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.

Walkability

620 intersections/sq mi

in the top 0.04% nationally

Higher is healthier

ST98th
US99th
Definition & source ›

The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

Full methodology ›

Energy-cost burden

0.77%

in the bottom 0.5% nationally

Lower is healthier

ST14th
US1st
Definition & 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

ST1st
US1st
Definition & 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.

Tree cover

0.00%

at the national minimum

Higher is healthier

ST1st
US1st
Definition & source ›

The share of this ZIP’s land area covered by forest.

Expected annual disaster loss

$0

in the bottom 5.5% nationally

Lower is healthier

ST11th
US5th
Definition & 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 ›

Natural-disaster risk

in the bottom 9.8% nationally

Lower is healthier

ST14th
US10th
Definition & source ›

This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.

The read

Given how limited the coverage is here, for ZIP 20520, 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 that are available, a few readings can be named: walkability stands in the top 0.04% nationally, and modeled energy burden lies in the bottom 0.5% nationally. Floodplain exposure lands at the national minimum, and modeled expected annual loss sits in the bottom 5.5% nationally. Modeled disaster risk is in the bottom 9.8% nationally, and distance to an emergency room settles in the bottom 13.8% nationally. Outer-floodplain exposure resides at the national minimum, shared with about 36% of ZIPs. Park land registers in the top 19% nationally. On the other side, modeled tree cover rests at the national minimum, and distance to a Superfund site stands in the bottom 16% nationally.

Set beside the nearby areas, walkability runs far higher than the surrounding ZIPs on this measure. A note on the terms: expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup.

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.
