A Comprehensive List of Asthma Facts and Statistics

Asthma Facts and Statistics GraphAs you may know, asthma is a chronic inflammation of the lung airways that causes coughing, chest tightness, wheezing or shortness of breath.

Some people have a severe case of asthma that limits their lifestyle and mobility, while others have acute problems that flare up at unexpected moments.

In the United States alone, more than 24 million adults and children suffer from asthma, and it’s one of the leading causes for missing work and school.

Interestingly, there’s a big difference between how men and women are affected by asthma, as well as various ethnic groups.

Sadly, this disease is also responsible for about 10 deaths every single day.

Below is a comprehensive list of the top asthma facts and statistics. You’ll find data on how many people suffer from this disease, who is most at risk and the costs associated with asthma conditions.

Note: Many people confuse asthma and bronchitis with each other. To find out how they differ visit our page on Asthma vs Bronchitis: How to Spot the Differences.
