What the distribution shows
Across Illinois’s 1,381 ZIP codes, the ZipVitals Score spans a wide range. 1,368 of them carry enough measured coverage across all nine health domains to enter the population-weighted composite above; the rest are held out rather than filled from a coarser geography.
Assembled from the same ZIP-level data as every per-ZIP page. Read the full method →
Where Illinois stands, domain by domain
The ZipVitals Score above combines nine domains of health into one number. This is where Illinois's ZIP codes sit against ZIP codes across the country on each of them, weighted by how many residents live in each one — strongest at the top.
Healthcare Access · 76th
Weighted by residents, this state’s ZIP codes sit around the 76th percentile of US ZIP codes here — its highest of the nine scoring domains.
Environmental Hazard · 20th
Weighted by residents, this state’s ZIP codes sit around the 20th percentile of US ZIP codes here — its lowest of the nine scoring domains.
Read each bar as a national percentile from 0 to 100. The dark line marks the national median: a bar past it means Illinois's ZIP codes typically place above most ZIP codes in the country on that domain. A domain Illinois cannot place honestly is shown greyed as "Not enough data" rather than given a number.
Each figure is the population-weighted average of this state's ZIP codes' standing on that domain, compared with the ZIP codes measured across all nine scoring domains — not with all US ZIP codes. A ZIP code counts toward a domain only if it carries enough measured data on it and enough of Illinois's residents live in the ZIP codes that do; the rest are held out rather than filled in from a coarser geography.

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 Illinois figures on this page are population-weighted rollups of those per-ZIP scores, so they describe Illinois's residents rather than a coarser geography relabeled as the state.
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.
