Fact-check: “Is the population of South Carolina the fastest growing in the country?”
Verdict: Mostly True (88% confidence)
The U.S. Census Bureau's Vintage 2025 estimates (released January 27, 2026) show South Carolina's population grew 1.5% between July 1, 2024 and July 1, 2025 — the highest percentage growth rate of any state. This is the most current completed vintage, making it the authoritative benchmark as of August 2026. The minor qualification is that 'fastest growing' refers to percentage rate, not absolute numeric gain, and South Carolina ranked only 4th by percentage under the prior Vintage 2024 release.
