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. county the IRS recorded sending households to Boulder County (Boulder, Broomfield, CO)
(95 ranked in total).
How the headline figure is computed
The top three units' combined count divided by the combined count of all 95 ranked units.
Universe
Every U.S. county the IRS disclosed a flow with. Counties whose flow fell below the IRS disclosure threshold are absent from the source file altogether, so this ranking is of disclosed flows and its totals are a floor rather than a complete count of movers.
Every figure on this page is computed directly from the dataset named above
by ALEX Intelligence. No figure on this page was written by hand or by a
language model. The query is stated so that anyone can re-run it and obtain
the same table.
