Migration

What's in this dataset #

Track where people and income are moving, county by county and state by state, using IRS tax-return migration data back to 2011. See net migration, top origin/destination markets, age and income breakouts, and national percentile rankings — so your AI can tell you not just where people are moving, but how strong that trend is relative to the rest of the country.
