Massachusetts's congressional districts

The Commonwealth's districts since 2013[1]

Massachusetts is currently divided into 9 congressional districts, each represented by a member of the United States House of Representatives. After the 2010 census, the number of Massachusetts's seats was decreased from 10 to 9 due to the State's low growth in population since the year 2000. This mandatory redistricting after the 2010 census eliminated Massachusetts's 10th congressional district, and also caused a major shift in how the state's congressional districts are currently drawn.

Enumeration trends[]

After the 1890 Census and starting with the Fifty-third United States Congress in 1893, Massachusetts Congressional Districts were numbered west to east: with the first district in the west (Berkshire County) and the highest numbered district at Cape Cod.

Before then, the district numeration was not as consistent; sometimes running east to west, other times going counter-clockwise around Boston.
