That’s a LOT of witches! I’ve encountered a few different articles on this lately, and from my own research, it seems to be true. From an article in Quartz by Sangeeta Singh-Kurtz & Dan Kopf in October this year, “Although Trinity College hasn’t run a survey since 2008, the Pew Research Center picked up the baton in 2014. It found that 0.4% of Americans, or around 1 to 1.5 million people, identify as Wicca or Pagan—which suggests continued robust growth for the communities.”
I often hear, “are there enough healers, witches, magicians and artists on the planet to heal our society? Well it appears the numbers are climbing, and hopefully healing will spread along with it. 🙂
Source: The US witch population has seen an astronomical rise
“Though the data is sparse, what we do know is that the practice of witchcraft has seen major growth in recent decades. As the witch aesthetic has risen, so has the number of people who identify as witches.
The best source of data on the number of witches in the US comes from assessments of the Wicca population. Not all people who practice witchcraft consider themselves Wicca, but the religion makes up a significant subset, as Alden Wicker noted for Quartz in 2016.
Wicca is a largely Western religious movement that dates back to the mid-20th century in the US and UK. According to the site wicca.com, it’s a belief system informed by “pre-Christian traditions originating in Ireland, Scotland, and Wales,” that promotes “free thought and will of the individual, and encourages learning and an understanding of the earth and nature.
From 1990 to 2008, Trinity College in Connecticut ran three large, detailed religion surveys. Those have shown that Wicca grew tremendously over this period. From an estimated 8,000 Wiccans in 1990, they found there were about 340,000 practitioners in 2008. They also estimated there were around 340,000 Pagans in 2008.
Here’s another article I found with good information.
