any person age 13 or over - around 20. So basically high school. these days, they are very material and cover up their real emotions. these people are into dating and care about how they dress. they are too old for disney channel, but too busy to watch the news. life is hard. they are still figuring things out.
Teen: wow. great. still not caring.
Tween: like OMg I CannOT believe This is happening to me!!!! the world must like hate me or something! :(
Adult: Oh dear! I will take action on this right away!

Some people (what I can only speculate as children) ignorantly claim 18/19 year olds are NOT teens, and label them as adults yet fail to acknowledge teen isn't a title, it's an age categorization that's upto a government or a countries legal system to decide what they and what they do not proclaim as adults, some countries chose to label their citizens as adults as early as 15, some as late at 21, In accordance of Jewish law a boy become a man ages 13. WHEN you hit your second decade of life (20+), you're known as a 20-something, before that period, you're a TEEN.
Teen is not a title, it's an age.
SIX-TEEN.
SEVEN-TEEN.
EIGHT-TEEN.
NINE-TEEN.

American: An eighteen year old is not a teenager! It's an adult!

Scottish: Well, in Scotland the age of majority is 16, so you're both an ADULT AND a TEEN.

Scientist: People in their late teens (17-19), are still biologically adolescent, however lawfully it's for a state to decide at which age their citizens are to be held accountable for their actions and themselves.
