The Assyrian community in Iran numbered approximately 200,000 prior to the Islamic Revolution of 1979. In 1987, there were an estimated 50,000 Assyrians living in Tehran. However, after the revolution many Assyrians left the country, primarily for the United States; the 1996 Iranian census counted only 32,000 Assyrians. Current estimates of the Assyrian population in Iran consist of 7,000 combined members of the Assyrian Church of the East and Chaldean Catholic Church in addition to less than 10,000 members of the Assyrian Evangelical Church.
