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 ›The read
By its overall health score, Dewey, Illinois (ZIP 61840) lands in the top 11.8% healthiest ZIPs nationally (3,757th) and the top 9.9% of Illinois (135th).
Neither strongly one way nor the other, the measures sit mixed: childcare registers in the top 1.2% nationally, and poverty sits at the national minimum. Homeownership rests at the national maximum, and modeled transportation is in the bottom 5.1% nationally. Modeled pfas stands in the bottom 5.6% nationally, and food insecurity settles in the bottom 7.3% nationally. Unemployment lies at the national minimum, shared with about 15% of ZIPs. Households without a vehicle resides at the national minimum, shared with about 16% of ZIPs. Modeled cognitive disability lands in the bottom 6.3% nationally. Against that, modeled arsenic registers in the top 5.1% nationally.
To translate a couple of terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. Overall, the nearest healthier neighbor is ZIP 61822, 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 2.51 years of 87.8, 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. How distance is measured
