The estimates made by muslim organizations is most accurate

As regarding your claims that the Islamic estimates are overblown: counting how many mosques are there in the United States, the mosque's capacity is previousely known. When the number of believers reaches the mosque capacity on Fridays (which happens in the vast majority of mosques in the US), thats a relatively accurate minimum number of muslims in that region (taking into account that not all muslims go to the mosque on Fridays). Then summing up with all the other mosques in the United States, gives the minimum total number of Islamic faith followers.

As you see it is easy and much more efficient than the surveys which are based on telephone calls.
Hoping that this clarifies the idea, I pray to Allah to guide you to the true path.
and may peace be upon the readers, regardless of their faith.
