This compares to the national average of 44 percent. Immigrant Muslims are well represented among higher-income earners, with 19 percent having annual household incomes of $100,000 or higher (compared to 16 percent for the Muslim population as a whole and 17 percent for the U.S. average). This is likely due to the strong concentration of Muslims in professional, managerial, and technical fields, especially in information technology, education, medicine, law, and the corporate world.[115]
