Chronic Obstructive Pulmonary Disease (COPD) Prevalence by Year, New Jersey, 2011 to 2021

Indicator Report Data View Options

  • NAData not available

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.


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.

Data Notes

Data Source

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

How the Measure is Calculated

  • 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.

Data Issues

Data from the New Jersey Behavioral Risk Factor Survey are intended to be representative of all non-institutionalized adult residents of New Jersey. Due to resource issues, however, adults with limited personal access to phone service or limited command of either English or Spanish are not represented. As with all surveys, also, some error results from nonresponse (e.g., refusal to participate in the survey or to answer specific questions), and faulty measurement (e.g., responses affected by social desirability or recall error). Data collection procedures intended to minimize such errors include the use of strict calling protocols, good questionnaire design, standardization of interviewer behavior, interviewer training, and frequent, on-site interviewer monitoring and supervision. Statistical weighting procedures are also used to minimize the potential impact of disproportionate representation of demographic subgroups defined in terms of age, sex, race, ethnicity, education level, marital status, home ownership, and county of residence.
