Full methodology ›The read
By the composite health measure, Porter Ranch, California (ZIP 91326) ranks in the top 3.3% healthiest ZIPs nationally (1,044th) and the top 9.1% of California (155th).
The picture here is genuinely mixed, with readings on both sides: modeled obesity stands in the bottom 1.0% nationally, and household income lies in the top 4.1% nationally. Modeled utility shutoff lands in the bottom 2.8% nationally, and tooth loss sits in the bottom 1.8% nationally. Modeled cognitive disability is in the bottom 6.8% nationally, and home broadband subscription settles in the top 9.4% nationally. On the other side, modeled disaster risk resides in the top 3.8% nationally, modeled expected annual loss registers in the top 5.9% nationally, and housing-cost burden rests in the top 6.6% nationally. Lithium in drinking water stands in the top 9.7% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Close by, ZIP 91302, about 7.7 miles away, ranks healthier overall.

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 0.69 years of 84.2, 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
