The U.S. government estimates the population at 10.5 million (July 2018 estimate).  According to U.S. government estimates, Muslims, virtually all of whom are Sunni, make up 97.2 percent of the population and Christians 2.2 percent.  Groups constituting less than 1 percent of the population include Buddhists, Baha’is, Hindus, and Druze (who are considered Muslim by the government).  These estimates do not include migrant workers or refugees.  According to the Ministry of Labor (MOL), there are approximately 670,000 migrant workers in the country, mostly from Egypt, South and East Asia, and Africa.  Migrant workers from Africa and South and East Asia are often Hindu or Christian.  There are more than 757,000 refugees in the country registered with the UN High Commissioner for Refugees from 57 countries of origin, including approximately 670,000 Syrians and 67,000 Iraqis.  The Syrian and Iraqi refugee populations are mostly Sunni Muslim.  Shia Muslims and Christians account for less than one third of the Iraqi refugee population.
