Net interstate balance

South Dakota's population in the year to July 2025

On July 1, 2025, South Dakota had an estimated 935,094 residents, 7,984 more than a year earlier (+0.86%). Ranked by that rate of change, it is 12th of the 50 states and DC.

Components of change in the year to July 2025
  • Natural change (births minus deaths)+2,605
  • Net international migration+3,183
  • Net domestic migration (other states)+2,169

All three parts of the change added people: net international migration (3,183), natural change (2,605) and net domestic migration (2,169), largest first. Births outnumbered deaths, 11,299 to 8,694. The remaining 27 is the Census Bureau's residual, change the three parts do not explain.

Net domestic migration came to 2.3 per 1,000 residents, 17th among the 50 states and DC. Counting international arrivals too, net migration was 5.7 per 1,000.

Against the April 2020 estimates base of 886,656, the 2025 estimate is up 5.5%.

The two Census sources disagree on direction: the state-to-state survey counted more departures than arrivals, outside its margin of error, while the 2025 estimate puts net domestic migration at +2,169. Why the two can differ.
