U.S. Infant Mortality Hits Record Low of Under 5.4 per 1,000 Births in 2025 but Remains Nearly Double Peer-Nation Rates

The CDC's late-May 2026 release of 2025 provisional figures and its detailed 2024 analysis document declines in both neonatal and post-neonatal mortality, a drop in full-term deaths, and continued racial gaps with Black infants dying at more than twice the rate of White, Hispanic, and Asian infants. Mississippi recorded 9.65 deaths per 1,000 while New Hampshire reported under 3.0. These patterns align with known drivers including prenatal-care access, poverty concentration, and state policy differences rather than isolated medical events.

International comparisons published in 2025 showed the 2022 U.S. spike reached nearly twice the rate of comparable high-income democracies; the subsequent decline coincides with expanded maternal RSV vaccination and infant nirsevimab use plus sustained safe-sleep messaging that reduced SIDS. Yet absolute numbers remain elevated because structural factors—Medicaid expansion gaps, maternity-care deserts, and cumulative social determinants—persist across multiple birth cohorts.

Further progress requires linking vital-statistics improvements to measurable expansions in continuous insurance coverage and regional perinatal quality collaboratives. Without those, year-to-year fluctuations may stall near the current plateau rather than converge on peer-nation benchmarks.

Next surveillance must include 2026 final files disaggregated by maternal nativity, detailed cause-of-death coding, and linkage to prenatal-visit timing to test whether recent interventions scale or plateau.
