Humid extreme heat

Lower is healthier
ST59thUS99thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.

ST25thUS5thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›High cholesterol

The estimated share of adults with high cholesterol, among those who have ever been screened for it.

The estimated share of adults who have been told by a health professional that they have coronary heart disease or angina.
Full methodology ›Elder-services access

Higher is healthier
ST91stUS88thDefinition & 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.

The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.

Full methodology ›The read
Judged by its overall standing, ZIP 34433, one of several in Dunnellon, Florida sits in the bottom 47% nationally (16,925th) and the bottom 39% of Florida (598th).
A few readings account for most of this area's strain: modeled humid heat settles in the top 1.2% nationally, high cholesterol lands in the top 4.6% nationally, and coronary heart disease rests in the top 9.0% nationally. Modeled pfas settles in the top 12.8% nationally, modeled hearing disability lands in the top 15% nationally, and distance to an emergency room rests in the top 18% nationally. On the better side, modeled arsenic settles in the bottom 4.6% nationally, and elder services lands in the top 11.7% nationally. Distance to a Superfund site rests in the top 16% nationally, and modeled binge drinking settles in the bottom 17% nationally.
Placed beside its immediate neighbors, park land runs far lower than the surrounding ZIPs on this measure. Put plainly, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. A healthier nearby ZIP overall is ZIP 34461, about 2.2 miles away.

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 0.73 years of 77.6, 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.
