Number of Goddess Worshipers

According to the web site, The Goddess Movement (http://www.paganlibrary.com/editorials/goddess_movement.php):

There are no estimates of the number of people worshipping this way, although journalist Margo Adler, in her book "Drawing Down the Moon," estimates there are 100,000 American pagans, people who call themselves witches, Druids or Goddess worshippers - people who "look to the old pre-Christian nature religions of Europe."
