Figure 5. Co-evolution of maternal mortality ratio (MMR; number of livebirths per 100 000 livebirths) with SDI globally and for GBD regions, 1990–2015.
Coloured lines show global and region values for MMR. Each point in a line represents one year starting at 1990 and ending at 2015. In all regions, SDI has increased over time so progress in SDI is associated with points further to the right and later years for a given region. The black lines indicate expected trajectories for each geography expected on the basis of SDI alone. SDI=Socio-demographic Index.
