Under five mortality rates in each region at baseline and universal coverage. **. **Geographical GINI and the slope of inequality: The geographical GINI indexes are determined by the slope of inequality in Fig. 3 (dotted lines) and by the size of the regions. Since the size variable remains the same before and after scale-up, the geographical GINI index will increase from one scenario to another if the slope of the inequality increases, as illustrated in the comparison between baseline coverage and universal coverage. Conversely, the GINI index would decrease if the slope of inequality decreased
