The Muslim population in the United States is somewhere between 2.6 million and 7 million people as of 2012. Although Muslims make up less than 1 percent of the population, Islam is the third largest religion in the United States after Christianity and Judaism.
According to the 2010 U.S. Religion Census, 2.6 million Muslims live in the United States. This number represents an increase of around 160 percent in the Muslim population since the previous survey came out in 2000. A Pew Research survey concluded in 2011 places the number of Muslims in the United States at 2.75 million. The Council on American-Islamic Relations, a Muslim civil-liberties advocacy group, estimates that between 6 and 7 million Muslims live in the United States.
