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.
Humid extreme heat
183.3 days/year
in the top 1.5% nationally
Lower is healthier
ST50thUS99thDefinition & 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
47%
in the top 4.5% nationally
Lower is healthier
ST73rdUS96thDefinition & 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 ›PFAS in drinking water
58.2%
in the top 8.7% nationally
Lower is healthier
ST65thUS91stDefinition & 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 ›Median household income
$123,899
in the top 8.5% nationally
Higher is healthier
ST94thUS92ndDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Stroke
2.5%
in the bottom 6.7% nationally
Lower is healthier
ST6thUS7thDefinition & source ›
The estimated share of adults who have been told by a health professional that they have had a stroke.
Full methodology ›Energy-cost burden
1.7%
in the bottom 7.2% nationally
Lower is healthier
ST19thUS7thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Hearing disability
5.3%
in the bottom 9.0% nationally
Lower is healthier
ST8thUS9thDefinition & source ›
The estimated share of adults who are deaf or have serious difficulty hearing.
Full methodology ›Coronary heart disease

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

The estimated share of adults who have difficulty doing errands alone, such as visiting a doctor’s office, because of a physical, mental, or emotional condition.

The read
Judged by its overall standing, ZIP 34638, one of several in Land O Lakes, Florida sits in the top 16% healthiest ZIPs nationally (5,114th) and the top 20% of Florida (196th).
An even profile, with readings pulling both ways: household income lands in the top 8.5% nationally, modeled stroke rests in the bottom 6.7% nationally, and modeled energy burden settles in the bottom 7.2% nationally. Modeled hearing disability lands in the bottom 9.0% nationally, park land rests in the top 10.5% nationally, and modeled coronary heart disease settles in the bottom 8.7% nationally. Distance to a community health center lands at the national minimum, shared with about 23% of ZIPs. Against that, modeled humid heat rests in the top 1.5% nationally, and floodplain exposure settles in the top 4.5% nationally. Modeled pfas lands in the top 8.7% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure. Put plainly, 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. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". A healthier nearby ZIP overall is ZIP 33556, 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

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.
