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.

Mammography

60.2%

in the bottom 0.8% nationally

Higher is healthier

ST1st
US1st
Definition & source ›

The estimated share of women aged 50–74 who had a mammogram within the past two years.

Full methodology ›

Grocery access

0.83 per 1,000 residents

in the top 0.6% nationally

Higher is healthier

ST99th
US99th
Definition & source ›

The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”

Full methodology ›

Fine-particle (PM2.5) exceedance

4.4%

in the top 1.3% nationally

Lower is healthier

ST99th
US99th
Definition & source ›

The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.

Unemployment rate

23.1%

in the top 1.5% nationally

Lower is healthier

ST99th

Definition & source ›

The share of the civilian labor force that is unemployed.

Outpatient-care access

0.83 per 1,000 residents

in the top 2.9% nationally

Higher is healthier

ST98th
US97th
Definition & source ›

The number of outpatient clinics 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 ›

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.

Full methodology ›

Slow internet speeds

in the top 5.5% nationally

Lower is healthier

ST94th
US95th
Definition & source ›

The share of homes whose fastest available download speed is under 10 Mbps.

Lower is healthier

ST82nd
US94th
Definition & source ›

The distance in miles from this ZIP’s edge to the nearest Medicare- or Medicaid-certified nursing home.

ST8th
US7th

Several measures weigh most on this area's profile, and they come first: modeled mammography sits in the bottom 0.8% nationally, and fine-particle is in the top 1.3% nationally. Unemployment settles in the top 1.5% nationally, and slow internet speeds resides in the top 5.5% nationally. Distance to a nursing home registers in the top 6.5% nationally. On the better side, grocery rests in the top 0.6% nationally, outpatient stands in the top 2.9% nationally, and floodplain exposure lies at the national minimum. Modeled industrial-pollution burden lands in the bottom 7.3% nationally, and transportation noise sits in the bottom 7.7% nationally.

Read against the ZIPs closest to it, grocery runs far higher than the surrounding ZIPs on this measure. To spell things out, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". Close by, ZIP 99122, just across the boundary, ranks healthier overall.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 2.38 years of 80.0, 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.
