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.
Energy-cost burden
0.77%
in the bottom 0.5% nationally
Lower is healthier
ST25thUS1stDefinition & 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 ›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 ›Tree cover
0.00%

ST1stUS1stDefinition & source ›
The share of this ZIP’s land area covered by forest.

in the bottom 5.7% nationally
Lower is healthier
ST14thUS6thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.
Full methodology ›Distance to a Superfund site
1.2 mi
in the bottom 7.7% nationally
Higher is healthier
ST16thUS8thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›The read
With the picture still incomplete, for ZIP 20540, one of several in Washington, District of Columbia, health standing is not ranked here — the available data is too limited to place it confidently.
From the measures on hand, the profile can say a few things: modeled energy burden registers in the bottom 0.5% nationally, floodplain exposure lands at the national minimum, and modeled expected annual loss resides in the bottom 5.7% nationally. Modeled disaster risk lies in the bottom 10.2% nationally. Outer-floodplain exposure settles at the national minimum, shared with about 36% of ZIPs. Walkability stands in the top 18% nationally, and distance to a community health center is in the bottom 30% nationally. Against that, modeled tree cover rests at the national minimum, and distance to a Superfund site sits in the bottom 7.7% nationally. Park land registers at the national minimum, shared with about 48% of ZIPs.
Set against the neighboring ZIPs, park land runs far lower than the surrounding ZIPs on this measure. In everyday language, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake.

| Life expectancy at birth | 82.7 yr ± 2.74 | 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 2.74 years of 82.7, and it’s very unlikely to be off by more than twice that.
