Since the 1970s, Halloween celebrations have become increasingly popular among adults. The Halloween parade in the Greenwich Village neighborhood of New York City features elaborate satirical costumes and drunken revelry and serves as a model for many other adult Halloween celebrations around the country. Similarly boisterous public Halloween festivities are celebrated in San Francisco, California; New Orleans, Louisiana; and Key West, Florida.

Anoka, Minnesota, USA, the self-proclaimed "Halloween Capital of the World," celebrates with a large civic parade. Salem, Massachusetts, also has laid claim to the title, though Salem has tried to separate itself from its history of prosecuting witchcraft. Despite that, the city does see a great deal of tourism surrounding the Salem witch trials, especially around Halloween. Nearby Keene, New Hampshire hosts a Jack-O-Lantern festival each October which curently has the record for most pumpkins carved in a single day.
