Teen

Teen, short for teenager, refers to a person in the second decade of life, typically aged 13 to 19 years old. The term derives from the numerals thirteen through nineteen, all of which end with the suffix -teen.

Adolescence is a period of rapid physical, cognitive, and social change. Puberty brings physical growth and sexual maturation; brain development continues into early adulthood, influencing decision making, risk assessment, and identity formation. Social relationships, school, and peer groups take on growing importance, and many teens begin to assume greater independence.

Education and health: Most teens attend secondary education or equivalent programs. Health concerns during adolescence include mental health, sleep, nutrition, sexual health, and substance use. Access to confidential health services and supportive environments can reduce risk behaviors. Protective factors include stable family support, positive school climate, and involvement in activities.

Legal and cultural context: Rights and responsibilities for teens vary by country and jurisdiction. Age thresholds commonly determine eligibility for driving, part-time work, consent, and voting. Cultural expectations of teen roles and milestones differ, including rites of passage, education paths, and social norms. In media, teenagers are often depicted with stereotypes, though experiences are diverse.

Teenagers represent a diverse and transitional population with varying needs in education, health, and social development.
