What the 2020 Census is reporting about Iowa, Nebraska and South Dakota


SIOUX CITY (AP) - The Census Bureau is releasing the first data from its 2020 headcount. Overall, the 2020 Census says the population of the United States is 331,449,281 and that the 7.4% increase over the last decade is the second slowest ever.

But what is it saying about Siouxland's three states?


Census data says Iowa continued to see slow population growth in 2020, with the state population growing 4.7%.

While the state held on to all four congressional districts, the muted population trend could mean the loss of one of those U.S. House seats in the future.

The latest figures in Iowa reflect a century of typically slow growth, and later data likely will show a shift from rural areas to the state’s largest cities has continued.

The Census data enables states to determine the number of congressional seats they’ll have for the next decade but officials will need to wait for more detailed data to redraw congressional and legislative boundaries.


Nebraska’s population grew at the same rate as the rest of the nation for the first time in at least 120 years, breaking the cycle in which the state consistently trailed the United States average.

Census numbers show Nebraska’s population increased 7.4% between 2010 and 2020, matching the national growth rate in the same period. The state had grown at slower pace every decade since at least 1900.

David Drozd of the University of Nebraska at Omaha’s Center for Public Affairs Research says he had expected Nebraska’s growth to slightly lag the national growth rate. Although a lot could change over the next decade, Drozd says Nebraska’s growth leaves it well-positioned to maintain its three U.S. House seats beyond 2030.

South Dakota

South Dakota’s population increase of 8.9% since 2010, ranked the 16th-highest in the nation.

South Dakota's population increase by 72,487 people since 2010, bringing the total to 886,667. It remained the fifth-least populated state in the United States.

South Dakota’s growth rate outpaced neighboring states Nebraska, Iowa and Minnesota.

Northern neighbor North Dakota recorded the region’s highest percentage growth of 15.8%.

In South Dakota, a committee of lawmakers will determine new state legislative districts based on detailed Census data set to be released later this year.
