On October 5, 2004 The New York Times reported, "facing increased discrimination after the Sept. 11 attacks, New York City's Muslims have identified more deeply with their religious roots, setting aside the sectarian and linguistic differences that have traditionally divided them, according to a six-year study released yesterday by Columbia University. The study, financed by the Ford Foundation, provides the most comprehensive look yet at the religious, social and political affiliations of New York City's estimated 600,000 Muslims both before and after Sept. 11, 2001, and involved work by more than a dozen academic researchers and professors."
