Arrivals out-earn departures — Maine 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.
16 of Maine's counties have published data.
