The estimated share of adults aged 18–64 with no current health-insurance coverage.

ST97thUS99thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms 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.

The number of outpatient 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.

Full methodology ›The read
On the composite measure, Center, Colorado (ZIP 81125) stands in the bottom 42% nationally (18,680th) and the bottom 19% of Colorado (407th), based on limited data; treat as directional.
The weightiest signals in the profile are worth naming up front: modeled uninsured lands in the top 2.7% nationally, and arsenic settles in the top 1.4% nationally. Modeled tree cover rests at the national minimum, and walkability lands in the bottom 4.9% nationally. Unemployment settles in the top 5.3% nationally, and modeled vision disability rests in the top 7.2% nationally. More positively, modeled air-toxics cancer risk lands in the bottom 2.8% nationally, outpatient settles in the top 4.3% nationally, and modeled industrial-pollution burden rests in the bottom 4.5% nationally. Childcare lands in the top 5.7% nationally.
Set beside the wider area around it, arsenic runs far higher than the surrounding ZIPs on this measure. For clarity, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. ZIP 81131, 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 1.21 years of 81.8, 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.
