What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Grocery access
0.49 per 1,000 residents
in the top 1.6% nationally
Higher is healthier
ST99thUS98thDefinition & source ›
The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”

Higher is healthier
ST93rdUS92ndDefinition & source ›
The number of outpatient clinics 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.
Full methodology ›Radon
1 pCi/L
in the bottom 18% nationally
Lower is healthier
ST8thUS18thDefinition & 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 ›Dry extreme heat
8.4 days/year
in the top 39% nationally
Lower is healthier

The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›The read
Overall, Courtland, Virginia (ZIP 23837) lands in the top 48% healthiest ZIPs nationally (15,409th) and the bottom 50% of Virginia (438th).
The picture here is genuinely mixed, with readings on both sides: grocery settles in the top 1.6% nationally, and outpatient resides in the top 8.3% nationally. Modeled binge drinking registers in the bottom 10.6% nationally, and civic rests in the top 13.0% nationally. Distance to a nursing home stands at the national minimum, shared with about 27% of ZIPs. Modeled colon screening lies in the top 11.9% nationally, subsidized affordable housing lands in the top 16% nationally, and modeled radon sits in the bottom 18% nationally. On the other side, outer-floodplain exposure is in the top 14.3% nationally, and fatal road crashes settles in the top 15% nationally.
Set beside the nearby areas, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. A note on the terms: radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. For a healthier nearby comparison, ZIP 23878, just across the boundary, ranks better 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 0.67 years of 76.6, 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.
