THE US WITCH POPULATION HAS SEEN AN ASTRONOMICAL RISE
The mainstreaming of mysticism makes sense when you consider how it overlaps with the interests of the millennial women. As Wicker noted, witchcraft is the perfect religion for liberal millennials who are already involved in yoga and meditation, mindfulness, and new-age spirituality. With that foundation, they might show up for pagan holidays or new moon gatherings, or begin to explore the more serious spiritual concepts at the root of these practices.
This is all aided by the rise of witches on social media (just check out the extremely popular #witchesofinstagram hashtag on Instagram), and a certain kind of Instagrammable witchiness has been identified by market trend-spotters as "mysticore."
The Hoodwitch, for example, is a bona fide witch influencer, with 329K Instagram followers, who practices "everyday magic for the modern mystic," and appears at events like LA's BeautyCon to do tarot readings:
The numbers on Wicca and Paganism may well undercount the total number of witches. Indeed, as Necessary notes, some witches reject Wicca in its current form as "a new age less-than-perfect reinvention of witchcraft."
But whatever the exact number is, it's clear that witches are among usand the current trajectory suggests that their population will continue to grow.
