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 ballots cast by 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. Lawrence reported absentee votes countywide. These were distributed by candidate to precincts based on their share of the precinct-level reported vote. The certified precinct report from Minnehaha County adds up to about 500 fewer votes per office than the countywide totals recorded in the official state canvass. This was evidently an oversight in which the preliminary vote count from Minnehaha County was not updated before the final state canvass. The following additional modifications were made to recreate the 2018 precinct boundaries.
