What defines this ZIP

Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.

Elder-services access

2.2 per 1,000 residents

in the top 0.08% nationally

Higher is healthier

ST99th
US99th
Definition & source ›

The number of services for older adults and people with disabilities inside this ZIP’s boundary, per 1,000 residents.

Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.

Walkability

0.63 intersections/sq mi

in the bottom 1.4% nationally

Higher is healthier

ST13th

Definition & source ›

The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

A balanced set of signals defines this area, not any single one: elder services is in the top 0.08% nationally, and modeled air-toxics cancer risk registers in the bottom 2.8% nationally. Distance to a hazardous-chemical facility lies in the top 2.9% nationally, and fiber broadband is in the top 5.1% nationally. Distance to a Superfund site registers in the top 6.3% nationally, and modeled short sleep lies in the bottom 6.2% nationally. By contrast, walkability is in the bottom 1.4% nationally, distance to a nursing home registers in the top 2.1% nationally, and distance to an emergency room lies in the top 3.1% nationally. Modeled radon is in the top 8.9% nationally.

Set beside the wider area around it, distance to a hazardous-chemical facility runs far higher than the surrounding ZIPs on this measure. For clarity, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. 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. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. ZIP 57640, just across the boundary, ranks better overall among the ZIPs nearby.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 1.54 years of 78.2, 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.
