Sylmar, California (ZIP 91342), overall, ranks in the top 48% healthiest ZIPs nationally (15,422nd) and the bottom 40% of California (1,028th).
Taken together, the data gives a genuinely mixed reading: park land lies in the top 2.6% nationally, and subsidized affordable housing stands in the top 4.6% nationally. Distance to an emergency room rests at the national minimum, shared with about 11% of ZIPs. On the other side, modeled expected annual loss registers in the top 0.4% nationally, and colon screening resides in the bottom 2.6% nationally. Modeled disaster risk settles in the top 1.2% nationally, and loneliness is in the top 1.6% nationally. Modeled loud transportation noise sits in the top 2.0% nationally, and crowded housing lands in the top 2.7% nationally. Housing-cost burden lies in the top 4.8% nationally.
Measured against the nearby ZIPs, expected annual loss runs far higher than the surrounding ZIPs on this measure. Defined simply, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. ZIP 91040, just across the boundary, comes out healthier overall.

Findings that name this ZIP
2 of our published findings list this ZIP code. Each finding compares one published measure against a stated benchmark, and names only the ZIP codes whose estimates are reliable enough to rank. See all surprising findings.
Heavy environment, light chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 9.2 (bottom 10%); chronic-disease standing 91.3 (top 10%) — 82 points apart, heavier on the environment than it is on chronic illness.
Ranked #17,341 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.
Highest-risk tenth

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 0.48 years of 80.0, 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
