Black Population in South Carolina: From Majority to One in Four
What follows is the plate the atlas files as Black Population in South Carolina: From Majority to One in Four. Its table records Black residents of South Carolina, alone or in combination: 1.45 Million; South Carolina's population was majority Black from the colonial era into the early twentieth century: Once the Majority. In South Carolina, a reader who holds the table and this text together has the plate entire.
In South Carolina, the regional series holds its geography whole; the state plates elsewhere in the atlas divide the same ground by state lines. South Carolina holds about 1.45 million Black residents — Black alone or in combination — more than one in four of its people, with Black alone at about 1.34 million, or 26 percent. The general record matters here only as far as it sharpens the local one, which South Carolina's table states plainly.
The Lowcountry and the Gullah-Geechee Coast
In South Carolina, this regional plate reads the same federal material at the scale of the region itself, and the table below carries its published measures. In South Carolina, the coastal Lowcountry holds the state's oldest Black geography. In South Carolina, held against the national pattern, the state's own rows say how its coverage stands.
The Midlands and the Upstate
For South Carolina, the regional series holds its geography whole; the state plates elsewhere in the atlas divide the same ground by state lines. In South Carolina, columbia, the capital at the state's center, is about two-fifths Black and anchors the Midlands with South Carolina's largest Black institutional base: Benedict College and Allen University, the state government workforce, and Fort Jackson's military economy. That is what a benchmark is for in an atlas: not to rank South Carolina, but to locate it.
Growth and Return
Here, on the plate for South Carolina, the regional series holds its geography whole; the state plates elsewhere in the atlas divide the same ground by state lines. In South Carolina, south Carolina is among the faster-growing states in the nation, and its Black population grows on two currents: the coastal and suburban in-migration of retirees and working families — the Charleston and Myrtle Beach corridors and the Charlotte suburbs that spill across the state line at Fort Mill and Rock Hill — and a return migration of Black households to the Midlands and the coast. Locating South Carolina is the benchmark's purpose; ranking it is not.
Composition
Black South Carolinians record indicators near the Southern pattern: income and attainment below national Black averages in the rural counties, near them in Columbia and Charleston's suburbs, with the state's Black professional class concentrated in the capital's public and university sectors and in the health systems of the three metros. The foreign-born share is small. The age structure is comparatively old in the rural Black counties of the corridor of the state's midsection — the former plantation belt running from the coast to Columbia — and young in the growth suburbs, the standard Southern dual structure that the county tables are built to display.
Reading the South Carolina Numbers
South Carolina's profile is the series' study in demographic depth: a state whose Black majority lasted into living memory's grandparents, whose African cultural retention is the strongest on the mainland, and whose contemporary figures — 1.45 million people, more than one in four — describe continuity under transformation. The county profiles, from the sea islands to the Upstate, carry the local account.
Charleston and Columbia receive full profiles in the cities section, and the sea-island communities of the coast are treated in the county profiles accompanying this state account.
A note on this plate's figures, stated once and plainly: Black residents of South Carolina, alone or in combination: 1.45 Million; South Carolina's population was majority Black from the colonial era into the early twentieth century: Once the Majority. In South Carolina, each figure is published by the source named below and rounded as published; the plate's map shades the Black share of the population on the same basis, so the table and the map can be read against each other without conversion.
Two further figures complete the plate's account of South Carolina: Black residents of South Carolina, alone or in combination: 1.45 Million; South Carolina's population was majority Black from the colonial era into the early twentieth century: Once the Majority. The measures above and these together fix the population of South Carolina as this plate describes it — its size, its share, its standing nationally — and the text that surrounds them interprets them without rounding or extension beyond the source.
