This data measures the percentage of Arizonans who reported being told by a healthcare professional that they have asthma.

A respiratory condition with varying intensity of symptoms, asthma has become more prevalent over time and includes symptoms such as difficulty breathing, wheezing, chest tightness, and coughing, among others. As a significant quality-of-life issue, untreated asthma can prevent people from working or engaging in outdoor activities and can increase the risk of other respiratory ailments.

Research has drawn a clear relationship between poor air quality, especially particulates, as a contributor to asthma symptoms. Some epidemiological studies have also drawn a relationship between ozone and asthma; however, the studies are inconsistent.

Asthma data are updated annually and are available for the following localities:

  • Nation
  • States
  • Counties
