Ethnic Origins of American Muslims

Here's another surprise. According to the U.S. State Department, only 25% of American Muslims are Arab. Here's the complete breakdown:

South Asian (Pakistani, Indian, Bangladeshi, Afghani) = 33 percent
African-America = 30 percent
Arab = 25 percent
Sub-Saharan African = 3.4 percent
European (Bosnian, Tartar, Kosovar, etc.) = 2.1 percent
White American = 1.6 percent
Southeast Asian ( Malaysian, Indonesian, Filipino) = 1.3 percent
Caribbean = 1.2 percent
Turkish = 1.1 percent
Iranian = 0.7 percent
Hispanic/Latino = 0.6 percent

Total population numbers are disputed by some. The same government page lists the number of American Muslims "associated with a mosque" at 2 million, though other groups say the number is much higher. Here's a range of articles:
