Each row is a county-allocated estimate of U.S. House votes for this district — county returns apportioned onto its boundary, not precinct-counted. “Vote lead” is the estimated local lead here, not necessarily the winner of the full contest.
Centered in urban Honolulu, this district reflects Hawaii's pattern of lopsided Democratic alignment, with dense residential neighborhoods producing some of the state's most consistent partisan lean across election cycles.
Across the recorded series it reached a Democratic high of 63.1 points in 1964 and a Republican high of 16.7 points in 1972. Between 2020 and 2024 the district moved 9.3 points toward the Republican candidate; the 2024 margin was 19.5 points.
A population of 73,200, a 30% non-Hispanic-white share, and a median household income of $97,668 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 1 and State Senate District 5.
