Global Youth Development Index and Report 2016

The YDI is a composite index of 18 indicators that collectively measure multi-dimensional progress on youth development in 183 countries, including 49 of the 53 Commonwealth countries. It has five domains measuring levels of education, health and well-being, employment and opportunity, political participation and civic participation for young people. The YDI is guided by the Commonwealth definition of youth as people between the ages of 15 and 29, while recognising that some countries and international institutions define youth differently.
