About 172 million US consumers plan to celebrate Halloween this year, spending an average of $86.27 per person on candy, costumes, cards and decorations for a total of $8.8 billion, according to a survey from NRF and Prosper Insights & Analytics. "Spending hasn't changed much over the past few years, but we are seeing a noticeable increase in consumers whose Halloween purchases are inspired by their friends, neighbors and even celebrities on social media," NRF President and CEO Matthew Shay said.
