Third column names the leading third-party or independent finisher. Source · MIT Election Lab · ICPSR · VEST (precinct-level 2024). Swing · margin change from the prior cycle. vs U.S. · margin relative to the national result that year. Third-party votes in 2012 are allocated from certified county totals by this place's share of each county's two-party vote — that cycle's precinct source records two-party splits. † 2004 sub-county results are estimated: the source's block-level detail for this cycle was unreliable — either county/municipality-level consolidated reporting (COVID-era) or a precinct-to-block allocation that misplaced votes — so the figures are allocated from the constituent county totals in proportion to the place and scaled to certified totals.

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 24.0 points in 2004. 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 68% 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.
