ZIP 61101, one of several in Rockford, Illinois, by its composite score, sits in the bottom 4.8% nationally (30,535th) and the bottom 1.2% of Illinois (1,352nd).
The data opens on real and measurable burdens: modeled self-care disability rests in the top 3.3% nationally, and obesity resides in the top 0.9% nationally. Modeled independent living disability is in the top 3.3% nationally, and vision disability lands in the top 4.1% nationally. Modeled fair or poor health stands in the top 5.0% nationally, utility shutoff registers in the top 3.4% nationally, and housing insecurity settles in the top 3.7% nationally. Modeled food insecurity sits in the top 3.8% nationally, and transportation lies in the top 3.9% nationally. More encouragingly, lithium in drinking water rests in the bottom 2.4% nationally.
Next to the surrounding area, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 0.63 years of 73.7, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match. How distance is measured
