Trick-or-treat map shows how many kids live in your neighbourhood

A software developer has come up with a high-tech solution to help people figure out how much Halloween candy to buy.

Jens von Bergmann of Vancouver used census-mapping software to create the Trick-or-Treat Onslaught map, which breaks down the number of children aged five to 14 by geographical area.

The data used is from the 2011 census, but von Bergmann is satisfied it will serve the purpose.

You can use the map to check our your own neighbourhood.
