Spartanburg County's growth — and what it means for healthcare demand

Spartanburg County is one of the fastest-growing counties in South Carolina. This page assembles the primary-source numbers — population, healthcare employment, provider supply, and nearby development — and is explicit about the step most growth pages skip: population growth is not, by itself, proof that any specific healthcare business or building will succeed.

Key finding: Spartanburg County grew from a 328,000 Census base (April 2020) to 380,857 residents (July 2025) — +16.1% in five years, ~2.95%/yr compounded — while the county's physician and mental-health provider ratios remained worse than state averages. Demand for care is compounding faster than the supply of people who deliver it.

Population: the verified series

Spartanburg County population estimates, 2020–2025 (U.S. Census Bureau, Vintage 2025) Spartanburg County population estimates, 2020–2025 (U.S. Census Bureau, Vintage 2025) 319,488.9 337,687.353 355,885.805 374,084.258 392,282.71 2020 2021 2022 2023 2024 2025 Residents
July 1 estimatePopulationAnnual gain
2020 (April 1 base: 328,000)329,370
2021335,481+6,111
2022346,466+10,985
2023358,924+12,458
2024369,934+11,010
2025380,857+10,923

Our calculations from that series (formulas shown): growth vs the 2020 base = (380,857 − 328,000) ÷ 328,000 = +16.1%; compound annual growth July 2020→July 2025 = (380,857 ÷ 329,370)1/5 − 1 = +2.95%/yr. Census reporting also places Spartanburg among the fastest-growing metropolitan areas in the country in recent vintages. Residents aged 65+ are 17.5% of the county (Census QuickFacts, V2025) — roughly 66,650 people, the age band with the highest healthcare utilization.

Longer-horizon projections reported in South Carolina media anticipate the county adding on the order of +179,000 residents by 2042 (+49%). We cite that as journalism, not as a verified projection — the state Revenue & Fiscal Affairs projection series predates the 2022–2025 surge, and we will replace this with the primary dataset when re-verified.

Healthcare employment: a decade of growth

Education & Health Services employment in the Spartanburg MSA rose from 14.1k (Dec 2015) to 17.5k (July 2026, preliminary) — about +24% (BLS series SMU45439006500000001). The sector grew straight through the pandemic decade; this is capacity being added in response to demand, and it is the labor pool any healthcare operator here would hire from.

The supply side: providers are scarce relative to the state

What is actually being built nearby

Verified development near the Dillon/Skylyn corridor (status as of 2026-08-23 — we distinguish approved from built):

Honest negative: Spartanburg Regional's announced 2023–2026 capital projects (a $55M Union hospital, a ~$180M Fountain Inn expansion, main-campus work) are all elsewhere. We found no announced investment at the Mary Black Campus itself in that window — and also no evidence of service reduction.

What this data does not prove

What could make this analysis wrong

  • County growth may concentrate on the west side (I-85/BMW corridor) rather than the east side where this corridor sits; sub-county allocation is not established here.
  • Provider ratios describe the county, not a trade area; a site-level catchment study would be required for any specific clinical business.
  • Projections beyond 2025 are inherently uncertain; the cited 2042 figure is press-reported, not yet re-verified against the primary dataset.
  • Approved developments (Drayton Townhomes, Beaumont Mill) can be delayed or cancelled; we label construction status and will update.

Where this leads

If you are researching Spartanburg for a healthcare use, the follow-on questions are concrete: what does medical space cost here (market page), what is actually available near the hospital campuses (comparables), and do the economics of owning beat leasing (underwriter)? One currently marketed property that surfaces repeatedly in that chain is 125 Dillon Drive — a vacant former medical office adjacent to the Mary Black Campus at a below-appraisal ask — with significant caveats we document rather than hide.
