Read this carefully: The IRS withholds county-to-county flows below its disclosure threshold, so a county missing from this table is one whose flow was too small to publish, not one nobody moved from. Every total here is a total of disclosed flows and is therefore a floor.

Methodology

Source:
U.S. Internal Revenue Service, Statistics of Income Migration Data, county-to-county inflows, 2022-23
Measure
Households, ranked highest first across every U.S. state the IRS recorded sending households to Williamson County (Williamson, TX) (38 ranked in total).
How the headline figure is computed
The top three units' combined count divided by the combined count of all 38 ranked units.
Universe
Every U.S. state the IRS disclosed at least one county-to-county flow from. Flows below the IRS disclosure threshold are absent from the source file, so the shares here are computed over disclosed flows.
