Infant Mortality Dashboard

NOTES:

Infant mortality rates refer to the number of deaths under age 1 year per 1,000 live births. The neonatal mortality rate refers to the number of deaths of infants aged 0–27 days per 1,000 live births. The postneonatal mortality rate refers to the number of deaths of infants aged 28 days through 11 months per 1,000 live births.

Rates for "12 months ending with quarter" (also called moving average rate) are the average rates for the 12 months that end with the quarter on the horizontal (time) axis. Estimates for the 12-month period ending with a specific quarter include all seasons of the year and, thus, are insensitive to seasonality.

A hollow circle indicates that estimates for the most recent quarter are significantly different from the same quarter of the previous year (p < 0.05); these estimates are also flagged in the data table with an asterisk (*).

SOURCE: NCHS, National Vital Statistics System. Estimates for 2023 are based on provisional infant death and birth data. Estimates for 2022 are based on final infant death and birth data (available from: http://wonder.cdc.gov/).

NOTES:

† Estimate should be interpreted with caution. See Technical Notes: Accuracy of estimates.

Infant mortality rates are presented as deaths per 100,000 live births. The five leading causes of infant mortality in 2019, 2020 and 2021 were Congenital malformations, deformations and chromosomal abnormalities (Q00–Q99); Disorders related to short gestation and low birth weight, not elsewhere classified (P07); Newborn affected by maternal complications of pregnancy (P01); Sudden infant death syndrome (SIDS) (R95); and unintentional injuries (V01–X59). The order of the top five causes may vary by year.
