Full methodology ›The read
With only part of the picture in hand, ZIP 40203, one of several in Louisville, Kentucky lands in the bottom 0.9% nationally (31,780th) and the bottom 13.4% of Kentucky (643rd), based on limited data; treat as directional.
From the measures on hand, the profile can say a few things: subsidized affordable housing resides in the top 0.6% nationally, walkability lies in the top 1.3% nationally, and childcare settles in the top 4.2% nationally. Against that, modeled transportation noise stands in the top 0.6% nationally, tooth loss is in the top 2.4% nationally, and short sleep rests in the top 2.3% nationally. Households without a vehicle sits in the top 1.9% nationally, and poverty registers in the top 2.4% nationally. Homeownership lands in the bottom 2.5% nationally, and slow internet speeds resides in the top 3.2% nationally.
Compared with the ZIPs that surround it, transportation noise runs far higher than the surrounding ZIPs on this measure. In plain language, transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. ZIP 40204, just across the boundary, ranks healthier 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 0.73 years of 70.9, 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.
