The South Carolina Mental Health Workforce

Key findings

• South Carolina registers 283.1 active providers per 100,000 residents. That ranks 44 of 51 jurisdictions, below the national 433.5. #
• Charleston County has the state's highest registered density (602.2 per 100k). #
• Counselors are the largest group at 59.2% of South Carolina's registered workforce (US: 43.9%). #
• 842 providers with a South Carolina practice address first entered the NPI registry in 2025, versus 735 in 2019. These are registry entries, not licenses issued. #
• 60% of South Carolina providers share a registered practice location with six or more in-scope providers. #

Providers per 100,000 by county

Providers are allocated to counties from their practice ZIP code. We withhold the rate for one county (Greenwood), where a single practice address holds at least half the providers registered there — typically a regional employer that enrols its whole clinical staff at one headquarters, which inflates that county and thins its neighbours. The same values appear in the table.

Provider-type mix vs the national picture

Each provider counts once under their primary taxonomy; the US share is printed beside each South Carolina figure for comparison.

When South Carolina's providers entered the registry

Active providers by NPI registry-entry year. Registry entry is not licensure. Clinicians typically register when they start billing, so this measures registrations, not the workforce itself. 2026 is a partial year.
