Estimated Prevalence and Incidence of Lung Disease

Estimated Prevalence and Incidence of Lung Disease provides prevalence estimates of asthma and COPD (chronic obstructive pulmonary disease) as well as the incidence of lung cancer at the county and state levels. Data are based on the 2014 Behavioral Risk Factor Surveillance Survey and the 2015 joint report from CDC's National Program of Cancer Registries, NCI's SEER program, and state-based cancer registries.

Please note that these numbers reflect the estimated prevalence and incidence of lung disease within each county and state, and not the actual number. That is, the estimate is derived from national and/or state data and adjusted for the age-specific population of each area. Many other factors may affect actual prevalence. When citing these data, make efforts to ensure that the limitations of the estimates are understood. See the full methodology for additional information.

Do not combine individual disease counts to obtain a total lung disease estimate as this double counts those diagnosed with more than one lung disease.
