Figure 8. Expected relationship between cause-specific maternal mortality ratio (MMR; number of livebirths per 100 000 livebirths) and SDI (left) and proportion of maternal deaths due to each underlying cause and SDI (right).

Figure 8

These stacked curves represent the average relation between SDI and each cause of maternal mortality observed across all geographies over the time period 1990–2015. In each figure, the y axis goes from lowest SDI up to highest SDI. To the left of the midline are maternal mortality ratios (MMR; number of deaths per 100 000 livebirths), and the right-hand side shows the proportion of the total in order to highlight the different cause pattern in high SDI locations. SDI=Socio-demographic index.
