Iraqis in Greece
The Iraqi Arabs who arrived in Greece are Muslims from the central and southern parts of Iraq, mostly Sunni with a tiny Shia minority. Sunni Arabs form 17 per cent of the total Iraqi population, which is almost an equal amount if not more than their Turkmen counterparts. Assyrians have a disproportionately large representation amongst Iraqis in Greece, this could be primarily because Greece has a Christian society, in which Iraqi Christians will find it easy to settle down in. Forming a quarter of the population in Greece, Iraqi Christians make up the majority of Christians from the Middle East, who arrived in Greece from the early 1990s.
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.
