History of district boundaries
After the 2010 census, the 1st district shifted from covering the western and north-central portions of the state to covering the western and south-central portions of the state. Following the 2020 census, the 1st district boundaries did not shift as drastically but moved to cover somewhat less of the western portions of Franklin and Hampshire Counties while encompassing more of Worcester and southeastern Hampshire Counties.
