Asthma Capitals

The 2025 Asthma Capitals Report is embargoed until Sept. 9 2025, until 7 a.m. ET. If you have any questions, contact us at gro.afaa@aidem.

The Asthma and Allergy Foundation of America’s (AAFA) Asthma Capitals™ report ranks the largest 100 cities in the contiguous (“lower 48”) U.S. by how challenging they are to live in when you have asthma. AAFA publishes this report to show the nationwide burden of asthma. It is a call to action to help the over 28 million people in the U.S. with asthma.

Asthma is greatly influenced by where someone lives. People who have affordable and accessible health care, clean air, and economic stability have a greater chance of managing and controlling their asthma. The report ranks cities based on: asthma rates, emergency room visits, and deaths. These outcomes are influenced by various risk factors.

About the Report

AAFA publishes the Asthma Capitals™ report to raise awareness about the nationwide impacts of asthma. The report analyzes asthma data across the United States and ranks cities by the most critical of health outcomes – asthma prevalence, emergency department visits due to asthma attacks, and asthma-related mortality. The outcomes are not weighted equally. The report also examines asthma risk factors that influence the outcomes.

AAFA only evaluates the top 100 populated places (based on metropolitan statistical areas or MSAs) in the contiguous (“lower 48”) states for this report. MSAs are cities and their surrounding areas (like suburbs and nearby rural areas). The report does not reflect:

  • Cities and areas not in the top 100 list by population size
  • Completely rural areas that are not located within a metropolitan statistical area
  • Anchorage, Alaska and Honolulu, Hawaii due to lack of matching data with other cities, counties, states
