A teen is a person aged 13 - 19, because of the the number ending in "teen", this age group is popularized because coincidentally it is also when the biggest amounts of changes occur in a person.

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 aged 13. WHEN you hit your next 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, therefore it's an age group, not a title.

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.

A group of people which keeps getting worse as generations go on. This generation's teens listen to pretty crappy music like 50 Cent and Good Charlotte. They also tend to have no minds of their own. They're getting fatter and fatter and fatter... Yeah, there are some decent teenagers... Not enough though.
