Despite the growing recognition of the importance of youth in the world today, little is known about the current state of youth development, and measuring youth well-being remains a challenge, the World Youth Development Index. (YDI), prepared by the Commonwealth Secretariat/Youth Division, has the status of a set of indicators that measure progress in youth development in 183 States, including 49 out of 52 Commonwealth States and guided by the Commonwealth’s definition of youth as persons between the ages of 15 and 29.

The index aims to assist Governments in identifying specific areas of evidence-based policies and programs to improve the status of youth in development and political participation. The index is calculated using five main areas: levels of education, health, welfare, employment, opportunities, civic participation, and political participation.
