The percentage of Christians in Turkey fell from 19 percent in 1914 to 2.5 percent in 1927,[18] due to events which had a significant impact on the country's demographic structure, such as the Armenian Genocide, the population exchange between Greece and Turkey,[19] and the emigration of Christians to foreign countries (mostly in Europe and the Americas).[20] Today there are more than 160,000 people of different Christian denominations.[21]
