It is hard to put an exact number on Muslim Americans because the US Census does not note religion. However, the number of American Muslims is estimated to be between 2 and 7 million people. The Muslim population of the United States is only around 1% of the population.
Muslim Americans are primarily of Arab, South Asian, and African origin, but include a variety of other countries. The majority of Muslim Americans live in California, New York, Illinois, New Jersey, Indiana, Michigan, Virginia, Ohio, and Maryland.
