Physician access

Higher is healthier
ST82ndUS94thDefinition & 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.

The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

ST4thUS2ndDefinition & 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 ›The read
By the composite health measure, ZIP 33770, one of several in Largo, Florida ranks in the bottom 44% nationally (18,062nd) and the bottom 36% of Florida (627th).
The picture here is genuinely mixed, with readings on both sides: distance to an emergency room rests at the national minimum, shared with about 11% of ZIPs. Physicians stands in the top 5.8% nationally, and walkability lies in the top 6.7% nationally. Outpatient lands in the top 7.5% nationally. Modeled extreme heat sits at the national minimum, shared with about 19% of ZIPs. Modeled radon is in the bottom 1.9% nationally, grocery settles in the top 10.8% nationally, and recreation resides in the top 11.0% nationally. On the other side, housing-cost burden registers in the top 7.9% nationally, and households without a vehicle rests in the top 8.6% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Close by, ZIP 33756, just across the boundary, ranks healthier overall.

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 0.53 years of 76.5, 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.
