Shia–Sunni relations
Shia–Sunni discord in Iraq starts with disagreement over the relative population of the two groups. According to most sources, including the CIA's "World Factbook", the majority of Iraqis are Shia Arab Muslims (60%-70%), and Sunni Arab Muslims represent between 32% and 37% of the population. However, Sunni are split ethnically among Arabs, Kurds and Turkmen. Many Sunnis hotly dispute their minority status, including ex-Iraqi Ambassador Faruq Ziada, and many believe Shia majority is "a myth spread by America". One Sunni belief shared by Jordan's King Abdullah as well as his then Defense Minister Shaalan is that Shia numbers in Iraq were inflated by Iranian Shias crossing the border. Shia scholar Vali Nasr believes the election turnout in summer and December 2005 confirmed a strong Shia majority in Iraq.
Baghdad
Baghdad's population was estimated at 7.22 million in 2015. The city historically had a predominantly Sunni population, but by the early 21st century around 82% of the city's population were Iraqi Shia. At the beginning of the 21st century, some 1.5 million people migrated to Baghdad, most of them Shiites and a few Sunnis.Sunni muslims make up 30-35% of Iraq's population and they still majority in west and north Iraq.
