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.
Floodplain exposure
78.2%
in the top 1.2% nationally
Lower is healthier
ST99thUS99thDefinition & 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 ›Transit access
8.8 per 1,000 residents
in the top 1.6% nationally
Higher is healthier
ST99thUS98thDefinition & source ›
The number of public-transit stops 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 ›Grocery access
0.32 per 1,000 residents
in the top 3.4% nationally
Higher is healthier
ST98thUS97thDefinition & 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 ›Tree cover

Higher is healthier
ST1stUS1stDefinition & source ›
The share of this ZIP’s land area covered by forest.
Full methodology ›Recreation access
1.3 per 1,000 residents
in the top 5.1% nationally
Higher is healthier
ST97thUS95thDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — 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 ›Housing-cost burden
41.3%
in the top 8.7% nationally
Lower is healthier
ST92ndUS91stDefinition & source ›
The share of households spending 30% or more of their income on housing.
Full methodology ›Fatal road crashes
35.8 per 100,000 residents per year
in the top 9.1% nationally
Lower is healthier
ST84thUS91stDefinition & 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 ›High cholesterol
43.9%
in the top 7.2% nationally
Lower is healthier
ST95thUS93rdDefinition & source ›
The estimated share of adults with high cholesterol, among those who have ever been screened for it.

Full methodology ›The read
Port Aransas, Texas (ZIP 78373), overall, ranks in the top 36% healthiest ZIPs nationally (11,665th) and the top 19% of Texas (355th).
This area's measures are easy to read as a mixed set: transit stands in the top 1.6% nationally, grocery rests in the top 3.4% nationally, and recreation registers in the top 5.1% nationally. Set against that, floodplain exposure resides in the top 1.2% nationally, modeled tree cover settles at the national minimum, and housing-cost burden is in the top 8.7% nationally. Fatal road crashes sits in the top 9.1% nationally, and outer-floodplain exposure lands in the top 10.1% nationally. Modeled high cholesterol lies in the top 7.2% nationally, and distance to a nursing home stands in the top 13.4% nationally.
Measured against the nearby ZIPs, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. Defined simply, floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". ZIP 78419, about 3.1 miles away, comes out healthier overall.

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 2.04 years of 76.1, 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.
