Nitrate in drinking water
32.7%
in the top 1.5% nationally
Lower is healthier
ST83rdUS99thDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams 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 ›Lithium in drinking water
120 µg/L
in the top 1.7% nationally
Lower is healthier
ST99thUS98thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
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 ›Mammography
66%
in the bottom 4.0% nationally
Higher is healthier
ST27thUS4thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Dry extreme heat
64.9 days/year
in the top 6.6% nationally
Lower is healthier
ST66thUS93rdDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Subsidized affordable housing

in the top 6.7% nationally
Higher is healthier
ST98thUS93rdDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Natural-disaster risk
in the top 6.7% nationally
Lower is healthier
ST93rdUS93rdDefinition & 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 ›Expected annual disaster loss
$0
in the top 7.3% nationally
Lower is healthier
ST94thUS93rdDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.
Full methodology ›Colon-cancer screening
57.3%
in the bottom 7.9% nationally
Higher is healthier
ST17thUS8thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›Obesity

The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.
Full methodology ›The read
In its overall standing, El Reno, Oklahoma (ZIP 73036) lands in the bottom 16% nationally (26,976th) and the bottom 48% of Oklahoma (332nd).
This area's pressures are easy to read across the measures: modeled nitrate is in the top 1.5% nationally, lithium in drinking water sits in the top 1.7% nationally, and modeled mammography lands in the bottom 4.0% nationally. Modeled extreme heat lies in the top 6.6% nationally, disaster risk stands in the top 6.7% nationally, and expected annual loss rests in the top 7.3% nationally. Modeled colon screening registers in the bottom 7.9% nationally, and obesity resides in the top 8.3% nationally. On the brighter side, subsidized affordable housing settles in the top 6.7% nationally. Distance to a nursing home is at the national minimum, shared with about 27% of ZIPs.
Against the wider neighborhood, lithium in drinking water runs far higher than the surrounding ZIPs on this measure. Put simply, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. On the overall standing, ZIP 73047, just across the boundary, ranks healthier.

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 0.62 years of 75.0, 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
