Middlesex County Public Health Profile Report
Age-Adjusted Death Rate: Deaths per 100,000 Standardized Population, 2020
Middlesex787.3 95% Confidence Interval(768.2 - 806.4)Description of the Confidence IntervalThe confidence interval indicates the range of probable true values for the level of risk in the community.
A value of "NA" (Not Available) will appear if the confidence interval was not published with the NJSHAD indicator data for this measure.
Middlesex Compared to State
Description of Gauge
Description of the GaugeThis graphic is based on the county data to the left. It compares the county value of this indicator to the state overall value.
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.
- 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.
Why Is This Important?Age-adjusted death rates are constructs that show what the level of mortality would be if no changes occurred in the age composition of the population from year to year. Age-adjusted death rates are better than crude death rates as indicators of relative risk when comparing mortality across geographic areas or between gender or racial/ethnic subgroups of the population that have different age compositions.
How Are We Doing?The age-adjusted death rate had been decreasing fairly steadily until the opioid crisis took hold in 2017. The decline resumed in 2018 and 2019 but the COVID-19 pandemic caused New Jersey's age-adjusted death rate to climb 26.7% between 2019 and 2020, reaching a level not seen in twenty years. Between 2019 and 2020, the age-adjusted death rate rose 70.1% among Hispanics, 50.8% among Asians, 39.5% among Blacks, and 17.4% among Whites. Despite the wide variation in these increases, the rate remained highest among Blacks, followed in order by Whites, Hispanics, and Asians. In 2020, the age-adjusted death rate among Blacks was 1.4 times the rate among Whites (up from 1.2 in 2019), 1.5 times the rate among Hispanics (down from 1.8 in 2019), and 2.5 times the rate among Asians (down from 2.7 in 2019). The age-adjusted death rate among males was 1.5 times the rate among females in 2020. The rate rose 29.2% among males and 23.5% among females between 2019 and 2020. Rates varied across New Jersey counties from a low of 592.8 in Hunterdon County to a high of 1,105.6 in Cumberland County.
