An estimated 1 to 1.5 million people say they practice Wicca or paganism, a rise from an estimated 8,000 Wiccans in 1990, and 340,000 in 2008.
In 2014, a Pew Research Center survey found about 0.4 percent of Americans identify themselves Pagan or Wiccan, a significant increase over prior years.
If accurate, the Pew data would suggest that there are more self-identified "witches" in the United States than members of some mainline Protestant denominations. For example, according to 2017 figures, there are 1.4 million practicing Presbyterians in the United States.
Wicca is a form of modern pagan witchcraft begun in the 1940s and 1950s in the United Kingdom. Those who practice Wicca often refer to themselves as “witches.” People who practice other forms of witchcraft may not identify with the "Wiccan" or "pagan" label, meaning that the number of self-identified witches in the United States might actually be higher than reported.
