Markham, Virginia (ZIP 22643), in overall standing, comes out in the top 16% healthiest ZIPs nationally (5,193rd) and the top 18% of Virginia (159th).
A few readings each way define this mixed profile: modeled colon screening stands in the top 0.8% nationally, home broadband subscription resides at the national maximum, and modeled pfas sits in the bottom 3.5% nationally. Modeled housing insecurity stands in the bottom 5.4% nationally, utility shutoff resides in the bottom 5.7% nationally, and transportation sits in the bottom 6.7% nationally. Pulling the other way, modeled loud transportation noise stands in the top 0.5% nationally, and crowded housing resides in the top 0.7% nationally. Housing-cost burden sits in the top 2.1% nationally, and modeled transportation noise stands in the top 3.1% nationally.
Set within its surrounding area, loud transportation noise runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, 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. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. The closest healthier ZIP overall is ZIP 22639, 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 2.38 years of 82.2, 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.
