The lagging attendance has much to do with the changing demographics of the state and nation, cultural factors and declining youth participation.
There’s a lot more student mobility than there was three to four decades ago. Many of those who once filled the stands have aged out. Odds are their grandkids don’t attend the same school as their kids did.
There are also cultural factors tied to the decline. Within some cultures, watching kids play sports means considerably less. My buddy is a project manager at a large, diverse corporation in suburban Columbus. He gets a different reaction to telling his suburban coworkers he’s going games than he does to his neighbors in a rural part of the state. We are one of a very few nations that host interscholastic competition.
Declining youth participation is probably the biggest reason I don’t see the decline correcting itself. Fewer kids playing at a younger age translates to fewer paying customers years later.
For these reasons, I’ve learned to embrace school sports for what they are, and worry less about what they were and where they’re going.
