ST98thUS96thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Outer-floodplain exposure

ST98thUS94thDefinition & 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.

ST13thUS5thDefinition & 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 ›The read
By its overall health score, Churchton, Maryland (ZIP 20733) lands in the top 9.5% healthiest ZIPs nationally (3,020th) and the top 27% of Maryland (125th).
The measures split the difference for this area: modeled mammography registers in the top 0.5% nationally, and transportation noise sits in the bottom 6.5% nationally. Fiber broadband rests in the top 6.7% nationally, and household income is in the top 7.7% nationally. Modeled colon screening stands in the top 4.8% nationally, and transportation settles in the bottom 7.6% nationally. Households without a vehicle lies at the national minimum, shared with about 16% of ZIPs. Against that, modeled pfas resides in the top 3.6% nationally, outer-floodplain exposure lands in the top 5.6% nationally, and unemployment registers in the top 7.2% nationally.
Weighed against the ZIPs nearby, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. To translate a couple of terms, 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. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Overall, the nearest healthier neighbor is ZIP 20751, 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 1.26 years of 78.6, 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. How distance is measured
