South Carolina Federal Spending
SC · Rank #31 of 51
South Carolina accounts for a meaningful but mid-tier share of federal contracting: 29 active contractors and $5.2B in federal obligations, or roughly 0.98% of the national total. The state shows up in specific niches rather than across every category.
Why South Carolina Ranks Where It Does
Mid-tier states like South Carolina usually cluster their federal spending around one or two dominant relationships — most often Department of Defense — rather than spreading it broadly. That concentration means a single base closure, contract recompete, or agency reorganization can move the state's total noticeably. Watch the agency panel for early signals of structural shifts.
