Aurora's rapid demographic diversification — driven by immigrant communities from East Africa, Latin America, and Southeast Asia — has redrawn its electoral map since the early 2000s, turning a reliably Republican suburb into a genuine battleground that now leans left in federal contests.
Across the recorded series it reached a Democratic high of 30.9 points in 2020. Between 2020 and 2024 the city moved 7.8 points toward the Republican candidate; the 2024 margin was 23.1 points.
A population of 394,432, a 42% non-Hispanic-white share, and a median household income of $88,368 describe the city. The city's voting pattern over the last decade is most similar to that of Dallas and Reno.
