In 1999, the General Assembly endorsed the recommendation made by the World Conference of Ministers Responsible for Youth (Lisbon, 8-12 August 1998) that 12 August be declared International Youth Day. International Youth Day gives an opportunity to celebrate and mainstream young peoples’ voices, actions and initiatives, as well as their meaningful, universal and equitable engagement. Youth There is no universally agreed international definition of the youth age group. For statistical purposes, however, the United Nations - without prejudice to any other definitions made by Member States - defines "youth" as those persons between the ages of 15 and 24 years. This definition, which arose in the context of preparations for the International Youth Year (1985) (see A/36/215), was endorsed by the General Assembly in its resolution 36/28 of 1981. This statistically oriented definition of youth, in turn, entails that children are considered those persons under the age of 14. Worthy of note, however, is that Article 1 of the United Nations Convention on the Rights of the Child defines ‘children’ as persons up to the age of 18. At the time, it was hoped that the Convention would provide protection and rights to as large an age-group as possible, especially as there was no similar document on the rights of youth. Many countries also draw the line on youth with regard to the age at which a person is given equal treatment under the law - often referred to as the "age of majority." This age is commonly 18 in many countries; so that once a person attains this age, he or she is considered to be an adult. Nonetheless, the operational definition and nuances of the term "youth" vary from country to country, depending on relative sociocultural, institutional, economic and political factors. Today, there are 1.2 billion young people aged 15 to 24 years, accounting for 16 per cent of the global population . By 2030 - the target date for the Sustainable Development Goals (SDGs) that make up the 2030 Agenda - the number of youth is projected to have grown by 7 per cent, to nearly 1.3 billion. 2025 Theme: Youth Localizing the SDGs The theme of International Youth Day (IYD) 2025, Local Youth Actions for the Sustainable Development Goals (SDGs) and Beyond, highlights the unique role of youth in translating global ambitions into community-driven realities. As development partners work to translate and implement the global goals within specific local contexts, aligning them with community needs while maintaining consistency with national and international commitments, young people are critical partners. They bring creativity, insight, and deep community ties that help bridge the gap between policy and practice. With over 65 per cent of SDG targets linked to local governance, youth engagement is not a luxury - it is a necessity. This year’s IYD will also underscore the essential role of local and regional governments. Being the closest to the communities they serve, they are uniquely positioned to create inclusive policy environments, allocate resources, and establish mechanisms for youth participation in local planning and decision-making. By integrating youth priorities into local and regional strategies and fostering partnerships with youth organizations, authorities can collaborate with young people to transform their ideas into impactful solutions. When local governments provide spaces for innovation, mentorship, and civic engagement, they not only accelerate SDG implementation but also nurture future community leaders and changemakers. Did you know? Half of the people on our planet are 30 or younger, and this is expected to reach 57% by the end of 2030. Survey shows that 67% of people believe in a better future, with 15 to 17 year-olds being the most optimistic about this. By 2050, the people who are under 25 today will compose more than 90% of the prime-age workforce. 13% of the young labour force is unemployed. This number from 2023 marks the lowest rate in 15 years. Among children ages 10-19, 1 in 7 experience a mental disorder. Nearly 6 in 10 ten-year-old children in low- and middle-income countries cannot read and comprehend a simple paragraph. Source : UN
