Unemployment rate
14.9%

Lower is healthier
ST94thUS96thDefinition & source ›
The share of the civilian labor force that is unemployed.
Full methodology ›Floodplain exposure

Lower is healthier
ST96thUS96thDefinition & 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 ›Arsenic in groundwater
24.2%
in the top 4.7% nationally
Lower is healthier
ST95thUS95thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Loud transportation noise
2.5%
in the top 5.2% nationally
Lower is healthier
ST69thUS95thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 65 decibels — around the volume of normal conversation.
Full methodology ›Binge drinking
11.5%
in the bottom 4.6% nationally
Lower is healthier
ST3rdUS5thDefinition & source ›
The estimated share of adults who report binge drinking — five or more drinks on one occasion for men, four or more for women.

The share of homes whose fastest available download speed is under 10 Mbps.

Lower is healthier
ST72ndUS94thDefinition & 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 ›Dry extreme heat
63.4 days/year
in the top 6.8% nationally
Lower is healthier
ST77thUS93rdDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Elder-services access

in the top 7.5% nationally
Higher is healthier
ST95thUS93rdDefinition & source ›
The number of services for older adults and people with disabilities 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 ›Colon-cancer screening
73.8%

Higher is healthier
ST99thUS95thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›The read
By its overall health score, Rio Vista, California (ZIP 94571) lands in the top 41% healthiest ZIPs nationally (13,068th) and the bottom 46% of California (924th).
A number of signals point in a favorable direction for this area: modeled binge drinking rests in the bottom 4.6% nationally, and elder services is in the top 7.5% nationally. Modeled colon screening stands in the top 5.3% nationally. Working the other way, unemployment settles in the top 3.9% nationally, floodplain exposure lies in the top 4.0% nationally, and modeled arsenic resides in the top 4.7% nationally. Modeled loud transportation noise lands in the top 5.2% nationally, slow internet speeds registers in the top 6.4% nationally, and modeled disaster risk sits in the top 6.5% nationally. Modeled extreme heat rests in the top 6.8% nationally.
Weighed against the ZIPs nearby, park land runs far lower than the surrounding ZIPs on this measure. To translate a couple of terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". Overall, the nearest healthier neighbor is ZIP 94512, 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 0.84 years of 79.4, 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
