Demographic of Grime?

I just want to know what age or group of people are actively listening to Grime? I'm 18 but because I grew up on Garage (Dad's a garage producer), the transition from Garage to Grime was a minor, and now it's basically all I listen to. But all my boy's know about the Grime scene, but mostly listen to UK Drill and Rap. Wanted some thoughts?
