South Carolina's 1st stretches along the Atlantic coast from Myrtle Beach to Hilton Head, where rapid in-migration has gradually compressed a margin that once ran well above 20 points in presidential contests.
Across the recorded series it reached a Republican high of 18.5 points in 2012. Between 2020 and 2024 the district moved 4.5 points toward the Republican candidate; the 2024 margin was 13.1 points.
A population of 731,126, a 70% non-Hispanic-white share, and a median household income of $90,436 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 11 and Congressional District 1.
The congressional districts whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
