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 24% of moves unattributed to a specific county, because flows too small to publish are grouped into regional buckets. 9 of Connecticut's counties have published data.
