Mammography
66.1%
in the bottom 4.1% nationally
Higher is healthier
ST28thUS4thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Fatal road crashes
45.9 per 100,000 residents per year
in the top 5.0% nationally
Lower is healthier
ST89thUS95thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Pharmacy access
0.42 per 1,000 residents
in the top 7.4% nationally
Higher is healthier
ST86thUS93rdDefinition & source ›
The number of pharmacies 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 ›Obesity
44.1%
in the top 6.1% nationally
Lower is healthier
ST86thUS94thDefinition & source ›
The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.
Full methodology ›Dry extreme heat
49.8 days/year
in the top 9.5% nationally
Lower is healthier
ST25thUS91stDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Industrial-pollution burden

Lower is healthier
ST90thUS86thDefinition & 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.
Full methodology ›The read
On the composite measure, Winchester, Oklahoma (ZIP 74421) stands in the bottom 16% nationally (26,830th) and the bottom 49% of Oklahoma (321st).
A profile of give and take, with clear readings each way: pharmacy is in the top 7.4% nationally, and modeled binge drinking registers in the bottom 12.2% nationally. On the other side, modeled mammography lies in the bottom 4.1% nationally, and fatal road crashes is in the top 5.0% nationally. Modeled obesity registers in the top 6.1% nationally, modeled extreme heat lies in the top 9.5% nationally, and distance to a community health center is in the top 11.9% nationally. Modeled industrial-pollution burden registers in the top 14.5% nationally, slow internet speeds lies in the top 17% nationally, and modeled fine-particle is in the top 17% nationally.
For clarity, 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. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. ZIP 74047, just across the boundary, ranks better overall among the ZIPs nearby.

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 0.76 years of 75.5, 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.
