Unemployment rate
22.9%
in the top 1.5% nationally
Lower is healthier
ST97thUS99thDefinition & source ›
The share of the civilian labor force that is unemployed.
Full methodology ›Fatal road crashes

in the top 2.5% nationally
Lower is healthier
ST95thUS98thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.

The share of households with a broadband internet subscription.

Higher is healthier
ST96thUS96thDefinition & 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 ›Humid extreme heat
147.5 days/year

The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.

Lower is healthier
ST77thUS90thDefinition & 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.

The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.

The read
By the composite health measure, McLain, Mississippi (ZIP 39456) ranks in the bottom 22% nationally (25,077th) and the top 43% of Mississippi (176th).
Several measures weigh most on this area's profile, and they come first: unemployment rests in the top 1.5% nationally, and fatal road crashes stands in the top 2.5% nationally. Home broadband subscription lies in the bottom 3.2% nationally, and modeled humid heat lands in the top 5.4% nationally. Modeled high blood pressure sits in the top 7.7% nationally, floodplain exposure is in the top 9.7% nationally, and poverty settles in the top 10.8% nationally. On the better side, childcare resides in the top 3.8% nationally, and distance to a hazardous-chemical facility registers in the top 10.4% nationally. Distance to a community health center rests at the national minimum, shared with about 23% of ZIPs.
To spell things out, distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". Close by, ZIP 39425, 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 0.81 years of 74.0, 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
