Where Idaho is gaining from other states
Largest net state-to-state changes by county — same basis as the figures above, top eight only. Each city page adds the in-state picture.
Each bar shows that state's in/out split — rows ranked by total volume. The IRS publishes only each county's largest partner states, so smaller streams are left out and these totals run below the headline figures.

Arrivals out-earn departures — Idaho is trading up.
How this works: IRS SOI County-to-County Migration Data, 2022-2023. The IRS compares the address on consecutive tax
returns, so every move here is a real filed household. The headline figures and county lists count moves that
crossed a state line; the five-year chart counts every move, including from abroad. The data publishes annually
with about a two-year lag, misses people who don't file a return, and leaves 39% of moves
unattributed to a specific county, because flows too small to publish are grouped into regional buckets.
43 of Idaho's counties have published data.
