I feel like the 15% that do not use TikTok are more likely to be from lower class or impoverished families. Likely because they have limited access to smartphones or electronics of their own.

I’m sure there are “elite” families who strictly forbid their children from using social media, but I suspect this population is very low. In my own anecdotal experience, the most affluent teens had the most access to drugs and things our parents forbade us from having.
