How this ranking works

Rankings use HomeRiskIQ weather risk data across79/79 eligible cities evaluated.

Scores are normalized to a 0-100 scale. The state benchmark is a p85-based state reference, not an arithmetic average.

City entries link to hazard-specific pages where available, otherwise to the city overview.
