2020 US Census results: South Dakota population 886,667, ranks 46th out of 50 states
SIOUX FALLS, SD (KELO) — From 2010 to 2020, South Dakota’s resident population grew by 72,487, according to the decennial census.
The 2020 U.S. Census reported that South Dakota had a resident population of 886,667, up 72,487 from 814,180 in 2010.
The apportionment population for South Dakota is 887,770, which is 68,009 more than the 2010 population count of 819,761. The apportionment population is a formula defined by Congress applied to the apportionment population to apportion the 435 seats of the United States House of Representatives between states. The distribution population includes the resident population and the overseas population. Overseas population includes U.S. military personnel and federal civilian employees living outside the United States—and their dependents living with them—who may be assigned to a home state.
In 2020, SD had 1,103 overseas residents, up from 5,581 in 2010. You can compare the numbers in the graphs below.
South Dakota’s population is higher than that of Wyoming, Vermont, Alaska, and North Dakota.
Weiwei Zhang, a professor at South Dakota State University and a state demographer, said the 8.9% growth rate from 2010 to 2020 is South Dakota’s highest growth rate since. the 1930s.
“It’s the highest in eight decades and it’s higher than the Midwestern and national averages,” Zhang said. “If you break the growth down into years, our growth in that decade is more even from year to year.”
The 2020 count is the population based on April 1, 2020. The US growth rate was 7.4% and the Midwest growth rate was 3.1%.
Zhang, who is also the state representative for federal-state-cooperative population estimates, said the decennial census is really important, even though there are annual population estimates. She is helping the US Census Bureau review data county by county.
“A lot of these population estimates are constructed from these decennial censuses,” Zhang said. “If we eliminate the base number, the error or margin of error will be retained for another decade.”
She said when county-by-county data becomes available, more policy and program impacts will come from the 2020 census.
“For our state, it is good to see that over the past three decades, the state has grown by an average of 7-8 percent,” Zhang said.
The total population of the United States was 331,449,281. The most populous state was California (39,538,223) and the least populous was Wyoming (576,851). The US growth rate was 7.4% and the Midwest growth rate was 3.1%.
The state that has grown the most numerically since the 2010 census is Texas (up from 3,999,944 to 29,145,505). Utah grew at the highest rate of 18.4% from 2010 to 2020.
The Census Bureau‘s redistricting data, which will include local counts that states need to redraw or “redraw” legislative boundaries, is expected to be completed by September.
