Oregon Senate District 5 covers a slice of the mid-Willamette Valley where population growth has gradually shifted the competitive landscape, with the 2024 presidential result landing at roughly ten points Democratic — close enough to draw serious attention in legislative cycles.
Across the recorded series it reached a Democratic high of 34.5 points in 1964 and a Republican high of 46.2 points in 1904. Between 2020 and 2024 the district moved 1.2 points toward the Democratic candidate; the 2024 margin was 2.9 points.
A population of 140,337, a 82% non-Hispanic-white share, and a median household income of $66,603 describe the district. The district's voting pattern over the last decade is most similar to that of Legislative (Senate) District 24 and State Senate District 16.
