Infant Mortality Update

PeriStats has been updated with the most current data on infant mortality rates to include rates for the years 2014-2018. These updates also include the most current data on age at infant death, percent by age at death, percent by race/ethnicity and cause of infant death. The data has been updated through the National Center for Health Statistics (NCHS) at the Center for Disease Control (CDC). Infant mortality data is available based on maternal age, by race and ethnicity. Information is given on age of infant death (neonatal or post neonatal) and can be viewed in a variety of formats including pie charts, bar graphs and maps.

Infant mortality rates are defined as death of an infant before one year of age and are reported per 1,000 live births. These rates can also be thought of as the risk of death in the first year of life and can serve as one way to understand the health of the whole community. The neonatal period is defined as babies in the first four weeks of life and post-neonatal is the period after the first month of life up to the end of the first year of life.
