Covering part of Honolulu's urban core, this district's D+18.5 presidential margin in 2024 reflects the heavily Democratic lean typical of densely populated Hawaii constituencies, where multiethnic working-class and professional households shape the electorate.

A population of 24,409, a 25% non-Hispanic-white share, and a median household income of $100,819 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 17 and State House District 10.
