Humid extreme heat

ST42ndUS98thDefinition & 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.

5.4%

Lower is healthier
ST89thUS93rdDefinition & 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 ›Walkability
110 intersections/sq mi
in the top 8.6% nationally
Higher is healthier
ST89thUS91stDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

ST91stUS91stDefinition & source ›
The share of this ZIP’s land area that is public parkland.
Full methodology ›Radon
0.8 pCi/L
in the bottom 5.9% nationally
Lower is healthier
ST18thUS6thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Floodplain exposure

in the bottom 20% nationally
Lower is healthier
ST4thUS20thDefinition & 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 ›The read
In its overall standing, ZIP 33778, one of several in Largo, Florida lands in the top 39% healthiest ZIPs nationally (12,625th) and the top 50% of Florida (487th).
Taken together, the data gives a genuinely mixed reading: walkability sits in the top 8.6% nationally, and park land lands in the top 8.7% nationally. Modeled extreme heat lies at the national minimum, shared with about 19% of ZIPs. Dental providers stands in the top 11.0% nationally. Distance to a community health center rests at the national minimum, shared with about 23% of ZIPs. Modeled radon registers in the bottom 5.9% nationally. Distance to a nursing home resides at the national minimum, shared with about 27% of ZIPs. On the other side, modeled humid heat settles in the top 1.8% nationally, outer-floodplain exposure is in the top 6.8% nationally, and modeled industrial-pollution burden sits in the top 13.6% nationally.
Against the wider neighborhood, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put simply, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. On the overall standing, ZIP 33772, just across the boundary, ranks healthier.

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 0.82 years of 74.8, 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.
