Halloween map tracks trick-or-treat hotspots in Toronto

A pair of stat nerds have used census data to map trick-or-treat hotspots in Toronto and across the country.

Trying to figure out just how much candy you should stock up on for Halloween? If you're always trying to guess how many trick-or-treaters to expect at your door, this year you're in luck.

A new Canada-wide map created by Vancouver software developer Jens von Bergmann and colleague Alejandro Cervantes uses census data to let you determine if your neighbourhood is a Halloween hotspot. 

Von Bergmann used what Statistics Canada calls "prime trick-or-treating age," which is defined as between five and 14 years old.

Von Bergmann has divided the number of children in that age group by the number of number of private dwellings for each census tract. He then mapped the resulting ratios for each census tract.

Higher ratios correspond to darker census tracts. Theoretically, the darker the census tract, the more likely you are to run into trick-or-treaters.

Here are some of the GTA's high-traffic trick-or-treat spots:

  • Rosedale.
  • Cabbagetown.
  • Mississauga Road from King Street to Dixie Road.
  • Unionville.
  • Deercreek.

The map isn't necessarily an exact reflection of the concentration of trick-or-treaters in your area. That's because the most recent census data available to von Bergmann was from 2011.

"Birth rates are pretty constant," he says, however. "The age distribution overall doesn't change that much over the course of four years."

But you may want to pick up some extra treats before tomorrow night to hedge your bets if you don't want to disappoint.
