Industrial-pollution burden

Lower is healthier
ST98thUS99thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.

The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.

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.

The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Obesity

The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.
Full methodology ›Energy-cost burden

in the bottom 5.5% nationally
Lower is healthier
ST6thUS5thDefinition & 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 ›Lead in tap water
0.00012 ppb
in the bottom 9.4% 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 ›Binge drinking

The estimated share of adults who report binge drinking — five or more drinks on one occasion for men, four or more for women.

Full methodology ›The read
Overall, ZIP 89441, one of several in Sparks, Nevada places in the top 24% healthiest ZIPs nationally (7,585th) and the top 19% of Nevada (32nd).
The measures land in both directions, and neither dominates: household income settles in the top 6.7% nationally, and modeled obesity sits in the bottom 10.0% nationally. Modeled energy burden lies in the bottom 5.5% nationally, and lead in tap water rests in the bottom 9.4% nationally. Homeownership resides in the top 11.9% nationally, poverty is in the bottom 13.2% nationally, and modeled humid heat lands in the bottom 13.5% nationally. Pulling the other way, modeled industrial-pollution burden stands in the top 0.6% nationally, fine-particle registers in the top 0.7% nationally, and disaster risk settles in the top 5.1% nationally.
Beside the areas that surround it, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Among nearby ZIPs, the nearest healthier one overall is ZIP 89436, 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 1.10 years of 80.8, 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.
