2016 Global Youth Development Index: Results and Analysis 2.4  Analysis by YDI domain The YDI is intended to provide a rounded view of the state of youth development at national and international levels, and to serve as an evidence base that can help the broader human development framework become more seamlessly aligned with the needs and priorities of young people. It is therefore important to note the YDI weighting scheme when interpreting domain results. Similar to the methodology in the HDI, the YDI depends largely on a set of three primary indicators: literacy rates, youth mortality and youth NEET. Primary indicators are weighted more heavily in the Index, so they have more of an impact on overall YDI scores than other indicators, in some cases giving countries an Youth development is as much about progress made in each of the five domains as it is about the overall YDI score. It is important to study the relationship between the domains in order to understand the broader environment for youth development. Analysing the relative performance of a country in any of the YDI domains can help deepen understanding of the positive or negative determinants of youth development. This section presents the progress made in each of the YDI domains and lists the ten highest and lowest-ranked countries in each domain.
