According to a 2007 Pew Research survey, two-thirds of Americans (68%) completely or mostly agree that angels and demons are active in the world (and not just on Halloween). Just 14% completely disagree with this idea. Among religious groups, Mormons (88%), evangelical Christian (87%) and members of historically black churches (87%) are the most likely to agree that angels and demons are active in the world. Jewish Americans are by far the most likely to disagree that these spirits stalk the planet (73% disagree with 52% completely disagreeing). Buddhists (56% disagree), Hindus (55%) and the religiously unaffiliated (54%) are other faith groups disagreeing that angels and demons exist in our world. Happy Halloween!
