History of district boundaries

After the 2010 census, the third district shifted from covering east-central Worcester County and western Norfolk and Bristol counties to covering northeastern Worcester County, northern and western Middlesex County, and northwestern Essex county. The old 3rd district area was largely split between the updated 2nd and 4th districts. Only Clinton and Marlborough carried over from the old 3rd district.

In the redistricting that occurred after the 2020 census, the boundaries of the third district only changed slightly from its previous iteration.
