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
70.7%
in the top 1.7% nationally
Lower is healthier
ST97thUS98thDefinition & 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
4.7%
in the top 2.6% nationally
Lower is healthier
ST96thUS97thDefinition & source ›
The share of homes whose fastest available download speed is under 10 Mbps.
Full methodology ›Outer-floodplain exposure
12.5%
in the top 3.1% nationally
Lower is healthier
ST97thUS97thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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 ›Distance to a Superfund site
0.1 mi
in the bottom 3.8% nationally
Higher is healthier
ST6thUS4thDefinition & 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 ›Fatal road crashes
0.6 per 100,000 residents per year
in the bottom 4.1% nationally
Lower is healthier
ST3rdUS4thDefinition & 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 ›Natural-disaster risk
in the top 5.1% nationally
Lower is healthier
ST92ndUS95thDefinition & 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.
Full methodology ›Subsidized affordable housing
387 units
in the top 6.2% nationally
Higher is healthier
ST93rdUS94thDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Dental provider access
1 per 1,000 residents
in the top 6.5% nationally
Higher is healthier
ST97thUS94thDefinition & source ›
The number of dental offices 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 ›Physician access

Higher is healthier
ST94thUS92ndDefinition & source ›
The number of physicians’ offices 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 ›Mental-health provider access
0.12 per 1,000 residents
in the top 8.8% nationally
Higher is healthier
ST94thUS91stDefinition & source ›
The number of mental-health clinics located inside this ZIP’s boundary, per 1,000 residents.

Full methodology ›The read
Judged by its overall standing, ZIP 29902, one of several in Port Royal, South Carolina sits in the top 25% healthiest ZIPs nationally (7,918th) and the top 14.9% of South Carolina (62nd).
A few readings each way define this mixed profile: fatal road crashes lies in the bottom 4.1% nationally. Distance to an emergency room registers at the national minimum, shared with about 11% of ZIPs. Subsidized affordable housing is in the top 6.2% nationally, and dental providers lies in the top 6.5% nationally. Physicians registers in the top 8.2% nationally. Pulling the other way, floodplain exposure is in the top 1.7% nationally, and slow internet speeds lies in the top 2.6% nationally. Outer-floodplain exposure registers in the top 3.1% nationally, and distance to a Superfund site is in the bottom 3.8% nationally. Modeled disaster risk lies in the top 5.1% nationally.
Placed beside its immediate neighbors, slow internet speeds runs far higher than the surrounding ZIPs on this measure. Put plainly, 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. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". A healthier nearby ZIP overall is ZIP 29905, just across the boundary.

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

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.
