The census, by the Association of Statisticians of American Religious Bodies in Chicago, found that American Muslims almost doubled in the past decade.
It estimated that Muslims are now numbered at 2.6 million in 2010, from only one million in 2001.
Unofficial estimates put the number of Muslims in the US at between six to seven million...
The census also found that Muslims now outnumber Jews in much of the American Midwest and South.
The report attributes the sharp rise in the number of US Muslims to conversions and immigration.
The survey also estimates that there are more than 2,000 mosques across the United States, of which 166 are located in Texas.
An earlier Muslim study found that the number of mosques in the US jumped in the past decade to reach more than 2,000 mosques.
The study, released in February, also found that US Muslims are estimated at seven million.So which is it--2.6 or 7? And how is it possible for there to be two estimates that are so vastly different?
Update: Here's another (and altogether weirder) way to put it--counterintuitively, the number of Muslims in the U.S. has doubled since 9/11.
