Where these ZIPs differ, domain by domain

Nine domains make up the ZipVitals Score. Each one is placed on the same national scale, and the domains where these ZIPs are furthest apart come first. Higher is healthier in every one.

Compared with the ZIP codes measured across all nine scoring domains — not with all US ZIP codes. How the score works, and who it compares you with ›

Every ranking, bar and gap below is measured against the same national group. Where a ZIP’s line also mentions its state or its metro area, that figure is measured against a different group — its own — so it is context for that one ZIP and never a comparison between them.

“Of the score” is the domain’s weight in the ZipVitals Score — a property of the score itself, the same on every ZIP. A gap is the distance between the highest and lowest of these ZIPs on that domain’s national scale. Percentages are rounded; higher is healthier in every domain.

Data release 2026 · higher is healthier on every row. How the ZipVitals Score is calculated →

The State rank and Metro rank rows show no “Leads” marker: each ZIP is ranked against the ZIPs in its own state and the ZIPs in its own metro area, so those ranks are not ordered against one another.
