    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?

Demographics are an important determinant of health and well-being.

How Are We Doing?

New Jersey is recognized as one of the most diverse states in the nation: 21.5% of its residents are Hispanic, 12.3% are Black, and 9.9% are Asian. Nearly one-quarter of residents are foreign-born and more than one million (12.1%) residents do not speak English very well. The median age of residents is 40.3 years, 50% of those aged 15 and older are married, 4% of those 18 and older are veterans, and one-tenth of the civilian noninstitutionalized population has a disability. Median per capita income in New Jersey is $47,338. The unemployment rate among those age 16 and older is 8.1%, 10.2% of residents live below the poverty level, and 7.2% have no health insurance. Among those aged 25 and older, 91% have graduated high school and 43% have a bachelor's degree or higher. Among those aged 25 and over and in poverty, 22.4% did not finish high school. Median earnings for employed persons aged 25 and over without a high school diploma or equivalent were $28,336 compared to $37,180 for those with a diploma or GED, $46,071 for those with some college or an associate's degree, $71,258 with a bachelor's degree, and $94,788 with a graduate or professional degree. More than 95% of households have a computer and 92% have a broadband internet subscription.


The Gini Index is a summary measure of income inequality. The Gini coefficient incorporates the detailed shares data into a single statistic, which summarizes the dispersion of income across the entire income distribution. The Gini coefficient ranges from 0, indicating perfect equality (where everyone receives an equal share), to 1, perfect inequality (where only one recipient or group of recipients receives all the income). The Gini is based on the difference between the Lorenz curve (the observed cumulative income distribution) and the notion of a perfectly equal income distribution. More information: []
