Istanbul. In modern times the percentage of Christians in Turkey has declined from 20 to 25 percent in 1914 to 3–5.5 percent in 1927, to 0.3–0.4% today roughly translating to 200,000–320,000 devotees. This was due to events that had a significant impact on the country's demographic structure, such as the
First World War, the genocide of Assyrians, Greeks, and Armenians, and the population exchange between Greece and Turkey in 1923. ==Historical background==
