Grafton County, NH → Merrimack County, NH

Reported tax-filing households, individuals, and adjusted gross income that moved from Grafton County, NH to Merrimack County, NH, 2022–2023.

IRS migration data does not represent every U.S. resident (non-filers are underrepresented), a mailing address does not always equal a physical residence, and AGI reflects Year 2 tax returns without proving income was earned after arrival. Use “income moved” or “reported AGI moved,” not “economic impact created.”
