Cities with Allergies
Each year, the Asthma and Allergy Foundation of America (AAFA) conducts Allergy Capitals, a research
project to determine the 100 most challenging places to live in for those who have allergies in the
spring and fall season. The results are based on 3 factors for 100 cities:
(1) pollen scores of airborne grass, tree, and weed pollen, as well as mold spores
(2) number of allergy medications used per patient
(3) number of allergy specialists per patient.
The data is recorded, measured, and compared versus the results from the previous
year, and the cities are ranked accordingly.
