The holiday became increasingly youth-oriented thanks to the 1950s baby boom.
By the time the 1950s hit, American communities had succeeded in removing the taboo from Halloween – including vandalism, which had previously run rampant on October 31.
The baby boom of the ’50s also made the holiday more family-oriented, and Halloween parties began to move to school classrooms and homes. Trick-or-treating was also revived around this time and has been steadily practiced since.
