Median household income

Higher is healthier
ST92ndUS96thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Obesity
25.4%
in the bottom 6.2% nationally
Lower is healthier
ST5thUS6thDefinition & source ›
The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.
Full methodology ›Energy-cost burden

in the bottom 2.0% nationally
Lower is healthier
ST5thUS2ndDefinition & 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 ›Fatal road crashes
1.9 per 100,000 residents per year
in the bottom 6.7% nationally
Lower is healthier
ST8thUS7thDefinition & 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 ›Tooth loss
4.9%
in the bottom 2.0% nationally
Lower is healthier
ST4thUS2ndDefinition & source ›
The estimated share of adults aged 65 and older who have lost all of their natural teeth.
Full methodology ›Civic-institution access

Higher is healthier
ST94thUS92ndDefinition & 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 ›Subsidized affordable housing

in the top 7.8% nationally
Higher is healthier
ST89thUS92ndDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.

Higher is healthier
ST93rdUS92ndDefinition & source ›
The number of dental offices located 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 ›Fiber broadband

in the top 8.3% nationally
Higher is healthier
ST92ndUS92ndDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›PFOA in drinking water
90.4%
in the top 8.5% nationally
Lower is healthier
ST86thUS92ndDefinition & 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 ›The read
Overall, ZIP 20191, one of several in Reston, Virginia places in the top 3.0% healthiest ZIPs nationally (961st) and the top 5.7% of Virginia (49th).
The measures land in both directions, and neither dominates: household income is in the top 3.8% nationally, and modeled obesity lands in the bottom 6.2% nationally. Modeled energy burden stands in the bottom 2.0% nationally, and fatal road crashes registers in the bottom 6.7% nationally. Modeled tooth loss settles in the bottom 2.0% nationally, civic sits in the top 7.6% nationally, and subsidized affordable housing lies in the top 7.8% nationally. Dental providers rests in the top 7.9% nationally, and fiber broadband resides in the top 8.3% nationally. Pulling the other way, PFOA in drinking water is in the top 8.5% nationally.
Beside the areas that surround it, park land runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Energy burden is the share of household income that goes to home energy bills. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Among nearby ZIPs, the nearest healthier one overall is ZIP 20171, 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 1.01 years of 81.0, 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.
