Adults with current asthma.
Estimated share of adults who currently have asthma. This is CDC PLACES’ modeled county estimate, built from BRFSS, Census population estimates, and ACS data—not a count of local diagnoses, an air-quality measurement, a measure of asthma severity, or a prediction of an individual’s risk. It describes the current adult population and can reflect care access, smoking, housing, work, age, and many other factors besides local conditions.
New Jersey has the lowest published asthma in this comparison, at 8.9%. The next states shown are Nebraska (9.0%) and California (9.3%).
The table orders 49 states by adults with current asthma. It describes one published measure, not an overall judgment about where to live.
Use the result as a starting point, then compare the underlying source, dates, and local county figures before making a decision. Estimated share of adults who currently have asthma.

Not ranked, because this measure is not published for them: Kentucky, Pennsylvania. CDC’s current 2025 PLACES release has no 2023-BRFSS modeled output for Kentucky or Pennsylvania. Unavailable is not zero asthma and should not be read as a finding about either state.
Free to use. The chart names its source and links back, so it stays honest wherever it ends up.
