Demographics of Iraq
97% of Iraqis follow Islam: 61% Shia and 34% Sunni. 1% of these describe themselves as "Just a Muslim". According to the CIA Factbook, Shias make up 60% of population, while Sunnis 35%. Christianity accounts for 5%, and the rest practice Mandaeism, Yazidism and other religions.
Shia Muslims in the Arab world
Unlike other sects of Islam, the Shias of Iraq have been treated horrifically under the regime of Saddam Hussein, when many Iraqi Shī‘as of Persian descent were expelled from the country in the 1980s, despite being the majority of the country at 83%. Reports indicated that no neighborhood was left intact after the 1991 uprising in Karbala. In the vicinity of the shrines of Husayn ibn Ali and Abbas ibn Ali, most of the buildings surrounding the shrines were completely reduced to rubble. The shrines themselves were scarred from bullet marks and tank fire. They were, however, quickly restored by Shiite Donations.
