South Dakota Continues to Grow
South Dakota’s rate of population growth has continued to outpace the national average. From 2010-2017, the state’s population grew by 6.8%, while the national growth rate was just 5.5%. Prior to 2010, the national rate of population growth exceeded that in South Dakota, but in recent years South Dakota’s population has grown more quickly than the nation’s.
Annual population growth has been slow but steady, resulting in the large increase from 2010 to 2017. As of 2017, the U.S. Census estimates that the population of South Dakota includes 869,666 people, up less than 1.0% from the population of 861,542 in 2016.
In 2017, South Dakota ranked No. 17 in the nation with a 0.9% growth rate, falling three spots from 2016. Idaho had the fastest growing population in the nation with 2.2% annual population growth. Wyoming had the sharpest decline in population in the country, with a 1.0% annual decrease from 2016-2017.
Within the state of South Dakota, the Sioux Falls metropolitan area -- which was home to an estimated 176,421 of South Dakota’s residents in 2017 -- experienced the fastest population growth from 2016 to 2017, growing by 1.9%. The Rapid City’s metro area population -- which was estimated at 74,421 in 2016 -- grew by 1.4%. Meanwhile, Sioux City and Mitchell experienced declines in population, decreasing by 0.3% and 0.4%, respectively.
There was a great deal in variation across South Dakota’s cities and counties as well. The following are the top three fastest growing counties and cities from 2016-2017:
