Religion in Iraq

Islam is the main Religion in Iraq and is followed by the majority of the population. According to the CIA World Factbook, approximately 95% to 98% of the people are Muslims.

Iran and Iraq are two of only a handful of countries with more Shias than Sunnis. While it is widely assumed that Iraq has a Shia majority, there is little reliable data on the exact Sunni-Shia breakdown of the population. As per estimates, it has a 50-55% Shia population and 40-42% Sunnis.

The remaining 5% follow Christianity, Yazidism, religious syncretism, Mandaeism, Shabakism, Yarsanism, and Zoroastrianism.
