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 living in poverty
- Food insecurity
- Housing insecurity
Barriers to reaching care
- 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, ZIP 91330, one of several in Northridge, California ranks in the top 23% healthiest ZIPs nationally (7,440th) and the top 40% of California (680th).
Plainly stated, a few measures mark out this area: modeled loneliness registers in the top 0.01% nationally, and poverty sits at the national maximum. Homeownership rests at the national minimum, and slow internet speeds is in the top 0.6% nationally. Modeled pfas stands in the top 0.8% nationally, and cognitive disability settles in the top 2.0% nationally. Better still, modeled obesity lies in the bottom 1.1% nationally, housing-cost burden resides at the national minimum, and fatal road crashes lands at the national minimum. Home broadband subscription registers at the national maximum.
Compared with the ZIPs it borders, poverty runs far higher than the surrounding ZIPs on this measure. In plainer terms, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. For a healthier nearby ZIP overall, look to ZIP 91326, less than a tenth of a mile away. 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

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
