Categories shown for non-Hispanic adults are for those who selected only one racial group. Adults categorized as Hispanic may be of any race or combination of races. Data are based on a yes response to the survey question, “Have you ever been told by a doctor or other health professional that you had chronic obstructive pulmonary disease, COPD, emphysema, or chronic bronchitis? ” Estimates are age adjusted using the projected 2000 U.S. population as the standard population and four age groups: 18–44, 45–64, 65–74, and 75 and older.
