Third column names the leading third-party or independent finisher. Source · MIT Election Lab · ICPSR · VEST (precinct-level 2024). Swing · margin change from the prior cycle. vs U.S. · margin relative to the national result that year. Third-party votes in 2012 are allocated from certified county totals by this place's share of each county's two-party vote — that cycle's precinct source records two-party splits. † 2004 sub-county results are estimated: the source's block-level detail for this cycle was unreliable — either county/municipality-level consolidated reporting (COVID-era) or a precinct-to-block allocation that misplaced votes — so the figures are allocated from the constituent county totals in proportion to the place and scaled to certified totals.
Federal officeholders only. State and local officeholders are planned for the next data pass.

Oregon's 4th stretches from Eugene's university hub through the Coast Range to the Pacific, blending Democratic-voting Willamette Valley precincts with rural timber communities—a mix that has compressed once-comfortable Democratic margins to low single digits.
Across the recorded series it reached a Democratic high of 17.7 points in 2008. Between 2020 and 2024 the district moved 0.6 points toward the Republican candidate; the 2024 margin was 12.0 points.
A population of 706,178, a 79% non-Hispanic-white share, and a median household income of $68,838 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 5 and Congressional District 1.
