A little tired of the crowing from the Muslim advocacy organizations about how there are six-to-twelve million Muslims in the US? That they're the fastest growing American religion? That they're the second largest religion in the U.S.?

Well, don't believe it. These beliefs are undocumented by evidence.

The best study in the US on this topic is done every 10 years by CCNY, in what is known as the ARIS Study, or American Religious Identification Study.

The first problem one deals with in religious demographics is to determine what information really matters. What religion a person is born with? Or,  what they consider themselves? ARIS, quite logically, focuses on the latter, since the former does not take into account conversion from one religion to another, nor does it take into account the fact that people do immigrate in, and emigrate out. . (Obviously, pro-Islamic groups want to use birth religion as the ultimate determinator. It pumps up their numbers.)

ARIS 2001 managed to identify no more than 1.4 million Muslims in the US, a far cry from the six to twelve million the Muslims themselves claim. The fastest growing religion in the US is not Muslim but Wicca, but even among the religions who have "critical mass" statistically, Islam was fourth-largest (behind Christianity, Judaism, and "No Religious Affiliation") and was growing at a rate that by today (2007) would put it BEHIND Hinduism and Buddhism, both of which have FAR more robust growth rates.  (To be fair to the Muslims, they are correct that their growth rate, and the shrinkage rate of Judaism, ought to have put them ahead of Judaism by now. So, that puts Islam in the number 5 slot, behind Christianity, NRA, Hinduism, and Buddhism.)

Also, the survey was taken PRIOR to 9/11, which accelerated the emigration of Muslims from the US (both voluntarily and involuntarily) and erected barriers to their future immigration.

But, what's truth when you're politicing?
