Sustainable Development Goals - 17 Goals to Transform our World

Maternal mortality in the UK is measured as a rate per 100,000 maternities (defined as women who give birth to a live infant or a stillborn infant at 24 weeks or greater gestation), and not a ratio per 100,000 live births, in order to provide a closer approximation of the risk associated with pregnancy.

Maternal deaths are identified through a variety of sources by the MBRRACE-UK collaboration at the NPEU, University of Oxford. Further details of ascertainment methods, additional disaggregations, details of causes of death and recommendations for improving care can be found in the MBRRACE-UK Saving Lives, Improving Mothers’ Care reports.

The maternal mortality ratio for the UK, following the UN specification, can also be found in the MBRRACE-UK reports using the link above.

Unit of measurement

Rate per 100,000 maternities


A maternal death is the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and the site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes. IMD - Index of Multiple Deprivation.

Available disaggregations

Maternal mortality rate = (Number of maternal mortalities / total number maternities) * 100,000

This indicator is being used as an approximation of the UN SDG Indicator. Where possible, we will work to identify or develop UK data to meet the global indicator specification. This indicator has been identified in collaboration with topic experts.
