South Dakota counties with vote centers do not record votes by precinct. For these counties, votes were apportioned to precincts based on their share of the countywide number of active voters registered with the party of the respective candidates. When this method was tested with counties that report votes by precinct the great majority of precincts were within 4% of the actual candidate vote shares. However, a scattering of precincts deviated by as much as 12% from the actual vote shares. These precincts were either in city centers or far outlying areas, signifying that registered Democrats in rural precincts are more likely to vote for Republican candidates than registered Democrats in urban precincts. Douglas, Kingsbury, and Lawrence reported absentee votes countywide. These were distributed by candidate to precincts based on their share of the precinct-level reported vote. The following additional modifications were made to recreate the 2020 precinct boundaries.
