- Definition: Number of deaths among children under age 1 per 1,000 live births (e.g., in 2013-2015, there were 4.5 infant deaths per 1,000 live births in California).
- Data Source: California Dept. of Public Health, Death Statistical Master Files; National Center for Health Statistics, Linked Birth / Infant Death Records (Sept. 2017).
- Footnote: Data are presented as rates over three-year periods. The notation S refers to data that have been suppressed because there were fewer than 20 infant deaths. N/A means that data are not available.
- Measures of Infant Mortality on Kidsdata.org
Kidsdata.org provides the following measures of infant mortality:
- Infant mortality rate, as three-year averages
- Infant mortality rate by leading cause of death,* as three-year averages
- Infant mortality rate by mother's race/ethnicity, as five-year averages
Single-year data on the number and rate of infant deaths in California and the U.S. also are available.*Cause of death data are provided for the five leading causes of infant death in California overall. The leading causes of infant death statewide are very similar to the leading causes locally and nationally.
- Infant Mortality
- Low Birthweight and Preterm Births
- Prenatal Care
- Teen Births
- Why This Topic Is Important
Infant mortality is a key measure of a nation's health, as it reflects socioeconomic conditions, public health practices, maternal health, and access to high-quality medical care, among other factors (1, 2). Major causes of infant mortality include congenital malformations or abnormalities (birth defects), disorders relating to short gestation and low birthweight, maternal complications of pregnancy, and Sudden Infant Death Syndrome (3). Reducing infant mortality requires wide-ranging approaches that improve primary care prior to pregnancy, prenatal and well-baby preventive care, specialty care for preterm infants and those with health conditions, breastfeeding support, and immunizations, along with empowered communities creating safe, healthy environments for all families (1).
Although the U.S. infant mortality rate has declined in recent decades, it remains higher than rates in most other developed countries (1, 2). The infant mortality rate among African American/black mothers is particularly high—more than double the rate for white, Latino, and Asian/Pacific Islander groups, both nationally and in California (3, 4).Find more information and research on infant mortality in kidsdata.org's Research & Links section.

- How Children Are Faring
California's infant mortality rate declined by 37% between 1994 and 2015, from 7 infant deaths per 1,000 live births to 4.4 per 1,000, echoing national trends. At the county level, infant mortality rates range widely, from 2.8 (San Mateo) to 8.1 (Mendocino) among counties with data in 2013-15. Statewide, in 2013-15 and in previous years, the leading causes of infant death were birth defects and disorders related to preterm birth and low birthweight.
Disparities persist in infant mortality rates by race/ethnicity. Statewide, among groups with data in 2011-15, infants born to African American/black and multiracial mothers died at rates of at least 9 per 1,000, whereas Asian/Pacific Islander and white mothers had infant mortality rates below 4 per 1,000.
- Policy Implications
Some of the leading causes of infant mortality (e.g., birth defects, preterm births, and Sudden Infant Death Syndrome (SIDS)) are preventable, and can be addressed through public policy. California currently promotes newborn screenings for potentially fatal birth defects, as they can help avert long-term health consequences, and even death, through early identification and treatment (1). Public and institutional policy also can address the risk and protective factors for SIDS and preterm births (2). Risk factors can be reduced through many different strategies, such as ensuring that women are in good health before conception, avoid smoking and substance use while pregnant, and forgo elective deliveries before 39 weeks gestation, as well as broader strategies that address social determinants of health (2, 3).
Policy and program options that could reduce infant mortality include:

Also see policy implications on kidsdata.org for Low Birthweight and Preterm Births and Prenatal Care.
- Supporting evidence-based, culturally-appropriate communication and social marketing strategies to help educate families about ways to promote infant health, including family planning, breastfeeding, immunizations, smoking cessation, and safe sleep practices (2, 3)
- Ensuring that public education to prevent SIDS and other sleep-related infant deaths reaches a wide constellation of potential caregivers for infants; key recommendations include avoiding sleeping on the stomach, overly soft sleeping surfaces and loose bedding, co-sleeping, and smoking during pregnancy (2, 4)
- Sustaining funding for substance use screening among pregnant women and for treatment specifically designed for pregnant women who use alcohol or drugs (2)
- Supporting education and systems change to reduce the number of elective deliveries before 39 weeks (2, 3)
- Promoting research and strategies aimed at reducing the rates of preterm labor and delivery (5)
- Increasing public education and ensuring funding for prenatal and newborn screening services, as early identification can reduce the risk for infant death, brain damage, and serious illness (1)
- Continuing efforts to ensure that all women and infants, including those with special health care needs, receive quality medical care that is safe, timely, effective, efficient, and patient-centered (2)
- Supporting a comprehensive approach to women's health—including integration of reproductive planning into women's routine health care—as good health before conception can improve pregnancy outcomes; this should include addressing mental/behavioral health and social support needs, as well as increasing the interval between pregnancies to at least 12 months (2, 6)
- Continuing to address the underlying causes of infant mortality by focusing on social determinants of health, for example, investing in under-resourced communities and efforts to ameliorate the effects of poverty on families during childbearing years (2)
- Supporting ongoing efforts to improve data systems for measuring health care access, quality, and outcomes for women and infants, as timely and accurate data is critical for informing policy and program decisions (2)
- Promoting collaboration across agencies and sectors at the local, state, and national levels, to combine resources and expertise toward the common goal of reducing infant mortality (2)
