2020s teen
These kids were children in the 2010s, and were adolescents in the 2020s. Many of them probably like doing things like Tiktok, Instagram, PlayStation 5 gaming, and a lot of other modern-day technology-based things.
I was born in 2005, so I suppose I can be called a late 2010s/early 2020s teen. I certainly do remember the things stated above. However, I was only engaged into a few of them - the other things never really got my interest.
