I disagree with a few of your terms:

10-12 are preteens, tweens are those in their twenties- hence the “tw”

These used to be simply considered adults, but now are culturally apart so have their own categories. Also, I would put young adult as younger than you did- say 18-21- overlapping some of the other categories.
