    Description of Gauge

    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?

Life expectancy is a summary mortality measure often used to describe the overall health status of a population.

How Are We Doing?

Life expectancy was slowly increasing among all racial and ethnic groups as well as among both males and females until 2015. Small declines in overall life expectancy were experienced the following three years before again increasing slightly in 2019. The COVID-19 pandemic in 2020 caused average life expectancy (ALE) among all New Jersey residents to decline 3 years. The impact on ALE was not the same among different groups. Between 2019 and 2020, ALE declined by 7.7 years among Hispanics, 6.1 years among Asians, 4.7 years among Blacks, and 1.7 years among Whites. ALE among males declined 3.3 years while the decline among females was 2.4 years. As of 2020, the average life expectancy among New Jersey residents was 77.7 years. Life expectancy among females (80.7 years) was six years greater than among males (74.8). Among New Jersey residents, life expectancy is highest among Asians (86.1 years), followed by Hispanics and Whites (both 78.4), and Blacks (72.2). By county, estimates range from 72.3 years in Salem to 82.4 years in Hunterdon.


Life expectancy from birth is very sensitive to infant and child mortality. Life expectancy from age 65 is less sensitive to infant and child mortality than life expectancy from birth and is thought to better represent overall adult health status. In NJSHAD, life expectancy is calculated using a method developed by CL Chiang. For more information on calculation of life expectancy in NJSHAD, please visit the [ life expectancy documentation page].
