in the bottom 3.1% nationally
Lower is healthier
ST15thUS3rdDefinition & 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 ›Expected annual disaster loss
$0
in the bottom 6.3% nationally
Lower is healthier
ST2ndUS6thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.
Full methodology ›Floodplain exposure
0.95%
in the bottom 12.1% nationally
Lower is healthier
ST2ndUS12thDefinition & 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 ›Distance to a Superfund site
48.4 mi

ST3rdUS14thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Distance to a hazardous-chemical facility
9.3 mi
in the top 15% nationally
Higher is healthier
ST92ndUS85thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.
Full methodology ›The read
On the coverage assembled to date, for Holder, Florida (ZIP 34445), health standing is not ranked here — the available data is too limited to place it confidently.
The measures that are covered come first, caveats noted: poverty rests at the national minimum, and homeownership is at the national maximum. Home broadband subscription stands at the national maximum, and modeled arsenic settles in the bottom 3.1% nationally. Modeled expected annual loss lies in the bottom 6.3% nationally. Unemployment resides at the national minimum, shared with about 15% of ZIPs. Households without a vehicle lands at the national minimum, shared with about 16% of ZIPs. Modeled loud transportation noise registers at the national minimum, shared with about 22% of ZIPs. By contrast, modeled humid heat sits in the top 1.1% nationally. Fiber broadband rests at the national minimum, shared with about 19% of ZIPs.
Compared with the ZIPs it borders, park land runs far lower than the surrounding ZIPs on this measure. In plainer terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors.

| Life expectancy at birth | 76.1 yr ± 0.87 | 78.9 yr (74.7–82.8) n=31,308 | 78.2 yr (74.6–82.2) n=894 |
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 0.87 years of 76.1, and it’s very unlikely to be off by more than twice that.
