Massachusetts's population in the year to July 2025

On July 1, 2025, Massachusetts had an estimated 7,154,084 residents, 15,524 more than a year earlier (+0.22%). Ranked by that rate of change, it is 39th of the 50 states and DC.

Components of change in the year to July 2025
  • Natural change (births minus deaths)+8,419
  • Net international migration+40,240
  • Net domestic migration (other states)−33,340

Net international migration (40,240) and natural change (8,419) added people, while net domestic migration (33,340) took them away; the gains were the larger side. Births outnumbered deaths, 68,055 to 59,636. The remaining 205 is the Census Bureau's residual, change the three parts do not explain.

Net domestic migration came to minus 4.7 per 1,000 residents, 46th among the 50 states and DC. Counting international arrivals too, net migration was 1.0 per 1,000.

Against the April 2020 estimates base of 7,033,112, the 2025 estimate is up 1.7%.

Both Census sources point the same way: the state-to-state survey counted more departures than arrivals, outside its margin of error, and the 2025 estimate puts net domestic migration at −33,340.
