Score

Overall Allergy Score

Composite allergy-friendliness score from pollen, mold, dust mite, and wildfire-smoke exposure scores.

Scale0-100

Higher values rank better for this score.

How It's Calculated

The latest published score is normalized to a 0-100 scale. The method below explains what the score rewards, with technical source metadata available for audit.

Scoring Method

How the ranking is built

Overall Allergy Score combines pollen, mold, dust mite, and wildfire-smoke exposure scores into one allergy-friendliness score.

  1. 1

    The composite is 55% Low Pollen Burden, 22% Low Mold Allergy Risk, 15% Low Dust Mite Allergy Risk, and 8% Low Wildfire Smoke Risk.

  2. 2

    It is a weighted average of already-published 0-100 component scores.

Known Limits

  • This is an environmental allergy-friendliness proxy, not medical advice or a personal symptom forecast.
  • It does not include observed pollen counts, personal sensitization, indoor building conditions, medication access, or clinical outcomes.
  • The smoke component is included as a respiratory irritant proxy, not a true allergen.
