Post-filing deadline analysis
The following analysis covers all state legislative districts up for election in South Dakota in 2024. Information below was calculated on April 24, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.
There were 105 legislative seats up for election this year in South Dakota's legislature—35 in the Senate and 70 in the House. Thirty-six incumbents (three Democrats and 33 Republicans) did not run for re-election. This was the highest retirement rate since 2016 when 42 incumbents (10 Democrats and 32 Republicans) retired. The average number of retirements each year from 2010 to 2022 was 32.
South Dakota legislators are limited to serving four two-year terms in each chamber. Eight members of the Senate were term-limited, and seven members of the House were term-limited.
The number of contested Republican primaries in 2024 (44) was almost double the average for election cycles from 2010 to 2022 (23). This was the highest number of contested Republican primaries since Ballotpedia began tracking this figure in 2010.

Footnotes
- ↑ Ballotpedia defines a seat as open if the incumbent did not file to run for re-election or filed but withdrew and did not appear on any ballot for his or her seat. If the incumbent withdrew from or did not participate in the primary but later chose to seek re-election to his or her seat as a third party or independent candidate, the seat would not be counted as open. If the incumbent retired or ran for a different seat in the same chamber, his or her original seat would be counted as open unless another incumbent from the same chamber filed to run for that seat, in which case it would not be counted as open due to the presence of an incumbent.
