More than two-thirds of Americans plan on celebrating Halloween.
The first citywide Halloween celebration took place in Anoka, Minnesota, in 1921.
And while it's a huge industry, with a projected $8.8 billion being spent, not everyone will spend mega bucks.
In fact, 76% of Americans will spend $50 or less to celebrate the spookiest day of the year.
But of that $8.8 billion, at least $3.2 billion will be spent on costumes.
This year, 1.3 million children are expected to dress as witches, 2.4 million as superheroes, and 3.1 million as princesses.
Meanwhile, among adults, there will be 2 million vampires and 5 million witches stalking the streets.
Animals won't miss out on the fun as 17% of Americans dress their pets in costumes.
$2.6 billion will be spent on candy for when the estimated 41 million trick-or-treaters hit the streets.
But not all that candy goes to the kids — 72% of parents have admitted to stealing their children's candy.
But there are other things to do besides trick or treat. Over $300 million is made annually from ticket sales for haunted attractions.
A large haunted house can make as much as $2 million during the Halloween season.
Speaking of large haunted houses, the record for the longest walk-through haunted house is 7,183 feet, 8.4 inches — nearly a mile and a half.
But if haunted houses aren't your speed, you could always check out a scary movie. In 2018, horror movies made $902 million at the US box office.
Or you could try out a parade. In New York City, 2 million spectators will watch 60,000 participants march in the Halloween Parade.
