This report, published by the United Nations (UN) Maternal Mortality Estimation Inter-Agency Group (MMEIG), presents internationally comparable global, regional and country-level estimates and trends for maternal mortality between 2000 and 2017. Countries and territories included in the analyses are WHO Member States with populations over 100 000, plus two territories (Puerto Rico, and the West Bank and Gaza Strip). The results described in this report include the first available estimates for maternal mortality in the SDG reporting period; but since two years (2016 and 2017) is not sufficient to show trends, estimates have been developed and presented covering the period 2000 to 2017.
