According to online real estate data provider, Zillow. Their methodology?
"We theorized that homes in more expensive neighborhoods would give out bigger, better candy. However, wealthy neighborhoods are not always the best for harvesting the most Halloween candy. For parents and kids alike, the walkability and density of a neighborhood is key to covering the most ground, in the fastest time, to collect the most candy. Safety, of course, is also a primary concern for parents on Halloween, thus adding crime data to the Index was a no-brainer."
Doesn't hurt that the Pacific NW (we include San Fran when it's convenient...) has a very high Happy Heathen index (i.e. lowest "religious" population in the country). We do like our Pagan holidays.
Over the next two weeks the folks at Zillow will be rolling out neighborhood-specific stats within those top 20 ghoul-friendly communities.
