So, did you hear that there are now more Wiccan believers in America than there are Presbyterians?

If you’ve been on social media lately, there is a good chance that you have heard this spin on some Wicca numbers from — Who else? — the Pew Research Center.

If you are looking for a blunt, crystalized statement of an alleged story in American culture, it never hurts to turn to The New York Post. Here is the top of a recent story that ran with this trendy headline: “Witch population doubles as millennials cast off Christianity.”

If you were interested in witchcraft in 1692, you probably would have been jailed or burned at the stake. If you’re interested in witchcraft in 2018, you are probably an Instagram influencer.

From crystal subscription boxes to astrologist-created lip balm, the metaphysical has gone mainstream. Millennials today know more about chakras than your kooky New Age aunt. That’s why it’s no surprise that the generation that is blamed for killing everything is actually bringing popularity to centuries-old practices.

According to the Pew Research Center (click here for .pdf), about 1.5 million Americans identify as Wiccan or pagan. A decade ago, that number was closer to 700,000. Presbyterians, by comparison, have about 1.4 million votaries.

It would be interesting to know how this story hatched at this time, seeing as how the Pew numbers — which are certainly interesting — are from 2014.

No doubt about it, this is a story. However, this specific twist on the numbers depends on definitions of two crucial terms — “Wiccans” and “Presbyterians.” It’s an interesting comment on the age in which we live that the first term is probably easier to define than the second.

So let’s think about that for a second, with the help of a GetReligion-esque piece by Mark Tooley, over at the Juicy Ecumenism blog. Yes, that site is operated by the conservative Institute on Religion & Democracy. However, I think this discussion — centering on the challenge of defining denominational terms — will be of interest to all journalists who are about accurate, when using statistics and basic religious terms. Here is a crucial statement early on:

… Faddish stories can sometimes be ginned up based on old numbers.
