20 Interesting Halloween Facts

1. Halloween is roughly 2,000 years old. Its roots are in the ancient Celtic festival of Samhain, celebrated across Ireland, Scotland, and the Isle of Man around October 31. The Celts believed this date marked a thin spot between the living world and the spirit world, when ghosts of the dead returned to earth. Costumes, bonfires, and food offerings were used to ward them off.
2. The first jack-o'-lanterns were carved from turnips. In Ireland and Scotland, people hollowed out turnips, potatoes, and beets, placed embers inside, and set them in windows to scare away wandering spirits. When Irish immigrants arrived in North America in the 1800s, they discovered pumpkins were native, larger, and dramatically easier to carve - and the modern jack-o'-lantern was born.
3. The name "jack-o'-lantern" comes from an Irish folktale. Stingy Jack was said to have tricked the Devil twice and was barred from both Heaven and Hell. He was forced to wander earth forever with only a burning coal inside a hollowed turnip. The Irish called the figure "Jack of the Lantern," eventually shortened to jack-o'-lantern.
4. Halloween is the second-largest commercial holiday in America. Only Christmas generates more retail spending. According to the National Retail Federation, total U.S. Halloween spending exceeded $12.2 billion in 2023, covering costumes, candy, decorations, and parties. Roughly 73% of Americans participate in Halloween in some form, making it one of the most-celebrated non-religious holidays in the country.
5. Americans spend $3.6 billion on Halloween candy alone. Reese's Peanut Butter Cups consistently top the list of America's favorite Halloween candy, followed by Skittles, M&M's, Snickers, and Hershey's. Candy corn, invented in the 1880s by the Wunderle Candy Company, was originally marketed as "Chicken Feed" because corn was used as livestock feed at the time.
6. Black cats were believed to be witches' familiars. In medieval Europe, black cats were thought to be witches in disguise or supernatural companions that helped cast spells. The superstition led to mass killings of black cats, which some historians link to the spread of the Black Death since fewer cats meant more rats. Many U.S. shelters still pause black cat adoptions in October.
7. The world's largest pumpkin weighed 2,749 pounds. Grown by Travis Gienger in Anoka, Minnesota and weighed at the 2023 Safeway World Championship Pumpkin Weigh-Off in Half Moon Bay, California, this giant set the all-time world record. Competitive pumpkin growers feed their entries custom diets and shelter them with shade tents and misters during peak summer growing months.
8. Trick-or-treating evolved from medieval "souling." In the Middle Ages, poor people - especially children - would go door-to-door on All Hallows' Eve offering prayers for the dead in exchange for small "soul cakes." In Scotland and Ireland, this evolved into "guising," where children performed a song, joke, or trick before receiving a treat. American immigrants brought the custom in the 1800s.
9. The phrase "trick or treat" first appeared in 1927. The earliest known printed use was in a Canadian newspaper from Blackie, Alberta, describing children demanding treats with the threat of pranks. The phrase didn't catch on widely in the United States until the late 1930s and was nearly extinguished by World War II sugar rationing before roaring back in the 1950s.
10. Samhainophobia is the fear of Halloween. The clinical phobia is named after the Celtic festival Samhain. Sufferers report panic responses to costumes, decorations, jack-o'-lanterns, and even Halloween imagery in stores. Related phobias include phasmophobia (fear of ghosts), wiccaphobia (fear of witches), and coulrophobia (fear of clowns) - all of which spike around late October.
11. Michael Myers' mask is a painted Captain Kirk. The 1978 film Halloween had a $300,000 budget and no money for a custom mask. The prop department bought a $1.98 William Shatner Star Trek mask, painted it white, teased the hair, and reshaped the eye holes. The film grossed over $70 million and spawned one of horror's most recognizable franchises.
12. The Stanley Hotel inspired Stephen King's The Shining. In 1974, Stephen and Tabitha King were the only guests at the Stanley Hotel in Estes Park, Colorado, on its closing night for the season. King stayed in Room 217, dreamed of his son being chased through the hallways by a fire hose, and woke up with most of The Shining outlined in his head. The hotel still books Room 217 today.
13. Halloween costumes for pets generate $700 million annually. The National Retail Federation tracks pet costume spending separately because it has grown so dramatically. Pumpkin is consistently the most popular pet costume, followed by hot dog, bumblebee, devil, and ghost. Roughly 1 in 5 Americans now dresses up at least one pet for Halloween, with dogs leading cats by a wide margin.
14. Illinois grows more pumpkins than any other state. Roughly 80% of all U.S. pumpkins for canning come from a 90-mile radius around Morton, Illinois - home to the Libby's pumpkin processing plant. Illinois produces over 500 million pounds of pumpkins each year, more than the next four states combined. Most are processed pumpkins; carving pumpkins are a separate market.
15. The most expensive pumpkin pie cost $42,000. Created for a Washington, D.C. charity auction by chef Jeffrey Buben, the record-setting pie featured rare ingredients, edible gold leaf, and was served in a hand-decorated heirloom pan. Standard supermarket pumpkin pies, by contrast, average about $5 - making this single pie roughly 8,400 times more expensive than the typical Thanksgiving dessert.
16. Black and orange are Halloween's official colors for symbolic reasons. Black represents death, darkness, and the long winter ahead - the very themes Samhain marked. Orange symbolizes the autumn harvest, fire, and the changing leaves. The pairing dates back to ancient Celtic seasonal symbolism and was cemented by mass-produced Halloween cards and decorations in the early 1900s.
17. The Catacombs of Paris hold over 6 million bodies. Beneath the streets of Paris, 200 miles of tunnels store the carefully arranged bones of millions of former residents, transferred from overflowing cemeteries between 1786 and 1860. Only about a mile of the catacombs is open to tourists, but the site has become one of the most visited Halloween-season attractions in Europe.
18. Bobbing for apples comes from a Roman festival. When Romans conquered Celtic territories, they merged Samhain with their own festival of Pomona, goddess of fruit and orchards. Pomona's symbol was the apple. The bobbing tradition was originally a Roman courtship ritual - the first young person to bite an apple was said to be the next to marry.
19. Halloween was nearly canceled by the candy industry. In the 1970s, urban legends about poisoned candy and razor blades in apples caused a national panic. Hospitals offered to X-ray candy, and many parents banned trick-or-treating outright. Subsequent FBI and academic studies found that nearly every reported case was either a hoax or a family-related incident, not random tampering.
20. The largest Halloween parade is in New York City. The Village Halloween Parade in Greenwich Village, founded in 1973 by puppeteer Ralph Lee, now draws roughly 60,000 costumed marchers and 2 million spectators each year. It is the only major nighttime parade in America, runs for over a mile up Sixth Avenue, and is broadcast live on NY1 every October 31.
