How this ranking works

Ranks are each ZIP code’s position in the full national ZipVitals Score ranking, so the numbers jump — this metro holds 17 of the tens of thousands of scored US ZIP codes — and they never change with the sort direction; the rank a ZIP carries here is the rank it carries everywhere on this site. A ZIP whose data is too thin to score is held out entirely rather than filled from county or metro figures.

A high score describes favorable documented conditions — never a claim about residents. Where ZIP codes score low, that pattern reflects structural conditions — investment, environment, and access — far more than the choices of the people who live there.
