Where each domain sits inside this metro
The Score above is one number for the whole Norwich-New London, CT metro. Nine domains make it up, and they are not spread the same way across the people who live here. Each row divides this metro's ZIP codes into fifths by how they stand against each other on that domain, then counts who lives at each end. If a domain were spread evenly across the metro's residents, every row would read about 20%.
The highest-standing fifth
6 of 29 ZIPsShare of the metro's residents living in the fifth of its ZIP codes that stand highest on each domain.

Each fifth is about 6 of this metro’s 29 compared ZIP codes, and the shares are out of 269,455 residents. A ZIP code is compared here only if it carries a resident count to weight it by and enough measured data on that domain — the rest are left out of that domain’s fifths rather than filled in from a coarser geography, which is why this count can sit just below the metro’s scored total.
The mark shows 20% — where a row would sit if that domain were spread evenly across the metro's residents.
Each ZIP code is compared with the other ZIP codes in this metro that are measured across all nine scoring domains — not with all US ZIP codes. Percentages are rounded; higher is healthier in every domain.
Why this matters
The ZipVitals Score combines nine domains of health — from chronic disease and preventive care to environmental hazard, social need, and healthcare access — into one 0–100 index for each ZIP code, computed the same way everywhere from public federal and academic data. The Norwich-New London, CT figures on this page are population-weighted rollups of those per-ZIP scores, so they describe the metro's residents rather than a coarser geography relabeled as the metro.
A high score describes favorable documented conditions; it is not a claim about individual residents, and it does not capture everything that shapes a community's health. Where a ZIP code scores low, that pattern reflects structural conditions — investment, environment, and access — far more than the choices of the people who live there.
