Health need and barriers to care documented here
On our reading, this ZIP code carries the overlap at its severe level: severe means at least four of the six health-need readings and at least four 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
- Distance to the nearest emergency room
- Thin local supply of doctors
- Thin local supply of pharmacies
- Households with no vehicle
- Limited home internet for telehealth

Niland, California (ZIP 92257), by its composite score, sits in the bottom 1.4% nationally (31,644th) and the bottom 0.3% of California (1,715th).
A few measures stand out on the ground and lead the picture: modeled self-care disability is in the top 0.7% nationally, and vision disability lands in the top 1.2% nationally. Modeled extreme heat stands in the top 0.03% nationally, and fair or poor health registers in the top 0.5% nationally. Modeled mobility disability settles in the top 0.5% nationally, tooth loss sits in the top 1.3% nationally, and arsenic lies in the top 0.2% nationally. Modeled stroke rests in the top 1.1% nationally, independent living disability resides in the top 1.7% nationally, and coronary heart disease is in the top 0.9% nationally.
Next to the surrounding area, arsenic runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. For a healthier comparison close by, see ZIP 92227, just across the boundary. The area further 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.

Clean environment, heavy chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 91.2 (top 10%); chronic-disease standing 2.4 (bottom 10%) — 89 points apart, cleaner on the environment than it is on chronic illness.
Ranked #155 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

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

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
