By its overall health score, Flat Rock, Illinois (ZIP 62427) lands in the bottom 42% nationally (18,632nd) and the bottom 33% of Illinois (923rd).
Strengths and concerns sit side by side across the measures here: homeownership resides in the top 9.7% nationally, and modeled transportation noise lands in the bottom 11.9% nationally. Unemployment registers in the bottom 15% nationally. Outer-floodplain exposure sits at the national minimum, shared with about 36% of ZIPs. On the other hand, distance to a hazardous-chemical facility rests at the national minimum, shared with about 31% of ZIPs. Recreation is at the national minimum, shared with about 35% of ZIPs. Physicians stands at the national minimum, shared with about 38% of ZIPs. Childcare settles at the national minimum, shared with about 42% of ZIPs. Modeled mammography lies in the bottom 20% nationally, and crowded housing resides in the top 22% nationally.
To translate a couple of terms, distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Overall, the nearest healthier neighbor is ZIP 62454, just across the boundary.

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 1.44 years of 78.6, 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.
