...a plurality of Muslim Americans--about one-third--are of South Asian descent; 26% are Arab and another 20% are American blacks. But until 2001 we had no idea how many Muslims lived in America, and even now the figure remains a matter of intense controversy. All major Muslim advocacy groups put the number at above six million...all independent surveys put the real figure at no more than three million, while the most credible study to date, by Tom Smith of the University of Chicago's National Opinion Research Center, estimates total Muslim population at 1,886,000. "[It] is hard to accept that Muslims are greater than one percent of the population," he writes.
Whatever the real figure, what's reasonably clear is that Muslim Americans, like Arab-Americans, have fared well in the U.S. The Zogby survey found that 59% of American Muslims have at least an undergraduate education, making them the most highly educated group in America. Muslim Americans are also the richest Muslim community in the world, with four in five earning more than $25,000 a year and one in three more than $75,000. They tend to be employed in professional fields, and most own stock, either personally or through 401(k) or pension plans. In terms of civic participation, 82% are registered to vote, half of them as Democrats.
...21% of Muslim Americans intermarry, according to the 2001 Religious Identification Survey of the City University of New York--close to the national rate of 22% of Americans who marry outside their religion...[A]ccording to Ishan Bagby, a professor at the University of Kentucky who recently made a study of mosque attendance in Detroit, the average mosque-goer is 34 years old, married with children, has at least a bachelor's degree, and earns about $74,000 a year.
