Humid extreme heat
197.1 days/year
in the top 0.6% nationally
Lower is healthier
ST78thUS99thDefinition & 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 ›Floodplain exposure
44.6%
in the top 5.1% nationally
Lower is healthier
ST70thUS95thDefinition & 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.
Full methodology ›Obesity
26.1%
in the bottom 7.4% nationally
Lower is healthier
ST9thUS7thDefinition & source ›
The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.
Full methodology ›Physician access

in the top 9.6% nationally
Higher is healthier
ST74thUS90thDefinition & source ›
The number of physicians’ 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 ›Crowded housing

in the top 10.0% nationally
Lower is healthier

The share of occupied homes with more than one person per room, the Census definition of crowded housing.

The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.

The read
ZIP 33428, one of several in Boca Raton, Florida, by its overall standing, sits in the top 26% healthiest ZIPs nationally (8,439th) and the top 35% of Florida (342nd).
The measures fall on both sides of the ledger for this area: modeled obesity settles in the bottom 7.4% nationally. Distance to an emergency room registers at the national minimum, shared with about 11% of ZIPs. Physicians stands in the top 9.6% nationally, and grocery lands in the top 10.1% nationally. Distance to a community health center is at the national minimum, shared with about 23% of ZIPs. Set against that, modeled humid heat resides in the top 0.6% nationally, and floodplain exposure rests in the top 5.1% nationally. Crowded housing lies in the top 10.0% nationally, and housing-cost burden sits in the top 10.5% nationally. PFOA in drinking water settles in the top 11.2% nationally.
Held up against its neighbors, park land runs far lower than the surrounding ZIPs on this measure. Defined in plain terms, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". The nearest ZIP ranking healthier overall is ZIP 33067, 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 0.60 years of 81.9, 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.
