Answer:
There are several approaches to quantify American belief in so-called paranormal events. One method is to question a representative sample of the population whether they believe in ghosts. In a 2019 IPSOS poll, 46 percent of respondents claimed they did.
Another is to inquire as to what they are afraid about. According to the Chapman University Survey of American Fears this year, approximately 9% of 1,035 adults polled were terrified of ghosts, and the same percentage were afraid of zombies; many more were afraid of government corruption, the coronavirus, or significant civil disturbance.
The last time Gallup surveyed people about ghosts, in 2005, 32 percent of respondents said they believed in “ghosts or that spirits of dead people can come back in certain places and situations.” When Gallup asked the same question in 1990, the result was 25 percent.
I personally do not believe in ghosts, however I did when I was a toddler.
