North Dakota's at-large congressional district

North Dakota's at-large congressional district is the sole congressional district for the state of North Dakota. Based on size, it is the eighth largest congressional district in the nation.

The district is currently represented by Kelly Armstrong.

History
The district was first created when North Dakota achieved statehood on November 2, 1889, electing a single member. Following the 1900 United States census the state was allocated two seats, both of whom were elected from an at large district. Following the 1910 United States census a third seat was gained, with the legislature drawing three separate districts. The third district was eliminated after the 1930 United States census. After the third seat was lost, North Dakota returned to electing two members at-large (statewide).

Following the 1960 United States census two separate districts were created. In 1970, the second district was eliminated following the 1970 United States census and a single at-large district was created. Since 1972, North Dakota has retained a single congressional district.

1889–1913: one seat, then two
From 1889 to 1903, there was one seat, elected at-large statewide. In 1903 a second at-large seat was added, lasting until 1913.

1913–1933: districts only
After the 1910 census, three seats were apportioned among districts: the ND's 1st congressional district, ND's 2nd congressional district, and ND's 3rd congressional district.

1933–1963: two seats
In 1933, following the 1930 census, the delegation was reduced to two seats and the districts were eliminated in favor of a pair of at-large districts, lasting until 1963.

1963–1973: districts again
In 1963, following the 1960 census, the delegation was again split between geographic districts, the ND's 1st congressional district and ND's 2nd congressional district.

1973–present: one seat
In 1973, following the 1970 census, the delegation was reduced to one seat, represented statewide by an at-large district.
