Arsenic in groundwater
17.8%
in the top 7.7% nationally
Lower is healthier
ST80thUS92ndDefinition & 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.
Full methodology ›Radon
3 pCi/L
in the top 10.2% nationally
Lower is healthier
ST91stUS90thDefinition & 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.

1.4 mi

Higher is healthier
ST6thUS8thDefinition & 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.

The estimated share of adults who usually sleep less than seven hours in a 24-hour period.

Full methodology ›The read
Overall, Catlin, Illinois (ZIP 61817) lands in the top 37% healthiest ZIPs nationally (11,751st) and the top 36% of Illinois (486th).
A handful of measures stand out most sharply across the profile here: floodplain exposure rests in the bottom 10.8% nationally. Crowded housing stands at the national minimum, shared with about 29% of ZIPs. Fatal road crashes lies in the bottom 16% nationally, and childcare lands in the top 16% nationally. On the other side, modeled arsenic sits in the top 7.7% nationally, modeled radon is in the top 10.2% nationally, and distance to a Superfund site settles in the bottom 8.5% nationally. Fiber broadband resides at the national minimum, shared with about 19% of ZIPs. Lead in tap water registers in the top 14.1% nationally. Distance to a hazardous-chemical facility rests at the national minimum, shared with about 31% of ZIPs.
A note on the terms: arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. For a healthier nearby comparison, ZIP 61849, about 6.7 miles away, ranks better overall.

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 0.77 years of 77.4, 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.
