The 20 best U.S. cities to trick-or-treat

eal-estate website Zillow ranked the 20 best U.S. cities to trick-or-treat in based on four equally-weighted variables: Zillow’s Home Price Index, population density, the site’s “Walk Score” (a measure of amenities within walking distance) and local crime data. According to Zillow, the list “represents cities that will provide the most candy, with the least walking and safety risks.”

San Francisco took the top spot, up from No. 2 last year, followed by Boston, Honolulu, Seattle and Chicago.
