Infant Mortality in the United States, 2024: Data From the Period Linked Birth/Infant Death File
Summary
In 2024, the U.S. infant mortality rate remained stable at 5.52 deaths per 1,000 live births. The postneonatal mortality rate saw a decline, while sudden infant death syndrome rates also decreased among leading causes of infant death.
Area of Science:
- Public Health
- Biostatistics
- Epidemiology
Background:
- Infant mortality remains a critical public health indicator.
- Understanding trends and disparities in infant mortality is crucial for targeted interventions.
Purpose of the Study:
- To present final 2024 infant mortality statistics in the United States.
- To examine trends in infant mortality by various demographic and clinical factors.
Main Methods:
- Utilized the 2024 period linked birth/infant death file, based on birth and death certificates from all 50 states and D.C.
- Conducted descriptive tabulations and interpretations of infant deaths and mortality rates.
- Analyzed data by age at death, maternal race/Hispanic origin, maternal age, gestational age, leading causes of death, and state of residence.
Main Results:
- The U.S. infant mortality rate was 5.52 per 1,000 live births in 2024, similar to 2023.
- The postneonatal mortality rate declined by 4.6% from 2023 to 2024.
- Infants of Black non-Hispanic women had the highest mortality rate (10.98), while Asian non-Hispanic women had the lowest (3.72).
- Mortality rates for sudden infant death syndrome decreased compared to 2023.
Conclusions:
- Overall U.S. infant mortality rates remained stable in 2024.
- Significant disparities in infant mortality persist across racial and Hispanic origin groups.
- Declines in postneonatal mortality and SIDS rates are noted, warranting further investigation.

01:22Life Tables
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...
01:22Applications of Life Tables
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...
01:20Actuarial Approach
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.

01:29Drug Dosing: Infants and Children
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
01:18Introduction To Survival Analysis
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time until a...

01:29Life Histories
Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off is represented by two primary reproductive strategies; K-strategists produce few offspring but provide substantial parental support, whereas r-strategists produce much progeny that receives little care. These strategies are related to an organism’s survival likelihood across its lifespan, which is represented by a survivorship curve. Three general types of...
