Adolescence is the period of psychological and social transition between childhood and adulthood.

As a transitional stage of human development it represents the period of time during which a juvenile matures into adulthood.

The ages of adolescence vary by culture.

The World Health Organization (WHO) defines adolescence as the period of life between 10 and 19 years of age.

In contrast, in the United States, adolescence is generally considered to begin somewhere between ages 12 and 14, and end at 19 or 20.
