An unprecedented amount of public attention focused on Muslim Americans in the wake of the terrorist attacks of Sept. 11, 2001. The U.S. Muslim population has grown in the two decades since, but it is still the case that many Americans know little about Islam or Muslims, and views toward Muslims have become increasingly polarized along political lines.
As their numbers have increased, Muslims have also reported encountering more discrimination. In 2017, during the first few months of the Trump administration, about half of Muslim American adults (48%) said they had personally experienced some form of discrimination because of their religion in the previous year.
In a March 2021 survey, U.S. adults were asked how much discrimination they think a number of religious groups face in society. Americans were more likely to say they believe Muslims face “a lot” of discrimination than to say the same about the other religious groups included in the survey, including Jews and evangelical Christians.
Though many Americans have negative views toward Muslims and Islam, 53% say they don’t personally know anyone who is Muslim, and a similar share (52%) say they know “not much” or “nothing at all” about Islam.
