Not enough data to report
Too few tax filers moved to or from Ziebach County, SD, among the smaller county in South Dakota at about 2,322 residents, for the IRS to publish migration figures above its disclosure threshold in the 2022–2023 filing years. To protect taxpayer privacy, the IRS withholds flows that involve too few returns, which most often affects the smallest counties. Figures may appear in other years. The population and local context below come from Census and other federal sources, a separate universe from the IRS filer data. How the data works.
