Trick-or-treating

UNICEF

"'Trick-or-Treat for UNICEF" has become a common sight during Halloween in North America. Started as a local event in a Philadelphia suburb in 1950, and expanded nationally in 1952, the program involves the distribution of small boxes by schools to trick-or-treaters, in which they can solicit small change donations from the houses they visit. It is estimated that children have collected more than $119 million (US) for UNICEF since its inception. In 2006, UNICEF discontinued their Halloween collection boxes in parts of the world, citing safety and administrative concerns
