QuickStats: Age-Adjusted Death Rates from Chronic Obstructive Pulmonary Disease (COPD)* Among Persons Aged ≥55 Years, by Sex and Urbanization of County of Residence†— United States, 2009–2011
* Per 100,000 standard population. Deaths from COPD are those coded J40–J44 in the International Classification of Diseases, 10th Revision.
† Counties were classified into urbanization levels based on a classification scheme that considers metropolitan/nonmetropolitan status, population, and other factors.
§ 95% confidence interval.
During 2009–2011, higher death rates for COPD among persons aged ≥55 years were associated with more rural localities, with rates increasing steadily from the least to the most rural county. For males, the age-adjusted COPD death rate in rural counties was 59% higher than in large central metropolitan counties (284.3 versus 178.9 deaths per 100,000 population). For females, the age-adjusted COPD death rate in rural counties was 39% higher than in large central metropolitan counties (193.6 versus 139.3 deaths per 100,000 population). COPD death rates for males were 21% to 47% higher than for females, with the largest differentials observed in nonmetropolitan counties (i.e., town/city and rural counties).
