Where America's Urgent Care Deserts Are: What 13,448 Clinics Reveal
Updated : Added the population-adjusted state ranking, using U.S. Census Bureau American Community Survey 2020–2024 5-year population estimates (Data Profile DP05). Source added to the list below.
When a rural town loses its walk-in clinic, where does a Saturday-night fever go? We took every urgent care organization registered in the federal NPPES provider registry — 13,448 clinics, 12,127 of them precisely geocoded — and measured the distance from each clinic to its nearest alternative. The result is the clearest picture we know of where American urgent care access is deep, where it's thin, and where a single clinic is all that stands between a community and the ER.
The headline numbers
- 1,872 towns — 46% of every city with urgent care at all — depend on exactly one clinic. If it closes, the town's walk-in tier is gone.
- 203 clinics have no alternative within 25 miles. For 43 of them, the nearest other urgent care is over 50 miles away.
- The national median distance between neighboring clinics is just 0.6 miles — urgent care clusters hard in metros while entire regions go without.
The most isolated urgent cares in America
Miles shown are straight-line distance to the nearest other registered urgent care clinic:
- 132 mi
- Kodiak, Alaska — an island community's only walk-in clinic
- 130 mi
- Ainsworth, Nebraska — the Sandhills' lone urgent care
- 109 mi
- Conrad, Montana
- 103 mi
- Liberal, Kansas
- 102 mi
- Winnemucca, Nevada — the I-80 corridor's only stop for 100+ miles
- 89 mi
- Mandan and Dickinson, North Dakota
- 87 mi
- Jamestown, North Dakota
- 84 mi
- Iron Mountain, Michigan — the Upper Peninsula gap
- 84 mi
- Denali Park, Alaska
- 83 mi
- Goodland, Kansas and McCook, Nebraska
These aren't underperforming businesses — they're load-bearing infrastructure. Each one is the difference between a 15-minute drive and a multi-hour round trip (or an ER bill) for stitches, strep tests, and X-rays across an enormous service area.
Where the clinics concentrate
The flip side of rural scarcity is metro saturation. The most urgent-care-dense cities in the registry:
Houston alone registers more urgent care organizations than North Dakota, Vermont, Montana, South Dakota, and Iowa combined (175 vs. 105). The five thinnest states by registered clinic count: North Dakota (14), Vermont (15), Montana (20), South Dakota (24), and Iowa (32).
Adjusted for population: clinics per 100,000 residents
Raw counts mostly track population, so we divided each state's registered urgent care locations by its U.S. Census Bureau population (American Community Survey 2020–2024 5-year estimates, Data Profile DP05). Nationally, the registry works out to about 4.0 urgent care locations per 100,000 residents — but the spread between states is nearly eightfold.
Read the low end carefully. This count only includes organizations registered under the federal Urgent Care Clinic/Center category — walk-in care delivered by hospital outpatient clinics, retail clinics, or primary care practices registered under other categories isn't in these numbers, and how common that is varies by state. Wyoming, meanwhile, reaches the top with just 46 registered locations because it has the smallest population of any state. So a low figure flags a state worth a closer look, not proof that walk-in care is absent. Each state's page now shows its own figure alongside Census population and insurance data — for example, Texas, where 17.1% of residents lack health insurance.
Why this matters
Urgent care exists to absorb the enormous middle ground between a doctor's appointment next week and a $2,600 emergency room visit tonight (see our cost breakdown). Where the walk-in tier is missing, that middle ground collapses: minor injuries and infections either wait — and worsen — or flow into emergency departments at roughly ten times the cost. The 1,872 single-clinic towns in our data are one retirement, one lease dispute, or one staffing crisis away from joining the desert map.
Methodology & honest limits
Source: every organization registered in the federal NPPES provider registry under the Urgent Care Clinic/Center taxonomy (261QU0200X) as of August 2026, de-duplicated by name and address — 13,448 locations. Geocoding: U.S. Census Bureau batch geocoder; 12,127 clinics (90%) resolved to exact coordinates, and isolation figures use only geocoded clinics.Per-capita figures divide each state's registered locations by its U.S. Census Bureau ACS 2020–2024 5-year population estimate. Distances are straight-line (haversine), so real driving distances are longer — our isolation numbers are conservative. Limits: NPPES reflects registrations, which can lag openings, closures, and relocations; some registered organizations operate multiple sites under one record, and hospital ERs, retail clinics, and primary care practices that absorb walk-ins are not counted. Treat these figures as a registry-based floor for the walk-in tier, not a clinical access study. The underlying data is browsable clinic-by-clinic across this directory —every state, every city, every listing — and journalists or researchers are welcome to cite this analysis with a link.
