From 1913 until 1933, the 2nd district covered much of northeastern South Dakota, including the cities of Aberdeen, Brookings, Huron, and Watertown. When South Dakota's 3rd congressional district was eliminated after the 1930 census, the 2nd district was relocated to cover all of the counties in South Dakota west of the Missouri River. Population changes eventually moved the district's boundaries further east.
