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.
Child-care access
1.6 per 1,000 residents
in the top 0.6% nationally
Higher is healthier
ST99thUS99thDefinition & source ›
The number of child day-care services 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 ›Nitrate in drinking water
6.2%
in the top 3.8% nationally
Lower is healthier
ST95thUS96thDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams 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.
Full methodology ›Walkability
1.8 intersections/sq mi
in the bottom 6.0% nationally
Higher is healthier
ST29thUS6thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Distance to a Superfund site
59.2 mi
in the top 8.9% nationally
Higher is healthier
ST88thUS91stDefinition & 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 ›Mammography
68.7%
in the bottom 9.4% nationally
Higher is healthier
ST40thUS9thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Housing-cost burden
13.0%
in the bottom 14.2% nationally
Lower is healthier
ST8thUS14thDefinition & source ›
The share of households spending 30% or more of their income on housing.
Full methodology ›Outer-floodplain exposure
1.7%
in the top 17% nationally
Lower is healthier
ST90thUS83rdDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Floodplain exposure
14.8%
in the top 26% nationally
Lower is healthier
ST97thUS74thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›The read
Iliff, Colorado (ZIP 80736) ranks in the bottom 47% nationally (17,049th) and the bottom 24% of Colorado (380th).
Several signals sit on each side of the ledger here: childcare rests in the top 0.6% nationally. Unemployment lands at the national minimum, shared with about 15% of ZIPs. Distance to a Superfund site settles in the top 8.9% nationally, and modeled obesity rests in the bottom 12.4% nationally. Working the other way, modeled nitrate lands in the top 3.8% nationally, and walkability settles in the bottom 6.0% nationally. Fiber broadband rests at the national minimum, shared with about 19% of ZIPs. Modeled mammography lands in the bottom 9.4% nationally, radon settles in the top 11.6% nationally, and tree cover rests in the bottom 10.2% nationally.
For context, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. The closest ZIP that ranks healthier overall is ZIP 80726, 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 1.13 years of 77.9, 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.
