What defines this ZIP

Humid extreme heat
3.2 days/year
in the bottom 2.0% nationally
Lower is healthier
ST4thUS2ndDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Walkability
190 intersections/sq mi
in the top 3.1% nationally
Higher is healthier
ST94thUS97thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Lead in tap water
0 ppb
at the national minimum
Lower is healthier
US1stDefinition & 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 ›Housing-cost burden
45.3%
in the top 5.3% nationally
Lower is healthier
ST79thUS95thDefinition & source ›
The share of households spending 30% or more of their income on housing.
Full methodology ›Mental-health provider access
0.16 per 1,000 residents
in the top 6.2% nationally
Higher is healthier
ST92ndUS94thDefinition & source ›
The number of mental-health clinics located 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 ›Natural-disaster risk
in the top 6.3% nationally
Lower is healthier
ST73rdUS94thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Energy-cost burden
1.6%
in the bottom 5.4% nationally
Lower is healthier
ST23rdUS5thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Outpatient-care access
0.47 per 1,000 residents
in the top 8.7% nationally
Higher is healthier
ST87thUS91stDefinition & source ›
The number of outpatient clinics located 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 ›Homeownership rate
50.5%
in the bottom 9.3% nationally
Higher is healthier
ST27thUS9thDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.
Full methodology ›Radon
0.7 pCi/L
in the bottom 4.8% nationally
Lower is healthier
ST4thUS5thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›The read
In overall standing, Grover Beach, California (ZIP 93433) comes out in the top 29% healthiest ZIPs nationally (9,294th) and the top 44% of California (763rd).
The profile opens balanced, with readings on either hand: modeled humid heat stands in the bottom 2.0% nationally, walkability lands in the top 3.1% nationally, and lead in tap water is at the national minimum. Mental-health providers resides in the top 6.2% nationally, modeled energy burden rests in the bottom 5.4% nationally, and outpatient lies in the top 8.7% nationally. Modeled extreme heat sits at the national minimum, shared with about 19% of ZIPs. By contrast, housing-cost burden settles in the top 5.3% nationally, and modeled disaster risk registers in the top 6.3% nationally. Homeownership stands in the bottom 9.3% nationally.
Relative to the ZIPs around it, walkability runs far higher than the surrounding ZIPs on this measure. In plain terms, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. The nearest healthier ZIP overall is ZIP 93420, 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 0.81 years of 79.3, 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
