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
Barriers to reaching care
- Distance to the nearest emergency room
- Distance to the nearest community health center
- Households with no vehicle
- Limited home internet for telehealth

Baker, California (ZIP 92309), overall, ranks in the bottom 9.6% nationally (29,009th) and the bottom 7.1% of California (1,597th).
The profile reads plainly, and several measures carry it: modeled colon screening lies in the bottom 1.2% nationally, distance to a nursing home stands in the top 1.1% nationally, and modeled extreme heat rests in the top 1.3% nationally. Distance to an emergency room registers in the top 1.4% nationally, walkability resides in the bottom 1.4% nationally, and modeled fair or poor health settles in the top 3.6% nationally. Modeled vision disability is in the top 4.7% nationally, and uninsured sits in the top 4.6% nationally. Homeownership lands in the bottom 2.8% nationally, and distance to a community health center lies in the top 3.0% nationally.
Defined simply, extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. ZIP 89019, about 5.7 miles away, comes out healthier overall. This area also 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 1.77 years of 74.1, 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.
