Physician access

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 ›The read
ZIP 94304, one of several in Palo Alto, California, on the composite measure, lands in the top 0.2% healthiest ZIPs nationally (44th) and the top 0.6% of California (10th).
The profile cuts both ways, and the readings bear that out: physicians registers in the top 0.08% nationally, modeled obesity lands in the bottom 0.7% nationally, and civic resides in the top 0.4% nationally. Modeled utility shutoff lies in the bottom 0.5% nationally, dental providers settles in the top 0.7% nationally, and outpatient stands in the top 0.8% nationally. Transit is in the top 1.0% nationally, and household income rests in the top 3.4% nationally. Working the other way, outer-floodplain exposure sits in the top 0.5% nationally, and slow internet speeds registers in the top 0.8% nationally.
Set against the neighboring ZIPs, physicians runs far higher than the surrounding ZIPs on this measure. In everyday language, outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". A healthier neighbor overall sits at ZIP 94022, 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 0.75 years of 83.2, 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. How distance is measured
