How Metro Scores Are Calculated
Each ZIP code receives a Home Safety Score (0-100) based on four equally weighted factors:
- Water Quality — EPA violation history and compliance status
- Lead & Copper — 90th percentile lead levels vs. EPA action level
- Radon Risk — EPA radon zone classification
- Flood Risk — FEMA flood insurance claims and zone data
The metro score is the average of all ZIP codes in the area.
