A major high-tax blue state has seen a significant population loss due to domestic out-migration over the last five years, new research found.
Massachusetts recorded a net loss of about 182,000 residents to domestic out-migration from April 2020 to July 2025, according to an analysis of the state's workforce by the Pioneer Institute. The free market think tank noted the population decline is equivalent to losing roughly one and half Cambridges in that period.
"With domestic out-migration levels growing prior to the pandemic and remaining significantly elevated beyond it, it is clear out-migration is a structural phenomenon that is here to stay and not just a byproduct of remote work and the pandemic," the report explained.
"Those leaving tend to be younger, between the ages of 26 and 34, and the loss of their economic activity will affect the state for decades to come," it continued. "Out-migration could lead to population loss and a reduction in the labor force in 2026 as immigration is expected to drop sharply."
