Illinois: where millennials are moving
Adults born 1981 to 1996 who lived in a different state one year earlier, from the Census Bureau’s 2024 American Community Survey. These are survey estimates of people, shown with their margins of error.
The Census Bureau's 2024 American Community Survey estimates that about 53,500 adults born 1981 to 1996 moved to Illinois from another state in the prior year, while about 70,300 moved away. That is a net loss of about 16,900 millennials (margin of error plus or minus 9,800), the 3rd largest net loss among the 50 states and D.C..
The largest single source of millennials arriving in Illinois was California, at about 5,000 people (plus or minus 1,700), followed by Texas and Florida.

Why this does not match the IRS view
The All households view counts tax-filing households of every age from 2022 to 2023 IRS records. This view counts individual people in one age group from a 2024 Census survey. They measure different things in different years, so the two sets of numbers are shown side by side and never added together. Census age data stops at the state level, so there is no county detail here. More in the guide.
