The number of dental 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 78230, one of several in San Antonio, Texas, overall, ranks in the top 19% healthiest ZIPs nationally (6,081st) and the top 9.7% of Texas (181st).
This area's measures are easy to read as a mixed set: dental providers is in the top 5.0% nationally, physicians sits in the top 7.4% nationally, and outpatient lands in the top 7.9% nationally. Transit lies in the top 8.4% nationally. Set against that, modeled extreme heat stands in the top 2.5% nationally, and loud transportation noise rests in the top 3.7% nationally. PFAS in drinking water registers at the national maximum, and modeled humid heat resides in the top 5.7% nationally. Homeownership settles in the bottom 8.5% nationally, and modeled disaster risk is in the top 8.6% nationally.
Measured against the nearby ZIPs, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. ZIP 78231, just across the boundary, comes out 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 0.85 years of 81.0, 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.
