What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Fatal road crashes
72.8 per 100,000 residents per year
in the top 1.2% nationally
Lower is healthier
ST97thUS99thDefinition & 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 ›PFAS in drinking water
7.0%
in the bottom 3.3% nationally
Lower is healthier
ST3rdUS3rdDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Slow internet speeds

in the top 3.8% nationally

ST95thUS96thDefinition & source ›
The share of homes whose fastest available download speed is under 10 Mbps.
Full methodology ›Dry extreme heat
80.7 days/year
in the top 4.9% nationally
Lower is healthier
ST50thUS95thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Lithium in drinking water
9.7 µg/L
in the bottom 5.1% nationally
Lower is healthier
ST3rdUS5thDefinition & 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 ›Distance to an emergency room
17.7 mi
in the top 7.4% nationally
Lower is healthier
ST92ndUS93rdDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Medicare-certified hospital with an emergency room.
Full methodology ›Humid extreme heat
135.3 days/year
in the top 8.5% nationally
Lower is healthier
ST57thUS92ndDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Distance to a Superfund site
60.2 mi
in the top 8.6% nationally
Higher is healthier
ST87thUS91stDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›Walkability
2.5 intersections/sq mi
in the bottom 10.6% nationally
Higher is healthier
ST10thUS11thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Radon
0.8 pCi/L
in the bottom 7.4% nationally
Lower is healthier
ST42ndUS7thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›The read
Marquez, Texas (ZIP 77865) ranks in the bottom 47% nationally (16,914th) and the top 31% of Texas (572nd).
A balanced set of signals defines this area, not any single one: modeled pfas resides in the bottom 3.3% nationally, and lithium in drinking water stands in the bottom 5.1% nationally. Distance to a Superfund site sits in the top 8.6% nationally. By contrast, fatal road crashes resides in the top 1.2% nationally, slow internet speeds stands in the top 3.8% nationally, and modeled extreme heat sits in the top 4.9% nationally. Distance to an emergency room resides in the top 7.4% nationally, and modeled humid heat stands in the top 8.5% nationally. Fiber broadband sits at the national minimum, shared with about 19% of ZIPs. Walkability resides in the bottom 10.6% nationally.
Against its neighbors, slow internet speeds runs far higher than the surrounding ZIPs on this measure. For context, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The closest ZIP that ranks healthier overall is ZIP 77856, 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 2.88 years of 86.7, 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.
