Arabs are a minority of American Muslims and mostly Christian

Muslims are the most racially diverse faith community in the United States. Contrary to popular belief, Arabs make up a minority of Muslims, at only 30 percent, while 75 percent of Arabs in the United States are Christian. Approximately 30 percent of Muslims are African American, 30 percent are Middle Eastern and North African (classified as White in the US Census), 30 percent are South Asian, 5 percent are Latino, and 5 percent are multiracial. — Sahar F.
