The state of Massachusetts has 200 legislative districts. Each district elects one representative. The state Senate has 40 districts and the state House has 160 districts.
Use the interactive map below to find your district.
In Massachusetts, congressional and state legislative district lines are drawn by the state legislature. The lines drawn by the state legislature are subject to veto by the governor.[17]
State statutes require that state legislative district boundaries be contiguous and "reasonably preserve counties, towns, and cities intact, where otherwise possible." There are no such requirements in place for congressional districts.[17]
Gov. Charlie Baker (R) signed the state's new legislative maps into law on November 4, 2021.[18] The state House passed the maps by a vote of 158-1 on October 21, 2021. The state Senate approved the legislative plans on October 27, 2021 by a vote of 36-3. The legislature began consideration of the state's redistricting plans on October 19, 2021.[19] These maps took effect for Massachusetts' 2022 legislative elections.
After the redistricting plans were enacted, Massachusetts Secretary of State William Galvin (D) issued a statement expressing concern regarding how the maps would be implemented: "I am extremely disappointed that these bills were signed into law in their current form and I think it is a devastating blow to the voters of Massachusetts. With local precincts divided multiple ways, it will inevitably lead to chaos at the polls and make it impossible for voters to understand who their elected representatives are."[20] After the legislature approved the maps, State Sen. William Brownsberger (D) said, "It’s a quality final product. We have used every minute we’ve had to keep vetting, to keep adjusting . . . and to respond to input that we’ve received."[21]

According to the U.S. Census Bureau, Massachusetts experienced a 3.1 percent increase in population between 2000 and 2010, with the population rising from approximately 6.35 million to 6.55 million. This was below the national average of 9.7 percent, and Massachusetts lost a Congressional seat as a result of the relatively slow growth.[22][23][24]
The Special Joint Committee on Redistricting conducted the redistricting process.[25] On October 18, 2011, the state legislature released draft state Senate and state House maps. The Senate and House plans were passed on November 1, 2011, and were signed into law by the governor November 3, 2011.[26]

The Tenth Amendment of the U.S. Constitution declares that any power not already given to the federal government is reserved to the states and the people.[34] State governments across the country use this authority to hold legislative sessions where a state's elected representatives meet for a period of time to draft and vote on legislation and set state policies on issues such as taxation, education, and government spending. The different types of legislation passed by a legislature may include resolutions, legislatively referred constitutional amendments, and bills that become law.
The Massachusetts Constitution contains provisions regarding when the Massachusetts General Court, which the Senate is a part of, is to meet. This subject has been the focus of several amendments to the Constitution. Originally, Chapter 1 of the Massachusetts Constitution called for the General Court to convene on the last Wednesday of May. Then, Amending Article X called for legislative sessions to convene yearly on the first Wednesday of January. Later, Amending Article LXXII called for the General Court to meet once every two years, but Amending Article LXXV repealed that amendment. Therefore, the rules that govern when the General Court is to meet are in Amending Article X.
Article X calls for the General Court to convene its regular session on the first Wednesday of January. The session does not dissolve until a new regular session convenes in the next year. Article X specifies that it does not prevent the General Court from meeting at any time that it judges necessary.[35]
Every state legislature throughout the country features its own internal procedures that it uses to govern itself and how it interacts with other parts of state government. Ballotpedia's coverage of internal state legislative procedures includes veto overrides, the role of the legislature in the state budget, procedures for filling membership vacancies, and redistricting.
State legislatures can override governors' vetoes. Depending on the state, this can be done during the regular legislative session, in a special session following the adjournment of the regular session, or during the next legislative session. The rules for legislative overrides of gubernatorial vetoes in Massachusetts are listed below.
How many legislators are required to vote for an override? Two-thirds of members present in both chambers.
| Two-thirds of members present in both chambers must vote to override a veto. If all members are in attendance, this is 107 of the 160 members in the Massachusetts House of Representatives and 27 of the 40 members in the Massachusetts State Senate. Massachusetts is one of 36 states that requires a two-thirds vote from both of its legislative chambers to override a veto. |
Authority: Chapter 1, Article II of the Massachusetts Constitution.
| "But if he have any objection to the passing of such bill or resolve, he shall return the same, together with his objections thereto, in writing, to the senate or house of representatives, in whichsoever the same shall have originated; who shall enter the objections sent down by the governor, at large, on their records, and proceed to reconsider the said bill or resolve. But if after such reconsideration, two thirds of the said senate or house of representatives, shall, notwithstanding the said objections, agree to pass the same, it shall, together with the objections, be sent to the other branch of the legislature, where it shall also be reconsidered, and if approved by two thirds of the members present, shall have the force of a law: but in all such cases, the votes of both houses shall be determined by yeas and nays; and the names of the persons voting for, or against, the said bill or resolve, shall be entered upon the public records of the commonwealth." |
| Massachusetts on |
The state operates on an annual budget cycle. The sequence of key events in the budget process is as follows:[36]
Massachusetts is one of 44 states in which the governor has line item veto authority.[36][37]
The governor is legally required to submit a balanced budget proposal. Likewise, the legislature is legally required to pass a balanced budget.[36]
Every state legislature and state legislative chamber in the country contains several legislative committees. These committees are responsible for studying, amending, and voting on legislation before it reaches the floor of a chamber for a full vote. The different types of committees include standing committees, select or special, and joint.
Ballotpedia covers standing and joint committees. The Massachusetts State Senate has 13 standing committees:
In every state but Delaware, voter approval is required to enact a constitutional amendment. In each state, the legislature has a process for referring constitutional amendments before voters. In 18 states, initiated constitutional amendments can be put on the ballot through a signature petition drive. There are also many other types of statewide measures.
The methods in which the Massachusetts Constitution can be amended:
The process of amending the Massachusetts Constitution is governed by Article XLVIII, Amendments to the Massachusetts Constitution, which is itself the 48th amendment to the state's constitution.
Article 48 allows the constitution to be amended through indirect initiative amendments. It imposes a number of restrictions on such proposed amendments:
The state's general court plays a significant role in the process for an initiated constitutional amendment in Massachusetts:
The Massachusetts General Court may also legislatively refer constitutional amendments. This procedure is defined in Section 1 to 3 of Article LXXXI of the Massachusetts Constitution. According to that section:
The Massachusetts Constitution can also be changed through a constitutional convention and subsequent ratification from the voters.
There have been four constitutional conventions in Massachusetts:
