Higher is healthier
ST96thUS94thDefinition & source ›
The number of public-transit stops 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 ›Grocery access
0.19 per 1,000 residents
in the top 7.8% nationally
Higher is healthier
ST94thUS92ndDefinition & source ›
The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”
Full methodology ›Homeownership rate
48.2%
in the bottom 8.1% nationally
Higher is healthier
ST11thUS8thDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.

Lower is healthier
ST15thUS2ndDefinition & 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 ›Park land

The share of this ZIP’s land area that is public parkland.
Full methodology ›The read
ZIP 78218, one of several in San Antonio, Texas, in overall standing, comes out in the bottom 26% nationally (23,685th) and the bottom 40% of Texas (1,121st).
The profile carries real weight, and several readings make that plain: modeled uninsured resides in the top 2.3% nationally, extreme heat sits in the top 2.1% nationally, and short sleep stands in the top 4.9% nationally. Modeled humid heat resides in the top 4.4% nationally, homeownership sits in the bottom 8.1% nationally, and modeled vision disability stands in the top 10.1% nationally. Better still, subsidized affordable housing resides in the top 1.2% nationally, and transit sits in the top 6.1% nationally. Grocery stands in the top 7.8% nationally, and modeled radon resides in the bottom 2.0% nationally.
Set within its surrounding area, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. The closest healthier ZIP overall is ZIP 78209, 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 0.68 years of 75.3, 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
