South Dakota

How big is this move, relative to the state?

In the 2022–2023 filing year, about 2,417 more people moved into South Dakota than left (counting tax filers and their dependents) — a net gain of about $258.4M in income (nominal) — in a state of 917,739 people.

The rate lets you compare South Dakota with a stateof any size: it’s the net flow divided by population. The IRS counts tax filers; population counts all residents, so read the rate as a scale indicator, not a literal share of people.

What a dollar is worth here

Prices around South Dakota run about 12% below the national average. In plain terms: $100 spent here buys about what $113 buys in the average American community. The figures below apply that to income, each compared to the U.S. average of $70,002 per person.

Jobs and natural hazards

Net migration by income bracket

Tax-filing households that moved into South Dakota minus those that left, by the adjusted gross income they reported, 2022–2023. Positive means more arrived than left at that income level.

Among the highest earners ($200k+), South Dakota ranks #18 of 51 states for net household migration (+294).

What South Dakota ships and receives

Physical goods shipped between South Dakota and other states, 2022. This is freight, not the migration of people or income shown above.

Goods shipped every five years by the Census Commodity Flow Survey (a sample, so figures are estimates and the smallest flows are withheld). Value is nominal. The totals and partner table above count trade between South Dakota and other states; the goods lists count everything the state ships or receives, including within-state shipments. Compare all states. How the data works.
