2021 March of Dimes Report Card

March of Dimes presents the 2021 report card for the U.S., each state, Washington D.C. and Puerto Rico. The report card has evolved over the years and now focuses on both mom and baby health topics.

The report card maintains its most influential aspect of a grade on preterm birth for the nation and each state. Grades for the 2021 report cards utilize the 2020 natality data from National Center for Health Statistics.

The 2021 Mom and Baby Report Card contain a mixture of continued and new data points. As in previous years, the Report Card will continue to report on preterm birth rate, assign grades, preterm birth rate by race/ethnicity and preterm birth rates for the city with the greatest number of births. We have also continued to track, inadequate prenatal care, Medicaid extension and expansion, MMRCs and PQC development.

New this year is a specific focus on maternal health indicators on the second page of the Report Card. The addition of a measure towards health equity is the Social Vulnerability Index, providing geographic analysis by county for each state. Additional new measures include, low-risk Cesarean births and policy tracking for midwifery and doula care in states. We have also included an additional QR code at the top of the Report Card that will take you to our webpage with multiple links to other state data and Report Card resources.

In 2021, March of Dimes is also providing a Supplemental Report Card to share data about race and ethnicity. The following data in the Supplemental Report is disaggregated by race and ethnicity: infant mortality rate, low-risk Cesarean birth rate, inadequate prenatal care, live births and preterm birth. The preterm birth rate by county is also available. The Supplemental Reports are available for each state and the District of Columbia.
