Facebook doesn’t Like math

Facebook claims it can reach more young people than actually exist in the U.S., which could hurt its push to compete for TV advertising budgets, Pivotal Research Group analyst Brian Wieser wrote in a note to clients. Facebook’s Ads Manager claims it has potential access to 41 million 18- to 24-year-olds in the U.S., Wieser wrote. But there’s a teensy problem: Wieser said there are only 31 million people in that age category, according to the census. The gap, which also exists for other age ranges, doesn’t seem to be widely known by ad agencies, Wieser said.
