Iraq Population 2015
Iraq, or the Republic of Iraq, lies in western Asia encircling the Mesopotamian plain, the northwestern part of the Zagros mountain range and the eastern branch of the Syrian desert. Syria lies on the northwest border of Iraq, Turkey is to the north, Iran is east, and Jordan is to the west. It has a narrow coastline of about 58km at the North Persian Gulf.
The Republic of Iraq has an area of 437,072 sq km and is mainly divided into 3 sections: a desert area in the west, a mountainous area in the north, and a large fertile plain in the middle of its southern area that is fed with water by the Euphrates and Tigris Rivers.
In 2015, Iraq has an estimated population of 36.3 million, which ranks 38th in the world. As a whole, Iraq has a population density of 83 people per square kilometer (184/square mile). The capital and largest city, Baghdad, has a population of 9 million. It's the Arab world's second-largest city after Cairo and the second-largest city in Western Asia behind Tehran. Other major cities include Basra (pop: 2.3 million), Arbil (2 million), Sulaymaniyah (1.6 million), Mosul (1 million), and Kirkuk (1 million).
Almost 75% of Iraq's population is made up of the dominant ethnic group -- the Iraqi or Mesopotamian Arabs. Other major ethnic groups include the Jurds (17%), Turkmen (3%), Assyrians (2%), and Persians (2%). There are about 20,000 Marsh Arabs in the southern part of the country and a population of 2,500 Chechens. Southern Iraq is also home to a community of Iraqis of African descent, who are descended from slaves prior to the Zanj Rebellion during the 9th century. Iraq was once home to a large Iraqi Jewish population of about 150,000 during the 1940s, although virtually all have left the country.
The official language in Iraq is Arabic, which is understood almost universally, although 10-15% of the population also speaks Kurdish. Islam is by far the most common religion at 95% of the population. Non-Muslims, mostly Assyrian Christians, make up 5% of the population. The Christian community in Iraq has existed for nearly 2,000 years and most are descended from the pre-Arab Mesopotamians-Assyrians. It's believed that 65% of Muslims are Shia while the remaining 35% are Sunni. Najaf and Karbala, Iraq are two of the holiest places for Shia Muslims.
Iraq has a large diaspora and nearly 2 million Iraqis have fled since the invasion in 2003, most going to Jordan and Syria. It's believed that there are almost 2 million people displaced within Iraq. The UN said in 2007 that almost half of Iraq's middle class population had fled persecution with no plans to return. Over half of Christians have fled the country since the U.S.-led invasion with almost 59,000 granted refugee-status citizenship in the United States. Meanwhile, there are about 160,000 Syrian refugees in Iraq who have fled the Syrian civil war.
