The rate of preterm births remains alarmingly high in the U.S., according to the latest March of Dimes Report Card.
The figure was around 10.4% as of 2022 — just a 1% decline from 2021, when the preterm rate was at its highest in a decade.
Every year, the March of Dimes assigns each U.S. state a preterm birth “grade,” based on the share of babies born before 37 weeks’ gestation.
