    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?

COPD is a serious lung disease that makes it hard to breathe and gets worse over time. COPD can cause coughing with or without large amounts of mucus, wheezing, shortness of breath, chest tightness, and other symptoms. When COPD is severe, it can cause serious, long-term disability.

How Are We Doing?

In 2020, the adult COPD age-adjusted prevalence in New Jersey was 4.5%. Blacks (4.9%) and Whites (4.6%) have a higher prevalence of COPD compared to Hispanics (3.9%), and Asians (2.5%) in the state.


*2019 data is not included in the average estimated prevalence. No data is available for 2019. All prevalence estimates are age-adjusted to the U.S. 2000 standard population.

Data Sources

Behavioral Risk Factor Survey, Center for Health Statistics, New Jersey Department of Health, []  

Measure Description for Chronic Obstructive Pulmonary Disease (COPD) Prevalence

Definition: Estimated percentage of New Jersey adults (ages 18 and over) who have been diagnosed with COPD. In the United States, the term "COPD" includes two main conditions: emphysema and chronic bronchitis. Because most people diagnosed with COPD have both emphysema and chronic bronchitis, the general term "COPD" is often used.
Numerator: Number of adults from the Behavioral Risk Factor Surveillance System who have been told by a doctor, nurse or other health professional that they have COPD, emphysema or chronic bronchitis.
Denominator: Number of survey respondents excluding those with missing, "Don't know/Not sure," and "Refused" responses.
