- South Carolina's 10 smallest counties (under 25,000 people) have 8.3 service establishments per 1,000 residents, about half the 16.1 in the eight largest counties.
- Physician offices run from 1.9 per 10,000 residents in the smallest counties to 5.0 in the largest; dental offices from 0.9 to 3.6.
- Seven counties have fewer than three employer dental offices published by the Census, including Fairfield, Union and Allendale.
- Population is moving the same direction: the median small county shrank 1.3% from 2020 to 2024, while the median large county grew 8.0%.
- Businesses with a mobile, remote or online booking model can reach rural customers that few local competitors serve.
How do rural South Carolina businesses compare with urban ones?
Rural South Carolina has far fewer service businesses per person. We grouped the state's 46 counties into four tiers by 2024 population and counted employer establishments in the service sectors (information, finance and insurance, real estate, professional services, administrative support, education, health care, arts and recreation, hospitality and food, and repair and personal services). The smallest tier has 121 residents per service establishment. The largest has 62.
The gap compounds. The eight counties of 250,000 or more hold 56.5% of the state's population but 64.5% of its county-assigned service establishments. The 10 counties under 25,000 hold 3.0% of residents and 1.8% of establishments. Service jobs follow the same pattern: 7.4 per 100 residents in the smallest counties against 22.7 in the largest.
| County size (2024 population) | Counties | Residents | Service establishments | Residents per establishment | Establishments per 1,000 | Service jobs per 100 residents |
|---|---|---|---|---|---|---|
| Under 25,000 | 10 | 163,706 | 1,357 | 121 | 8.3 | 7.4 |
| 25,000 to 99,999 | 20 | 953,480 | 10,117 | 94 | 10.6 | 11.5 |
| 100,000 to 249,999 | 8 | 1,265,550 | 15,975 | 79 | 12.6 | 16.4 |
| 250,000 and up | 8 | 3,096,095 | 49,826 | 62 | 16.1 | 22.7 |
| All counties | 46 | 5,478,831 | 77,275 | 71 | 14.1 | 18.9 |

Which South Carolina counties count as rural?
For this analysis, the smallest tier is the 10 counties with fewer than 25,000 residents in 2024: Abbeville, Allendale, Bamberg, Barnwell, Calhoun, Fairfield, Hampton, Lee, McCormick and Saluda. The next tier, 25,000 to 99,999, has 20 counties, including Orangeburg, Greenwood, Georgetown, Oconee and Kershaw.
Population size is a simple stand-in for rural. Some mid-size counties include a small city and wide rural areas, and some small counties sit next to a metro. Calhoun and Saluda, for example, border the Columbia area. The tier groupings are meant to show a pattern, not to label any single county.
At the other end, Charleston County has the lowest ratio in the state, 40 residents per service establishment, followed by Beaufort and Georgetown at 49 each. All three are coastal counties where tourism, second homes and retirees add demand that a resident count does not capture. Greenville (56) and Horry (61) round out the five lowest. A low ratio means more choice for customers and more competition for each business.
Where are doctors, dentists and lawyers in short supply?
Health care offices are the clearest gap. Using published Census counts, the smallest counties have 1.9 physician offices per 10,000 residents and 0.9 dental offices, compared with 5.0 and 3.6 in the largest counties. Chiropractic offices drop from 1.4 per 10,000 in the largest counties to 0.2 in the smallest.
Law offices break the pattern. The smallest counties have 3.2 per 10,000 residents, slightly more than the 2.8 in the 25,000 to 99,999 tier, though still well below the 5.9 in the largest counties. General auto repair is the most even: about 1.5 to 2.0 shops per 10,000 residents in every tier, because people need their cars fixed close to home.
- Counties with fewer than three published employer dental offices: Abbeville, Allendale, Calhoun, Fairfield, Lee, McCormick and Union.
- Counties with fewer than three published employer law offices: McCormick and Saluda.
- The highest ratios in the state are in McCormick (164 residents per service establishment), Edgefield (158), Marlboro (155), Saluda (148) and Lee (148). Laurens County, with 70,545 people, has 131.

Are rural South Carolina counties growing?
Mostly not. The median county under 25,000 people lost 1.3% of its population between the April 2020 base and July 2024, according to Census estimates. The median county of 250,000 or more grew 8.0%, and the median county of 100,000 to 249,999 grew 6.4%.
That trend matters for anyone deciding where to open a second location or hire. Demand in the largest counties is growing, and so is competition. Demand in the smallest counties is flat or shrinking, but residents still need care, legal help and repairs, and they have fewer local choices.
| County size | Median county growth, 2020 to 2024 | Tier total growth |
|---|---|---|
| Under 25,000 | -1.3% | -0.7% |
| 25,000 to 99,999 | 1.3% | 2.8% |
| 100,000 to 249,999 | 6.4% | 6.3% |
| 250,000 and up | 8.0% | 9.2% |

What this means for service businesses
Fewer local providers means rural residents travel, wait or go without. For a business, that is an underserved market, but reaching it depends on how the service is delivered and how people find you.
A few practical moves follow from the numbers. A physical therapy group in Florence or Orangeburg can reach patients in neighboring small counties with clear driving directions, evening hours and online booking, so a 40-minute drive feels planned rather than a gamble. A law firm can offer phone or video consultations so a first meeting does not require a trip. A mobile detailing, pet grooming or home health business can list service areas that include small counties where few competitors operate.
Small-town businesses face the reverse question. With fewer residents nearby, a dental office in a county of 20,000 often grows by drawing patients from the next county over or by keeping current patients longer. Reminders, recall campaigns and easy rebooking matter more when the pool of new customers is small.
Monvell's Consulting work often starts with this kind of market sizing, and our Marketing team builds the service area and location content that helps residents in smaller counties find you.
- Map where your current customers live by ZIP code or county before deciding where to market.
- Check the residents per establishment ratio for your industry in each county you could serve.
- Offer remote first steps (phone, video, online forms) when customers would otherwise drive a long way.
- Write service area pages for nearby small counties only when you truly serve them, with real details.
How we did this
Datasets: U.S. Census Bureau County Business Patterns (CBP) 2023, county file for all U.S. counties (released June 2025), and Census Population Estimates Vintage 2024 county totals (co-est2024-alldata). Employment in CBP is for the week of March 12, 2023.
Definitions: service establishments are employer establishments in NAICS sectors 51, 52, 53, 54, 56, 61, 62, 71, 72 and 81. Specific business types use six-digit NAICS codes 621111 (offices of physicians, except mental health), 621210 (dentists), 621310 (chiropractors), 621340 (physical, occupational and speech therapists and audiologists), 541110 (lawyers), 541211 (CPA offices), 812112 (beauty salons) and 811111 (general automotive repair).
Method: we assigned each county to a tier by its July 1, 2024 population, summed establishments, employment and population within each tier, and divided. Growth uses the April 1, 2020 estimates base and the July 1, 2024 estimate. Establishments the Census assigns to a statewide category (employers without a fixed county location) are excluded, so county totals sum to 77,275 rather than the statewide 77,948.
Limits: CBP counts only businesses with paid employees, so solo practitioners and other nonemployer businesses are missing. The Census does not publish a cell with fewer than three establishments, so small-county counts for specific business types are floors, and a missing value can mean zero, one or two. Employment figures include noise added by the Census to protect confidentiality. Business counts are for 2023 and population for 2024. County size is a simple proxy for rural and does not use official rural definitions.
