Nobody knows how many Wiccans that there are. We have a hunch that few personal estimates are accurate within 50%.
When we started to research this question, we assumed that we could find a few
reasonably accurate estimates, compute their average, and present the result as a
ballpark number of the number of Wiccans in the U.S. But it was not to be. We found estimates by individuals as low as
2,000 Wiccans in 1982 and 3,600 in 1996.
At the other extreme, Phyllis Curott, author of Book of Shadows, estimated 5 to 10 million in 1999. 1 There have been a few surveys conducted by polling companies which numbers based on hard evidence. But these polls have problems that we feel significantly underestimate the number of Wiccans in the U.S.
