The most popular treat for Halloween trick-or-treaters are candy bars with Snickers being the most popular

Although some popular histories of Halloween have characterized trick-or-treating as an adult invention to rechannel Halloween activities away from vandalism, there are very few records supporting it. Des Moines, Iowais the only area known to have a record of trick-or-treating being used to deter crime. Elsewhere, adults, as reported in newspapers from the mid-1930s to the mid-1950s, typically saw it as a form of extortion, with reactions ranging from bemused indulgence to anger. Likewise, as portrayed on radio shows, children would have to explain what trick-or-treating was to puzzled adults, and not the other way around. Sometimes even the children protested: for Halloween 1948, members of the Madison Square Boys Club in New York City carried a parade banner that read “American Boys Don’t Beg.” The National Confectioners Association reported in 2005 that 80 percent of adults in the United States planned to give out confectionery to trick-or-treaters, and that 93 percent of children, teenagers, and young adults planned to go trick-or-treating or participating in other Halloween activities. In 2008, Halloween candy, costumes and other related products accounted for $5.77 billion in revenue.
