PFAS in drinking water
93.6%

Lower is healthier
ST97thUS99thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Humid extreme heat
208.7 days/year
in the top 0.3% nationally
Lower is healthier
ST92ndUS99thDefinition & 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 ›Outer-floodplain exposure
24.1%
in the top 1.7% nationally
Lower is healthier
ST97thUS98thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Dental provider access
1.6 per 1,000 residents
in the top 2.2% nationally
Higher is healthier
ST96thUS98thDefinition & source ›
The number of dental offices located 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.
Full methodology ›Floodplain exposure

in the top 2.4% nationally
Lower is healthier
ST85thUS98thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

The read
Southwest Ranches, Florida (ZIP 33331), in overall standing, comes out in the top 5.8% healthiest ZIPs nationally (1,855th) and the top 3.7% of Florida (36th).
A balanced showing across the data, with a few readings each side: dental providers settles in the top 2.2% nationally, household income lands in the top 4.8% nationally, and modeled obesity rests in the bottom 5.6% nationally. Physicians settles in the top 4.0% nationally, and pharmacy lands in the top 4.6% nationally. Distance to an emergency room rests at the national minimum, shared with about 11% of ZIPs. On the other hand, modeled pfas settles in the top 0.2% nationally, and humid heat lands in the top 0.3% nationally. Outer-floodplain exposure rests in the top 1.7% nationally, and floodplain exposure settles in the top 2.4% nationally.
Set within its surrounding area, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, 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. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". The closest healthier ZIP overall is ZIP 33326, 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 1.20 years of 85.6, 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. How distance is measured
