Most likely there is in nicer schools. There are social groups around swim competitive clubs, ski race teams, hockey teams, ball hockey, summer long duration live in camps etc.

In many ways hanging out with kids who are banned from social media is hanging out with kids from a pretty exclusive club. This is why unless you homeschool it is REALLY worth it to put your kids into school where parents are from a similar group as you are.

I have a daughter who's 11 years of age and has plenty of friends at school. She doesn't have an instagram account and hasn't asked me to get her a device so that she's able to create an account and log on. So I really doubt there aren't social groups in school and other settings where instagram isn't a primary focus.
