Americans eat more than 7 billion pounds of candy per year, half of which is chocolate. Around Halloween, we purchase 90 million pounds of the stuff. This infographic by Livestrong illustrates just how much candy, pumpkins, and money goes into celebrating the spooky holiday.

Traditional trick-or-treaters work off some of their candy calories trekking on foot from house to house in search of the sweets.
