The Short Answer: Nine Districts
In 2026, Massachusetts has nine congressional districts. This number was confirmed following the 2020 U.S. Census and will remain in place for all elections this decade, including the midterms in 2026.
This means Bay State voters will elect nine representatives to serve in the U.S. House of Representatives. Interestingly, the state has maintained this number of seats since the redistricting that followed the 2010 census, which saw its delegation shrink from ten to nine due to slower population growth compared to other states. For now, nine is the magic number.
Apportionment: The National Headcount
The number of districts isn't arbitrary; it's determined by a constitutional process called apportionment. Every ten years, the U.S. Census Bureau conducts a massive nationwide headcount. The results are used to divvy up the 435 seats in the House of Representatives among the 50 states based on their population. States with faster-growing populations can gain seats, while those with slower growth or population decline can lose them. After the 2020 Census, Massachusetts's population growth was stable enough for it to hold onto its nine seats, avoiding a further reduction in its congressional delegation.
Redistricting: Drawing the Local Lines
Once a state knows how many seats it gets, the next step is redistricting—the often-contentious process of drawing the actual district maps. In Massachusetts, this task falls to the state legislature, subject to a veto from the governor. Following the 2020 Census, the Massachusetts General Court got to work, holding hearings and eventually passing a new map. Then-Governor Charlie Baker signed the new congressional map into law on November 22, 2021. These are the district boundaries that were used in the 2022 and 2024 elections and will be used again in 2026.
The Political Landscape of the Nine
Having nine districts is one thing; their political character is another. All nine of Massachusetts's congressional districts are currently held by Democrats, making it one of the largest states with a single-party congressional delegation. The 2021 redistricting process did not significantly alter the political leanings of the districts, keeping them all safely Democratic. The districts range from the urban core of Boston and its dense suburbs to the sprawling, more rural areas of Western Massachusetts. For example, the 1st District covers the western part of the state, including cities like Springfield and Pittsfield, while the 7th and 8th districts are centered on Boston and its immediate surroundings. This deep blue uniformity means that the most significant electoral battles often happen during the Democratic primaries rather than the general election.
