Delaware has a single at-large congressional district, meaning one representative serves the entire state in the U.S. House of Representatives. As one of the least populous states, Delaware does not have enough residents to warrant multiple districts under the current apportionment.
Delaware’s single seat covers all of its about 990,000 residents counted in the 2020 Census, so every voter in the state shares the same U.S. House member. The at-large seat is on the ballot every two years, next on November 3, 2026, and the winner represents the whole state rather than one district within it.
Delaware is represented by one at-large member because its population supports just a single seat, and the reapportionment that followed the 2020 Census kept it at one. Unlike states with several districts, Delaware has no congressional lines to redraw after each census, so the boundary of its district is simply the state border. To confirm you live in Delaware’s district, use the ZIP code lookup on our home page.
Delaware’s at-large seat is currently held by Lisa Blunt Rochester (D). All House seats are up for election on November 3, 2026.
Delaware is also represented in the U.S. Senate by Lisa Blunt Rochester (D) and Chris Coons (D).
