According to the International Herald Tribune, there are 2.35 million Muslims in the United States and on the whole, they’re pretty well-integrated:
As a whole, the poll found a largely content and hard-working U.S. Muslim population, and one that is fast assimilating.
Though 4 in 10 have arrived since 1990, a large proportion say their closest friends are non-Muslims. Their incomes are close to the national average. Even more than the general public, they say they believe that by working hard they can get ahead.
Eight in 10 said they were "very happy" or "pretty happy" with their lives. But young American Muslims – those under 30 – were more accepting of extremism. They were far more likely than their older counterparts to see themselves as Muslims first rather than as Americans first.
Black Americans who are Muslim converts, however, are more disaffected and more likely to endorse extremism than immigrant Muslims.
