    Description of the Gauge

    This graphic is based on the county data to the left. It compares the county value of this indicator to the state overall value.
    • Excellent = The county's value on this indicator is BETTER than the state value, and the difference IS statistically significant.
    • Watch = The county's value is BETTER than state value, but the difference IS NOT statistically significant.
    • Improvement Needed = The county's value on this indicator is WORSE than the state value, but the difference IS NOT statistically significant.
    • Reason for Concern = The county's value on this indicator is WORSE than the state value, and the difference IS statistically significant.

    The county value is considered statistically significantly different from the state value if the state value is outside the range of the county's 95% confidence interval. If the county's data or 95% confidence interval information is not available, a blank gauge image will be displayed with the message, "missing information."
    NOTE: The labels used on the gauge graphic are meant to describe the county's status in plain language. The placement of the gauge needle is based solely on the statistical difference between the county and state values. When selecting priority health issues to work on, a county should take into account additional factors such as how much improvement could be made, the U.S. value, the statistical stability of the county number, the severity of the health condition, and whether the difference is clinically significant.

Why Is This Important?

Postneonatal mortality is an important indicator of infant and maternal health status and medical care (pre and post delivery), as well as a measure of how certain behavioral factors affect infant health.

How Are We Doing?

One-third of infant deaths occur in the postneonatal period. The postneonatal mortality rate among children of Black mothers is three to six times that of other racial/ethnic groups. The leading causes of postneonatal mortality are sudden infant death syndrome (SIDS) and congenital anomalies (birth defects). These two causes account for about 40% of postneonatal deaths.

What Is Being Done?

The [ Division of Family Health Services] in the New Jersey Department of Health administers several programs aimed at improving children's health, including reducing infant mortality. In an effort to improve health outcomes among Black infants and mothers in New Jersey, six maternal and child health agencies across the state were awarded $4.3 million in grant funding in July, 2018, as part of the Department of Health's "[ Healthy Women, Healthy Families]" initiative. In addition to these funds, the Department devoted $450,000 to implement a doula pilot program in municipalities with high Black infant mortality rates.

Healthy People Objective MICH-1.5:

Postneonatal deaths (between 28 days and 1 year)
U.S. Target: 2.0 postneonatal deaths per 1,000 live births


** The number of deaths is too small to calculate a reliable rate.

Measure Description for Postneonatal Mortality Rate

Definition: Rate of death occurring from 28 days to 364 days of age in a given year per 1,000 live births in the same year Infant mortality is death within the first year of life. This is divided into two components: death before the 28th day of life is neonatal mortality; death between 28 days and one year is postneonatal mortality.
Numerator: Number of resident deaths occurring from 28 days to 364 days of age in a given year
Denominator: Number of live births to resident mothers in the same year
