How Many Muslims and Arab Americans Live in the U.S.? Latest Verified Figures
A detailed look at the current population estimates for Muslim and Arab communities in America based on the latest 2020 data.
According to the most recent estimates from the 2020 U.S. Religion Census, there are approximately 4.45 million Muslims living in the United States, making Islam the third-largest religion in the country at 1.34% of the total population.
Arab Americans
Accurate counting has historically been challenging. The 2020 U.S. census, for the first time, invited write-in responses for the Middle Eastern and North African (MENA) category. The data revealed around 3.5 million Americans of MENA descent, which includes Arab Americans.
Meanwhile, the Arab American Institute (AAI)—using broader demographic models and accounting for undercounting—estimates the Arab American population at approximately 3.7 million.
