ST97thUS96thDefinition & 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.

The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.

Lower is healthier
ST92ndUS92ndDefinition & 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

The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›The read
On balance, and by the composite measure, Karnes City, Texas (ZIP 78118) ranks in the bottom 19% nationally (26,100th) and the bottom 26% of Texas (1,384th), based on limited data; treat as directional.
The burdens that read clearest in the data come first: modeled uninsured resides in the top 1.5% nationally, and extreme heat lands in the top 1.9% nationally. Modeled humid heat registers in the top 2.9% nationally, and colon screening sits in the bottom 5.3% nationally. Lithium in drinking water rests in the top 8.1% nationally, modeled mammography is in the bottom 8.6% nationally, and home broadband subscription stands in the bottom 10.1% nationally. Modeled fair or poor health settles in the top 11.3% nationally. Better still, mental-health providers lies in the top 4.1% nationally. Distance to a community health center resides at the national minimum, shared with about 23% of ZIPs.
In plainer terms, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors.

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 1.11 years of 76.5, 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.
