The 2023 March of Dimes Report Card highlights key indicators to describe the current state of maternal and infant health. We continue to provide updated rates and grades for preterm birth and data on infant mortality and maternal health. New this year is the inclusion of maternal mortality, leading causes of infant death, and data describing selected risk factors for preterm birth. Indicators by maternal race/ethnicity are included to call attention to the need for addressing racism in our systems and communities in order to eliminate health disparities. Detailed analyses of these measures inform the development of policies and programs that move us towards improving health for birthing people and the millions of babies born each year in the U.S., D.C. and Puerto Rico. The Report Card presents policies like Medicaid extension and programs like Maternal Mortality Review Committees, which can help to achieve equity in maternal and infant health outcomes.

The preterm birth grade was D+ in 2022; the worst grades occurred in the southern region of the U.S.
