Answer:

The first is the improvement that is likely to have occurred without the MDGs and is calculated by extrapolating to the entire period 1990-2015 the pre-MDG trend of 1990-2000. The second part is the improvement that may be attributed to the MDGs and is calculated as the actual improvement during 1990-2015 minus the part based on pre-MDG factors. The contributions are estimated for the world and six geographical regions. Apart from the huge diversity across the indicators and the regions, the exercise indicates two main points. First, MDGs did make a positive contribution to the improvement in almost all cases and it is not true that the MDGs contributed little. Second, however, the improvement attributable to the pre-MDG factors dominates contribution of the MDGs. Relative to the Sustainable Development Goals (SDGs), the study indicates that attainment of the SDG targets for access to safe water and under-5 mortality at the global level appears likely, but attainment of the targets for poverty rate, maternal mortality, and access to sanitation seems unlikely.
