The purpose of the global indicators, which will be reported on with one national aggregate per indicator, is to broadly track progress towards the Goals and targets at the global level. They are also useful for countries to communicate their current situation, both to the international community to raise awareness of challenges and needs, and to the own population to show that progress is being made.
To be useful for policy- and decision-making at national and sub-national levels, the global indicators need to be disaggregated and put into a context.
