Outer-floodplain exposure
25%
in the top 1.6% nationally
Lower is healthier
ST98thUS98thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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.
Full methodology ›Radon
3.4 pCi/L
in the top 6.1% nationally
Lower is healthier
ST43rdUS94thDefinition & 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 ›Housing-cost burden
8.4%
in the bottom 7.7% nationally
Lower is healthier
ST18thUS8thDefinition & source ›
The share of households spending 30% or more of their income on housing.
Full methodology ›Child-care access
0.56 per 1,000 residents
in the top 8.3% nationally
Higher is healthier
ST76thUS92ndDefinition & 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 ›Floodplain exposure
21.6%
in the top 16% nationally
Lower is healthier
ST94thUS84thDefinition & 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.
Full methodology ›Median household income
$106,250
in the top 15% nationally
Higher is healthier
ST92ndUS85thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Energy-cost burden
2.5%
in the bottom 25% nationally
Lower is healthier
ST6thUS25thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Obesity
32.7%
in the bottom 27% nationally
Lower is healthier
ST7thUS27thDefinition & source ›
The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.
Full methodology ›Loud transportation noise
0.60%
in the top 32% nationally
Lower is healthier
ST95thUS68thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 65 decibels — around the volume of normal conversation.
Full methodology ›The read
Jefferson, South Dakota (ZIP 57038), by its composite score, sits in the top 22% healthiest ZIPs nationally (7,155th) and the top 19% of South Dakota (69th).
The data opens on a genuinely even set of readings: housing-cost burden resides in the bottom 7.7% nationally, and childcare is in the top 8.3% nationally. Poverty lands in the bottom 10.4% nationally, and homeownership stands in the top 14.1% nationally. On the other side, outer-floodplain exposure registers in the top 1.6% nationally, modeled radon settles in the top 6.1% nationally, and modeled fine-particle sits in the top 11.7% nationally. Modeled binge drinking lies in the top 11.2% nationally, slow internet speeds rests in the top 15% nationally, and floodplain exposure resides in the top 16% nationally.
Next to the surrounding area, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain".

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 1.36 years of 82.4, 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.
