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.
Islam in Turkey
According to religiosity polls, 97.8% of the population identifies as Muslim, and only 2% is non-religious. Most Muslims in Turkey are Sunnis, forming about 78% of the overall Muslim denominations. The remaining Muslim sects forming about 20% of the overall Muslim population consist of Alevis, Ja'faris (representing 4%) and Alawites (with an estimated population of around 1 million) which is about 1% of the overall Muslim population in Turkey. 
Figures on NDM's or Non-denominational Muslims vary with estimates ranging from 2 percent of the population to 14 percent of the population.
