Massachusetts's 7th congressional district is a congressional district located in eastern Massachusetts, including roughly three-fourths of the city of Boston and a few of its northern and southern suburbs. The seat is currently held by Democrat Ayanna Pressley.
Due to redistricting after the 2010 census, the borders of the district were changed, with most of the old 7th district redistricted to the new 5th district, and most of the old 8th district comprising the new 7th district. With a Cook Partisan Voting Index rating of D+34, it is the most Democratic district in Massachusetts, a state with an all-Democratic congressional delegation.
According to The Boston Globe and the latest census data, approximately 33 percent of the population of the district were born outside of the United States, with approximately 34 percent of the population white, 26 percent African American, and 21 percent Latino.
In 2019, Ayanna Pressley became the first female and person of color to represent the district as well as the Commonwealth of Massachusetts in Congress.
For the 118th and successive Congresses (based on redistricting following the 2020 census), the district contains all or portions of three counties and 7 municipalities:
Middlesex County (3)
Norfolk County (2)
Suffolk County (2)
