What stands out

South Dakota had an estimated population of 924,669 on July 1, 2024, according to the Census Bureau's Population Estimates Program. Since July 2020 that is +4.1 % (36,721 people); since 2010 it is +13.3 %. Migration is the larger driver since 2020: net migration +27,646 against a natural change (births minus deaths) of +8,576. Among the 51 states in the United States, it ranks 46 by population. Values for 2010–2019 and 2020–2024 come from two estimate vintages benchmarked to different censuses; the 2019→2020 step is partly a rebasing.
