Six states are small enough in population to receive one House seat, so their district is the state. They are the only places in the country where the congressional map and the state map are the same drawing.
| State | Square kilometres | County equivalents |
|---|---|---|
| Alaska | 1,713,379 | 29 |
| Wyoming | 252,843 | 23 |
| South Dakota | 199,542 | 66 |
| North Dakota | 183,987 | 53 |
| Vermont | 24,850 | 14 |
| Delaware | 6,437 | 3 |
Alaska is 266 times Delaware. Both send one member.
What one seat changes
There is no redistricting to argue about, so these six states sit out every mid-decade map fight and every Voting Rights Act case about district lines. There is also no safe seat to retreat into: an at-large member runs statewide every two years, on the same electorate that elects the state's senators, which makes their races behave more like Senate races than House races.
Four of the six also have a Senate seat on the 2026 ballot. Alaska, South Dakota and Wyoming have a governor's race as well, which means three statewide contests on the same ballot with the same electorate and, in practice, largely the same campaign.
Delaware has a Senate race and no governor's race. Vermont has a governor's race and no Senate race, and its governor serves a two-year term, so Vermont runs a statewide executive campaign every single cycle.
