U.S. House
Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
Washington's 7th is among the most Democratic-leaning districts in the country, anchored by Seattle's dense urban neighborhoods where the 2024 presidential margin exceeded 70 points — a reflection of the district's concentration of younger, highly educated, and racially diverse residents.
Across the recorded series it reached a Democratic high of 75.1 points in 2020 and a Republican high of 27.4 points in 1924. Between 2020 and 2024 the district moved 0.6 points toward the Republican candidate; the 2024 margin was 74.5 points.
A population of 769,269, a 63% non-Hispanic-white share, and a median household income of $125,152 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 8 and Congressional District 9.
The congressional districts whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
