How many middle schools in the US have a gymnastics team?

There's no central, publicly accessible database tracking the existence of gymnastics teams at every US middle school. Therefore, it's impossible to give a precise number. The number varies greatly depending on factors like:

* School size and resources: Larger, wealthier schools are more likely to have the resources to fund and staff a gymnastics team.

* Geographic location: Gymnastics may be more prevalent in certain regions than others.

* School district policies: Some districts might actively promote extracurricular activities like gymnastics, while others might not.

To get an estimate would require a massive, nationwide survey of middle schools, which hasn't been conducted.
