Full methodology ›The read
On the composite measure, Armstrong, Illinois (ZIP 61812) stands in the bottom 44% nationally (17,993rd) and the bottom 37% of Illinois (861st).
A balanced set of signals defines this area, not any single one: modeled pfas lands in the bottom 3.5% nationally, and housing-cost burden settles in the bottom 4.6% nationally. Households without a vehicle rests at the national minimum, shared with about 16% of ZIPs. Poverty lands in the bottom 12.8% nationally. Crowded housing settles at the national minimum, shared with about 29% of ZIPs. Modeled disaster risk rests in the bottom 15% nationally, and unemployment lands in the bottom 16% nationally. By contrast, modeled mammography settles in the bottom 9.4% nationally, obesity rests in the top 10.5% nationally, and radon lands in the top 16% nationally.
For clarity, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. ZIP 61831, just across the boundary, ranks better overall among the ZIPs nearby.

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 0.99 years of 77.7, 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.
