Black-White Infant Mortality Gap Widened Since 2020
A study of 58 million births found that rising rates of unexpected infant deaths have deepened racial disparities.
Updated on Sept. 24, 2026 in Babies

The mortality gap between Black and white infants in the United States began to widen in 2020. Sudden unexpected infant death now accounts for more than one-third of this persistent disparity.
Why it matters
Rising sudden unexpected infant death rates among Black infants, potentially exacerbated by pandemic-era economic pressures and respiratory infection trends, have significantly increased the mortality gap. This shift underscores a growing concern in national public health and infant care.
A study analyzing nearly 58 million U.S. live births from 2003 to 2024 linked infant mortality disparities to rising rates of sudden unexpected infant death. These findings indicate that the mortality rate for infants born to Black mothers remains double that of white mothers.
The players
JAMA Network Open
A peer-reviewed medical journal that publishes original research on clinical care and public health.
University of Colorado Boulder
A public research university where the investigators conducting this study are affiliated.
The details
Researchers utilized birth and death certificates to group infants into seven categories based on gestational age to identify mortality trends. The analysis highlights that sudden unexpected infant death is a primary driver of the widening gap. While specific mechanisms are complex, investigators suggest that broader systemic factors, including the long-term economic consequences of the pandemic and changing patterns in respiratory infections, may play a critical role in these outcomes.

Health Landscape
This study aligns with the JAMA Network Open research program by providing updated data on the persistent and widening racial disparities in U.S. infant mortality. The findings mark a departure from previous trends by identifying how sudden unexpected infant death specifically influences these gaps.
These findings underscore the importance of discussing current infant safety and mortality risks with your pediatrician during routine prenatal and postnatal visits. Families should remain informed about the latest pediatric guidance regarding sleep environments and respiratory health precautions for newborns.
The takeaway
This data highlights a significant widening of the infant mortality gap linked to sudden unexpected infant death since 2020. Families are encouraged to consult with their healthcare provider to review updated infant safety practices and address any specific concerns regarding their child's health.
