ELMWOOD — The Trick-or-Treat Route Optimization Board has published its annual 58-page guide to maximizing “candy ROI” — return on investment, measured in candy-per-minute — calling this year’s edition “our most data-driven Halloween yet.”
The guide — titled “Sweet Streets 2026: A Trick-or-Treater’s Almanac” — includes heat maps of high-yield neighborhoods, a ranked list of the county’s 200 most generous houses (“the full-size corridor,” pages 12-19), and a formula for calculating optimal route efficiency: candy value divided by walking time, adjusted for “porch-light reliability” and “the raisin factor.”
“The raisin factor is critical,” said board chairwoman Dr. Emily Hart, a former logistics consultant who, per her bio, “once optimized a warehouse and now optimizes Halloween.” “A house that gives raisins has a negative ROI. Not zero — negative. You walked there. You said ‘trick or treat.’ You got a raisin. That’s a loss.”
The guide’s key findings: the optimal trick-or-treat window is 6:12 p.m. to 8:47 p.m. (“the golden 155 minutes”), cul-de-sacs outperform through-streets by 23%, and houses with inflatable decorations give 31% more candy — “the inflatable-to-generosity correlation is the strongest in our dataset,” Hart said.
New this year: the “Candy Portfolio Diversification” chapter, advising trick-or-treaters to balance chocolate (growth), gummies (stable), and “speculative assets” like full-size bars (“rare, volatile, life-changing”).
“We’re not telling kids to skip houses,” Hart said. “We’re telling them to skip houses strategically. There’s a difference. One is rude. The other is analytics.”
Parents have embraced the guide. “We planned our route in August,” said father of three Greg Tillman, holding a laminated map with color-coded zones. “The kids think it’s a treasure map. It is a treasure map. The treasure is candy. The map is science.”
The board will publish a post-season report November 3, including “actual vs. projected yields” and “the year’s biggest candy upset” — last year’s winner: “a dentist’s house that gave out full-size bars, which nobody predicted, least of all the board.”
