Analysis# South Dakota Population Analysis
South Dakota's 2024 population of 927,192 reflects modest growth relative to national trends, with a 13.88% increase over the past decade placing it 46th among U.S. states. The state's contemporary growth rate contrasts sharply with its peak performance in the 1910s, when South Dakota experienced its highest decadal growth, indicating that population expansion has significantly slowed since that period. With 124 years of available data, South Dakota's trajectory reveals a maturing state economy that attracts less migration pressure than faster-growing regions, particularly in the Mountain West and Sun Belt.
