Fiber broadband
99.9%
in the top 2.0% nationally
Higher is healthier
ST92ndUS98thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Radon
3.4 pCi/L
in the top 5.6% nationally
Lower is healthier
ST50thUS94thDefinition & 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 ›Child-care access
0.71 per 1,000 residents
in the top 5.1% nationally
Higher is healthier
ST90thUS95thDefinition & 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.

The distance in miles from this ZIP’s edge to the nearest federally funded community health center, which serves patients regardless of ability to pay.

Higher is healthier
ST91stUS86thDefinition & source ›
The number of dental offices 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.

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 ›The read
Lake Mills, Iowa (ZIP 50450), by its overall standing, sits in the top 31% healthiest ZIPs nationally (10,030th) and the top 32% of Iowa (297th).
The profile opens balanced, with readings on either hand: fiber broadband lands in the top 2.0% nationally, childcare is in the top 5.1% nationally, and modeled mammography resides in the top 6.4% nationally. Modeled short sleep rests in the bottom 9.2% nationally, pharmacy lies in the top 10.4% nationally, and dental providers sits in the top 13.8% nationally. Outpatient settles in the top 14.2% nationally. By contrast, modeled radon registers in the top 5.6% nationally, and distance to a community health center stands in the top 9.0% nationally. Modeled fine-particle lands in the top 11.7% nationally.
Defined in plain terms, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. The nearest ZIP ranking healthier overall is ZIP 50436, 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 1.03 years of 79.2, 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.
