Assyrian populations are distributed between the Assyrian homeland and the Assyrian diaspora. There are no official statistics, and estimates vary greatly, between less than one million in the Assyrian homeland,[1] and 3.3 million with the diaspora included,[62] mostly due to the uncertainty of the number of Assyrians in Iraq and Syria. Since the 2003 Iraq War, Iraqi Assyrians have been displaced into Syria in significant but unknown numbers.
