State Legislature

Massachusetts's state legislative and congressional districts are drawn by the state Legislature by ordinary statute, and are subject to the Governor's veto. The Legislature can override vetoes with a two-thirds vote in each chamber.


In addition to the federal requirements of one person, one vote and the Voting Rights Act, Massachusetts’ state constitution (Amend. CI §§ 1, 2) requires that state legislative be contiguous and preserve political subdivisions. There are no state law requirements for drawing congressional districts.

Public Input

The Massachusetts legislature has released its 2020 redistricting website, where the public can find relevant information and contacts.

While Massachusetts law does not require public hearings, the legislative committee responsible for redistricting held 13 meetings between March and June 2011. The Legislature also launched an interactive website dedicated to redistricting. It is likely that there will be similar opportunities and resources for public input in 2021.



Redistricting in Massachusetts is under single-party control by Democrats because of the party's legislative supermajorities (permitting override of a veto from the Commonwealth's Republican Governor), and the congressional delegation is 9 Democrats and no Republicans. However, the Metric Geometry and Gerrymandering Group has used intensive computer simulations to find that Republicans are so evenly distributed around the state that drawing a Republican congressional district is impossible.

Potential Reform

In the 2020 session, the Massachusetts Legislature considered two similar proposals for an independent commission. S13, a proposed constitutional amendment, would create a seven-member commission to draw congressional, state legislative, and councilor districts under certain criteria and with required public hearings. The maps would then be voted on by the Legislature without chance for amendment. H679, a proposed bill, was essentially the same, but limited only to congressional lines. Both bills received no further action before the Legislature adjourned at the end of 2020.


In 2021, participate in the Legislature’s public input process.

  • Obtain Massachusetts redistricting data from OpenPrecincts.
  • Start to plan out what defines your community – whether it’s a shared economic interest, school districts, or other social or other cultural, historical, or economic interests – and how that can be represented on a map. This will come in handy once the Legislature starts collecting feedback. Use software tools such as Dave's Redistricting App and Districtr to draw district maps showing either (a) what a fair map would look like, or (b) where the community you believe should be better represented is located.
