I also have a great deal of trouble believing this survey and there's no indication of how they arrived at these numbers, beyond that it's a sample of some 4,000 people.

But I've read story after story in recent years indicating that many Millennials don't use or even own a radio. (Indeed, I recall one in which they were asked how to operate a radio and didn't know. I also remember I once asked a young nephew of mine in the Millennial age group if he'd ever heard of AM radio. He hadn't.) So I'm rather skeptical, as well.

Still, this company claims to have been in the survey biz for more than 25 years and they stand by their numbers.
