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
- Food insecurity
- Housing insecurity
- Adults reporting fair or poor health
- Chronic conditions
Barriers to reaching care
- Thin local supply of doctors
- Thin local supply of pharmacies
- Limited home internet for telehealth

On balance, and by the composite measure, Sultana, California (ZIP 93666) ranks in the bottom 3.2% nationally (31,057th) and the bottom 1.6% of California (1,693rd).
Plainly stated, a few measures mark out this area: modeled vision disability rests in the top 0.4% nationally, and colon screening is in the bottom 0.4% nationally. Modeled fair or poor health stands in the top 0.2% nationally, and uninsured settles in the top 1.4% nationally. Modeled self-care disability lies in the top 0.9% nationally, nitrate resides at the national maximum, and fine-particle lands in the top 0.2% nationally. Modeled housing insecurity registers in the top 0.4% nationally, crowded housing sits in the top 0.5% nationally, and modeled cognitive disability rests in the top 1.5% nationally.
Compared with the ZIPs it borders, crowded housing runs far higher than the surrounding ZIPs on this measure. In plainer terms, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. For a healthier nearby ZIP overall, look to ZIP 93618, 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 1.43 years of 82.0, 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. How distance is measured
