South Carolina County Population — 2025 PEP

July 1, 2025 resident population estimates for 46 counties. State total (sum of these county estimates): 5,570,274 persons.

Separate 2025 TIGER/Line county boundaries validate county identity; these are not ACS 2024 survey estimates.

Official Vintage 2025 county identities and unsimplified TIGER coordinates; separate-period ACS housing is joined only by exact full GEOID. Original 2020 counts require separately evidenced compatible geography; incompatible observations remain null with reasons. The revised April estimates base is not an original census count; no boundary allocation is invented.

County population and median home value · different vintages

Each point pairs a county’s PEP July 1, 2025 resident population (persons) with its ACS 2024 5-year median owner-occupied home value (B25077, U.S. dollars). These are different reference periods and different statistical programs. This descriptive comparison does not imply causality or matched vintages. Suppressed, missing or invalid ACS estimates are unavailable, not zero and not plotted. A valid zero remains zero.
