“Ran ahead” is how far the winning party’s House candidate ran ahead of that party’s presidential margin in the same district. A dash means the House race and the presidential figure were measured on different district lines, so the two cannot be subtracted — both are still shown unchanged.

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 Democratic high of 87.3 points in 1936 and a Republican high of 47.1 points in 1876. Between 2020 and 2024 the district moved 4.4 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.
