Note: No state administers IQ tests to its residents. These estimates are proxy conversions from standardized achievement scores (NAEP, SAT, ACT) — an approach popularized by McDaniel's 2006 state-IQ estimates in the journal Intelligence — combined with demographic data. Proxy conversions carry real limitations: SAT/ACT participation rates differ sharply by state and bias comparisons, and the variation within any state dwarfs the differences between states. Figures are shown rounded; decimal precision would overstate what these proxies can support. They say nothing about any individual resident.
About South Carolina's IQ Ranking
South Carolina faces educational challenges common to the Deep South — lower education spending, higher poverty rates, and limited rural educational resources. Charleston's growing tech and tourism sectors and Greenville's manufacturing renaissance are improving outcomes in metro areas, but rural communities lag significantly behind.
What Shapes South Carolina's Cognitive Profile
Along the I-95 corridor sit the rural districts that a documentary made notorious as the Corridor of Shame, plaintiffs in the Abbeville lawsuit that ran more than two decades before the state Supreme Court found only minimal constitutional obligations unmet. Industrial recruitment has pulled the rest of South Carolina in another direction: BMW's Spartanburg plant, the company's largest in the world, Boeing's 787 assembly line in North Charleston, and Michelin's North American headquarters created engineering and advanced manufacturing demand that the technical college system feeds through readySC training partnerships. Clemson's automotive research center in Greenville links directly to the cluster. The Read to Succeed law followed the Southern early literacy template with slower results than the versions in Mississippi and Louisiana. Charleston's small tech scene, sometimes branded Silicon Harbor, continues maturing. Population growth ranks among the fastest in the country, importing retirees and workers in roughly equal measure. The estimated average trails regional leaders while the industrial base keeps tightening the skills market.
