AAFA’s 2024 Asthma Capitals™ report underscores the crucial impact of indoor air quality on asthma management and health disparities across U.S. cities
At Allergy Standards Ltd, we are proud partners with the Asthma and Allergy Foundation of America (AAFA) in delivering the Asthma & Allergy Friendly® Certification Program. AAFA’s 2024 Asthma Capitals™ report has just been released, shedding light on how geographic factors influence asthma outcomes across the United States. The report ranks the 100 largest U.S. cities based on asthma-related challenges, offering crucial insights into the environmental and socioeconomic factors that impact the nearly 28 million Americans living with asthma.

Key Health Outcomes and Disparities in Asthma Management
The 2024 Asthma Capitals™ report assesses cities based on three primary health outcomes:
- Asthma Prevalence: The number of people diagnosed with asthma in each city.
- Emergency Department Visits: Rates of ER visits due to asthma exacerbations.
- Asthma-Related Deaths: Mortality rates attributed to asthma.
In addition to these outcomes, the report emphasizes how external factors like poverty, access to medical care, and air quality contribute to disparities in asthma management. Allentown, Pennsylvania, ranks as the most challenging city for asthma for the second consecutive year, highlighting the urgent need for intervention in high-burden communities.
The Role of Indoor Air Quality (IAQ) in Asthma Management
AAFA’s report reinforces the importance of Indoor Air Quality (IAQ) as a critical factor in managing asthma. As most people spend up to 90% of their time indoors, the air quality inside homes, workplaces, and schools has a significant effect on asthma outcomes. Indoor air can be up to five times more polluted than outdoor air, containing asthma triggers such as:
- Dust mite allergen
- Pet dander
- Mold spores
- Pollen
- Volatile Organic Compounds (VOCs)
These triggers can exacerbate asthma symptoms, particularly in poorly ventilated spaces or environments with high humidity. In homes and buildings, these pollutants often accumulate due to cleaning products, building materials, and inadequate ventilation.
At Allergy Standards, we recognize the importance of addressing IAQ for people impacted by asthma and allergies. Our Asthma & Allergy Friendly® Certification Program tests and certifies products such as air purifiers, building materials, and bedding to meet stringent standards for reducing allergens and irritants. By using Certified products, families can significantly improve their indoor environment, reducing exposure to harmful pollutants and allergens.
Spotlight on Allentown, PA: Addressing Asthma Disparities
Allentown, Pennsylvania, has been ranked the #1 Asthma Capital in 2024, underscoring the challenges faced by many urban areas in managing asthma. Factors such as poor air quality, poverty, and limited access to healthcare exacerbate asthma symptoms and make the condition more difficult to manage. In response, AAFA’s Health Equity Advancement and Leadership (HEAL) Program is addressing these disparities by funding community-based asthma management programs in high-burden areas like Allentown.
HEAL initiatives focus on creating new care pathways and providing education, resources, and access to better asthma management tools for underserved communities. These efforts are a critical part of AAFA’s broader mission to reduce the burden of asthma across the country and to provide equitable access to the care and resources necessary for managing the condition.
Advocacy for Better Asthma Outcomes
AAFA’s 2024 Asthma Capitals™ report is not only an analysis of asthma outcomes but also a call to action. It emphasizes the need for advocacy at both the local and national levels to improve asthma care and reduce health disparities. AAFA promotes a “health in all policies” approach, recognizing that policy decisions in areas such as housing, education, and the environment can have a profound impact on asthma outcomes.
Advocacy efforts can drive policy changes that improve IAQ standards, increase access to healthcare, and provide funding for asthma education programs. AAFA offers resources to help individuals and organizations get involved in advocacy, from contacting legislators to raising awareness during peak asthma times, such as Asthma Peak Month in September.
