in the top 9.4% nationally
Higher is healthier
ST80thUS91stDefinition & source ›
The number of civic and social organizations inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Lead in tap water
0.00017 ppb
in the bottom 9.5% nationally
Lower is healthier
US9thDefinition & source ›
The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Floodplain exposure
25.1%
in the top 13.0% nationally
Lower is healthier
ST91stUS87thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›The read
Lockeford, California (ZIP 95237), on the composite measure, lands in the top 45% healthiest ZIPs nationally (14,493rd) and the bottom 43% of California (987th).
The readings split fairly evenly between strengths and concerns: civic registers in the top 9.4% nationally, and lead in tap water lands in the bottom 9.5% nationally. Working the other way, modeled loud transportation noise resides in the top 1.3% nationally, extreme heat lies in the top 3.8% nationally, and air-toxics cancer risk settles in the top 4.5% nationally. Modeled tree cover stands at the national minimum, and fine-particle is in the top 6.4% nationally. Modeled transportation noise rests in the top 7.9% nationally. Fiber broadband sits at the national minimum, shared with about 19% of ZIPs. Floodplain exposure registers in the top 13.0% nationally.
Set against the neighboring ZIPs, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. In everyday language, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. A healthier neighbor overall sits at ZIP 95227, just across the boundary.

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 1.02 years of 78.5, 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
