2021 tax returns showed nearly 38,000 Massachusetts residents between the age of 26 and 35 moved out of the state in 2020.

"You expect to see 26- to 35-year-olds move in and out a lot," said Massachusetts Taxpayers Foundation President Doug Howgate. "But the fact that it's the biggest loss sector ... that's a concern for that long-term workforce pipeline."

That kind of loss in the labor force impacts the state's ability to support its economy, he said.
