"Trick-or-Treat for UNICEF" is a fundraising program to support UNICEF, a United Nations Programme that provides humanitarian aid to children in developing countries. Started as a local event in a Northeast Philadelphia neighborhood in 1950 and expanded nationally in 1952, the program involves the distribution of small boxes by schools (or in modern times, corporate sponsors like Hallmark, at their licensed stores) 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 $118 million for UNICEF since its inception. In Canada, in 2006, UNICEF decided to discontinue their Halloween collection boxes, citing safety and administrative concerns; after consultation with schools, they instead redesigned the program.
