Sioux Falls has added tens of thousands of residents over the past decade, making it one of the fastest-growing mid-sized cities in the region. That population surge, driven partly by refugee resettlement and corporate relocation, is gradually diversifying an electorate that has leaned heavily Republican.
Across the recorded series it reached a Democratic high of 1.5 points in 2008 and a Republican high of 14.4 points in 2004. Between 2020 and 2024 the city moved 2.9 points toward the Republican candidate; the 2024 margin was 6.8 points.
A population of 201,469, a 78% non-Hispanic-white share, and a median household income of $75,970 describe the city. The city's voting pattern over the last decade is most similar to that of Lincoln and Fort Wayne.
