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.
Arsenic in groundwater
0.87%
in the bottom 0.7% nationally
Lower is healthier
ST3rdUS1stDefinition & 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 ›Fatal road crashes
88.6 per 100,000 residents per year
in the top 0.7% nationally
Lower is healthier
ST99thUS99thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Humid extreme heat
190.2 days/year
in the top 1.0% nationally
Lower is healthier
ST67thUS99thDefinition & 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.
Full methodology ›Grocery access
0.17 per 1,000 residents
in the top 9.4% nationally
Higher is healthier
ST88thUS91stDefinition & source ›
The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”
Full methodology ›Uninsured (under 65)
16.2%
in the top 8.8% nationally
Lower is healthier
ST68thUS91stDefinition & source ›
The estimated share of adults aged 18–64 with no current health-insurance coverage.

Higher is healthier
ST93rdUS87thDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.
Full methodology ›Slow internet speeds

Full methodology ›The read
Overall, Port St. Lucie, Florida (ZIP 34945) lands in the bottom 45% nationally (17,729th) and the bottom 36% of Florida (620th).
Several measures weigh most on this area's profile, and they come first: fatal road crashes stands in the top 0.7% nationally, and modeled humid heat lies in the top 1.0% nationally. Modeled uninsured lands in the top 8.8% nationally, and slow internet speeds sits in the top 13.3% nationally. Modeled loud transportation noise is in the top 17% nationally, PFOA in drinking water settles in the top 18% nationally, and modeled pfas resides in the top 18% nationally. On the better side, modeled arsenic registers in the bottom 0.7% nationally, grocery rests in the top 9.4% nationally, and homeownership stands in the top 13.1% nationally.
Set beside the nearby areas, park land runs far lower than the surrounding ZIPs on this measure. A note on the terms: arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. 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. For a healthier nearby comparison, ZIP 32968, just across the boundary, ranks better overall.

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 82.4, 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
