Halloween, which first became popular in the US during the 1800s, has become a multi-billion-dollar industry, including candy, movies, haunted experiences, and creepy costumes.

WalletHub shared a study with Insider in 2022 that breaks down Halloween by the numbers, such as how much money people spend on the holiday, how many kids are expected to dress as princesses, and the most popular Halloween costume for your pets.

The first citywide Halloween celebration took place in Anoka, Minnesota, in 1921.

According to WalletHub, the best place to celebrate is usually New York City, based on the fun activities on offer, the weather, and "trick-or-treater friendliness."

Around 69% of Americans celebrate Halloween, according to WalletHub.

But only 67% of Americans plan on giving out candy to trick-or-treaters.

And while it's a huge industry, with a projected $10.6 billion spent this year, not everyone spends mega bucks.

But, like everything else, inflation has affected Halloween. The average price of a pumpkin is $5.82, up 13% from last year.

But the average person will spend around $100 this year on Halloween.

But the 28% of people who are throwing a Halloween party will probably end up spending a bit more.

Of that $10.6 billion, $3.1 billion will be spent on candy for the estimated 41.7 million trick-or-treaters this year.

The first documented use of "trick or treat" was in 1917.

But not all that candy goes to the kids — 86% of parents have admitted to stealing their children's candy.

The most popular candies in the US are:

1. Reese's Cups
2. Skittles
3. M&M's
4. Starburst
5. Hot Tamales

At least $3.6 billion will be spent on costumes this year.

Costumes have definitely become more elaborate over the years.

This year, 1.6 million children are expected to dress as witches, 4.6 million as superheroes, and 1.9 million as princesses.

If you want to help your child be a little more creative, here are some ideas.

Meanwhile, among adults, there will be 1.7 million vampires and 5.3 million witches stalking the streets this year.

Animals won't miss out on the fun — 20% of Americans dress their pets in costumes.

The most popular costumes this year for pets are pumpkins, hot dogs, bats, bumblebees, and witches, according to WalletHub.

The record for the longest walk-through haunted house is 7,183 feet, nearly a mile and a half.

It's held by Dragon's House of Horror in Albuquerque, New Mexico.

But if haunted houses aren't your speed, you could always check out a scary movie. In 2022 (so far), horror movies made $412 million at the US box office.
