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.

PFAS in drinking water

82%

in the top 1.5% nationally

Lower is healthier

ST98th
US99th
Definition & 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.

Mammography

83.9%

in the top 1.4% nationally

Higher is healthier

ST52nd
US99th
Definition & source ›

The estimated share of women aged 50–74 who had a mammogram within the past two years.

Full methodology ›

Outer-floodplain exposure

6.2%

in the top 6.1% nationally

Lower is healthier

ST91st
US94th
Definition & 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 ›

PFOA in drinking water

89.8%

in the top 8.7% nationally

Lower is healthier

ST80th
US91st
Definition & source ›

The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.

Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

Full methodology ›

Poverty rate

2.8%

in the bottom 8.9% nationally

Lower is healthier

ST12th
US9th
Definition & source ›

The share of residents whose income is below the federal poverty line, from the Census Bureau’s American Community Survey.

Full methodology ›

Slow internet speeds

1.2%

in the top 9.3% nationally

Lower is healthier

ST93rd

continue reading

Taken together, the data gives a genuinely mixed reading: modeled mammography settles in the top 1.4% nationally, poverty is in the bottom 8.9% nationally, and modeled uninsured sits in the bottom 2.1% nationally. Household income lands in the top 10.9% nationally, modeled obesity lies in the bottom 14.2% nationally, and modeled food insecurity stands in the bottom 13.5% nationally. On the other side, modeled pfas rests in the top 1.5% nationally, and outer-floodplain exposure registers in the top 6.1% nationally. PFOA in drinking water resides in the top 8.7% nationally, and slow internet speeds settles in the top 9.3% nationally.

Measured against the nearby ZIPs, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined simply, 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. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". ZIP 02715, just across the boundary, comes out healthier overall.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 0.81 years of 80.0, 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.
