The 2025 March of Dimes Report Card highlights the many factors contributing to maternal and infant mortality and morbidity. Since 2008, March of Dimes has released this report to educate and advocate for better mom and baby outcomes across the US,  including Nevada, Washington, D.C., and Puerto Rico. For the fourth consecutive year, the United States earned a D+ grade for preterm birth, marking the longest stretch of the lowest grade in Report Card history. Behind that static letter grade lies a troubling truth: our nation remains stuck in a maternal and infant health crisis. In 2024, nearly 380,000 babies were born preterm—1 in 10 births—placing the US among the highest rates in developed nations. Progress is not reaching the families who need it most.
