Professional, Scientific, and Technical Services in South Carolina

Professional, Scientific, and Technical Services (NAICS 541) in South Carolina reports 114,785 workers across 12,611 establishments, with $9.7B of aggregate annual payroll flowing through Census CBP 2023 filings. That represents 1.1% of national employment for this industry — a concentration ratio that tells you whether South Carolina is a primary labor market for this NAICS code or a smaller satellite. A share above 5% signals a meaningful regional cluster; below 1% usually means the state is not a structural fit for this industry at scale.

Wage benchmarking is where state-level data earns its keep. The average annual compensation for Professional, Scientific, and Technical Services employees in South Carolina is $84,302/yr, versus a national average of $107,141/yr. South Carolina pays below the national average for this industry — common in lower cost-of-living states or where the industry has a smaller, less specialized local workforce.

Profitability data is only available at the national level because the IRS Statistics of Income program does not publish state-level margin breakdowns. The national net profit margin for Professional, Scientific, and Technical Services is not reported, and while margins do vary by state, the direction of variance usually follows labor cost and establishment size — both shown above.
