Dry extreme heat
83.7 days/year
in the top 4.5% nationally
Lower is healthier
ST54thUS96thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›PFAS in drinking water

in the bottom 5.5% nationally
Lower is healthier
ST7thUS5thDefinition & 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 ›Humid extreme heat
145.3 days/year
in the top 6.0% nationally
Lower is healthier
ST64thUS94thDefinition & 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 ›Elder-services access
0.17 per 1,000 residents
in the top 8.6% nationally
Higher is healthier
ST94thUS91stDefinition & source ›
The number of services for older adults and people with disabilities 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 ›Fatal road crashes
34.7 per 100,000 residents per year
in the top 9.8% nationally
Lower is healthier
ST83rdUS90thDefinition & 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 ›Transportation noise
8.9%
in the top 10.3% nationally
Lower is healthier
ST91stUS90thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›The read
In overall standing, Caldwell, Texas (ZIP 77836) comes out in the bottom 38% nationally (19,780th) and the top 40% of Texas (745th).
The profile opens balanced, with readings on either hand: distance to an emergency room resides at the national minimum, shared with about 11% of ZIPs. Modeled pfas rests in the bottom 5.5% nationally, and elder services lies in the top 8.6% nationally. Distance to a community health center sits at the national minimum, shared with about 23% of ZIPs. Distance to a nursing home settles at the national minimum, shared with about 27% of ZIPs. By contrast, modeled extreme heat registers in the top 4.5% nationally, and humid heat stands in the top 6.0% nationally. Fatal road crashes lands in the top 9.8% nationally, and modeled transportation noise is in the top 10.3% nationally. Modeled loud transportation noise resides in the top 12.1% nationally.
In plain terms, 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. 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. The nearest healthier ZIP overall is ZIP 77807, 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 0.76 years of 78.2, 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.
