Youth

Youth is a stage of human development that bridges childhood and adulthood. The term covers a broad range of ages and its precise meaning varies by country, culture, and context. International organizations commonly classify adolescence and youth as roughly the period between early teens and mid-twenties; for example, the United Nations often defines youth as ages 15 to 24, while other programs extend this to 15 to 29. Some health and education frameworks separate younger adolescents (10 to 14) from older youths (15 to 24) or 25.

During youth, individuals undergo rapid physical, cognitive, and social changes. Identity formation, increasing autonomy, and peer influence are common. Education and skill development are central to outcomes, with higher participation linked to better health, employment, and civic engagement. Mental health concerns, substance use, and risky sexual behavior can emerge; access to comprehensive health services, supportive families, and safe environments mitigate risks.

Social roles and rights for youth include opportunities for formal education, vocational training, and meaningful participation in communities. Digital life and media literacy shape information access, political awareness, and social networks. Inequities related to gender, socioeconomic status, disability, and geography can affect outcomes, making targeted programs and inclusive policies important.

Policy and research emphasize youth development, prevention, and inclusion. Programs aim to reduce unemployment, improve health services, promote mental well-being, and provide pathways to lifelong learning and economic participation. Because definitions of youth vary, analyses and interventions often tailor age ranges to local legal and cultural contexts.
