US99thDefinition & source ›
The share of households with a broadband internet subscription.
Full methodology ›Floodplain exposure
0.00%
at the national minimum
Lower is healthier
ST1stUS1stDefinition & 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 ›Energy-cost burden
1.0%
in the bottom 1.2% nationally
Lower is healthier
ST67thUS1stDefinition & 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 ›Tree cover
0.00%
at the national minimum
Higher is healthier
ST1stUS1stDefinition & source ›
The share of this ZIP’s land area covered by forest.
Full methodology ›PFAS in drinking water
100%
at the national maximum
Lower is healthier
ST99thUS99thDefinition & source ›
The share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were 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
On the data available so far, for ZIP 20317, one of several in Washington, District of Columbia, health standing is not ranked here — the available data is too limited to place it confidently.
The available readings suggest a handful of things about this area: poverty settles at the national minimum, and homeownership rests at the national maximum. Home broadband subscription lands at the national maximum, and floodplain exposure settles at the national minimum. Modeled energy burden rests in the bottom 1.2% nationally. Distance to an emergency room lands at the national minimum, shared with about 11% of ZIPs. By contrast, modeled air-toxics cancer risk settles in the top 0.5% nationally, slow internet speeds rests in the top 1.3% nationally, and modeled tree cover lands at the national minimum. PFAS in drinking water settles at the national maximum.
Against its neighbors, slow internet speeds runs far higher than the surrounding ZIPs on this measure. For context, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain".

Life expectancyNCHS / RWJF USALEEP · model-based
| Measure | Value | US median (p10–p90) | DC median (p10–p90) |
|---|---|---|---|
| Life expectancy at birth | 79.9 yr ± 1.08 | 78.9 yr (74.7–82.8) n=31,308 | 80.1 yr (74.0–84.9) n=39 |
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 1.08 years of 79.9, and it’s very unlikely to be off by more than twice that.
