Civic-institution access

Higher is healthier
ST95thUS91stDefinition & source ›
The number of civic and social organizations 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
2.4 pCi/L
in the top 23% nationally
Lower is healthier
ST93rdUS77thDefinition & 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 ›The read
Overall, Friendsville, Tennessee (ZIP 37737) places in the bottom 39% nationally (19,538th) and the top 22% of Tennessee (138th).
The data opens on a genuinely even set of readings: civic lies in the top 8.9% nationally, and modeled arsenic rests in the bottom 11.1% nationally. Modeled transportation noise resides in the bottom 17% nationally, and housing-cost burden is in the bottom 18% nationally. Outer-floodplain exposure lands at the national minimum, shared with about 36% of ZIPs. Modeled energy burden stands in the bottom 21% nationally. On the other side, modeled humid heat registers in the top 18% nationally. Childcare settles at the national minimum, shared with about 42% of ZIPs. Modeled high cholesterol sits in the top 19% nationally. Park land lies at the national minimum, shared with about 48% of ZIPs.
Beside the areas that surround it, park land runs far lower than the surrounding ZIPs on this measure. For readers new to these terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Among nearby ZIPs, the nearest healthier one overall is ZIP 37772, 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 0.98 years of 77.6, 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.
