Median household income
$161,833
in the top 2.8% nationally
Higher is healthier
ST86thUS97thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Lithium in drinking water
10 µg/L
in the bottom 7.6% nationally
Lower is healthier
ST11thUS8thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
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
2.4%
in the bottom 8.0% nationally
Lower is healthier
ST17thUS8thDefinition & source ›
The share of residents whose income is below the federal poverty line, from the Census Bureau’s American Community Survey.
Full methodology ›Child-care access
0.52 per 1,000 residents
in the top 9.7% nationally
Higher is healthier
ST94thUS90thDefinition & 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 ›Independent-living disability
6.0%
in the bottom 9.2% nationally
Lower is healthier
ST29thUS9thDefinition & source ›
The estimated share of adults who have difficulty doing errands alone, such as visiting a doctor’s office, because of a physical, mental, or emotional condition.
Full methodology ›Industrial-pollution burden
in the bottom 12.6% nationally
Lower is healthier
ST6thUS13thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Tooth loss
7.1%
in the bottom 8.7% nationally
Lower is healthier
ST29thUS9thDefinition & source ›
The estimated share of adults aged 65 and older who have lost all of their natural teeth.
Full methodology ›Tree cover
61.5%
in the top 14.0% nationally
Higher is healthier
ST95thUS86thDefinition & source ›
The share of this ZIP’s land area covered by forest.
Full methodology ›Fatal road crashes
27.6 per 100,000 residents per year
in the top 16% nationally
Lower is healthier
ST92ndUS84thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Arsenic in groundwater
1.7%
in the bottom 18% nationally
Lower is healthier
ST3rdUS18thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
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 ›The read
Sunderland, Maryland (ZIP 20689), in overall standing, comes out in the top 10.1% healthiest ZIPs nationally (3,211th) and the top 30% of Maryland (137th).
An even profile, with readings pulling both ways: household income stands in the top 2.8% nationally, lithium in drinking water resides in the bottom 7.6% nationally, and poverty sits in the bottom 8.0% nationally. Childcare stands in the top 9.7% nationally, homeownership resides in the top 11.6% nationally, and modeled independent living disability sits in the bottom 9.2% nationally. Modeled cognitive disability stands in the bottom 10.8% nationally, and industrial-pollution burden resides in the bottom 12.6% nationally. Modeled hearing disability sits in the bottom 12.1% nationally. Against that, fiber broadband stands at the national minimum, shared with about 19% of ZIPs.
Set within its surrounding area, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, for reference, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. The closest healthier ZIP overall is ZIP 20736, 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 1.64 years of 81.8, 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
