Islam in the U.S. 2001

Fact Sheet: Islam in the United States

  • Islam is one of the fastest-growing religions in the U.S. By the year 2010, America's Muslim population is expected to surpass the Jewish population, making Islam the country's second-largest faith after Christianity.1

  • The American Muslim community is a mosaic of cultures, its members having come from all of the five major continents. In fact, a recent survey showed that most Muslims are immigrants -- 77.6% versus 22.4% U.S. born.2

  • This same survey indicated that the ethnic origins of the Muslim community are as follows:
    • 26.2%   Middle East (Arab)
    • 24.7%   South Asia
    • 23.8%   African American
    • 11.6%   Other
    • 10.3%   Middle East (Not Arab)
    •   6.4%   East Asia

  • While there are no official population figures for religious affiliation in the United States, experts estimate that there are approximately six million American Muslims. Other estimates range from four to eight million.3

  • The Britannica Book of the Year estimated that, in mid-2000, there were 4,175,000 Muslims in the United States, 1,650,000 of whom are African American in origin. An average of 17,500 African Americans converted to Islam each year between 1990 and 1995.4

  • The earliest group of Muslims to arrive in America in significant numbers came from West Africa from 1530 to 1851, because of the slave trade. They comprised an estimated 14% to 20% of the hundreds of thousands of West Africans forcibly removed from their homelands.5

  • The next sizable number of Muslims immigrated to the United States during the early 20th century. They came from Lebanon, Syria and other countries across the Ottoman Empire.6

  • The post-World War II era, during the 1960s and '70s, saw the third substantial wave of immigrants from all parts of the Islamic world. This wave included large numbers of Muslims who came to study at American universities.7

  • Approximately a third of American Muslims live on the East Coast (32.2%), 25.3% live in the South, 24.3% in the Central/Great Lakes Region, and 18.2% in the West. 8

  • There are nearly 2000 mosques nationwide as well as numerous Islamic day schools and Sunday and weekend schools.9
