Health need and barriers to care documented here
On our reading, this ZIP code carries the overlap at its acute level: acute means at least three of the six health-need readings and at least three of the six access barriers apply to the same place.
These are two separate readings of public data that both apply to this place — never a claim that one causes the other, never a severity score, and never a statement about any person who lives here.
Health need documented here
- People without health insurance
- People living in poverty
- Housing insecurity
Barriers to reaching care
- Distance to the nearest emergency room
- Thin local supply of doctors
- Thin local supply of pharmacies
- Limited home internet for telehealth
A reading appears below only where this ZIP code is among the most-affected 10% of US ZIP codes on it — one national bar, the same for every ZIP in the country.

On balance, and by the composite measure, Potrero, California (ZIP 91963) ranks in the top 49% healthiest ZIPs nationally (15,635th) and the bottom 40% of California (1,038th).
Plainly stated, a few measures mark out this area: crowded housing sits in the top 0.2% nationally, and poverty rests in the top 0.4% nationally. Housing-cost burden is in the top 1.8% nationally, and homeownership stands in the bottom 3.3% nationally. Distance to a nursing home settles in the top 3.9% nationally, distance to an emergency room lies in the top 5.5% nationally, and modeled disaster risk resides in the top 5.5% nationally. Better still, transit lands in the top 1.8% nationally, park land registers in the top 4.5% nationally, and civic sits in the top 5.0% nationally.
Compared with the ZIPs it borders, crowded housing runs far higher than the surrounding ZIPs on this measure. In plainer terms, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. For a healthier nearby ZIP overall, look to ZIP 91917, just across the boundary. The area additionally shows documented health need overlapping with barriers to reaching care, sitting in the most-affected 10% of US ZIP codes on several need measures and several access barriers.

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 1.32 years of 79.9, 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.
