MassGIS Data: 2012 Wards and Precincts

January 2019

* The most current data (2022) is now available *

Wards and Precincts (voting districts) for Massachusetts cities and towns. Voting resources, including your voting location and ward and precinct can be found on the Secretary of the Commonwealth’s website

Table of Contents



Wards are geographic areas used by governments for local elections. These are then further divided into precincts, in which the polling locations for voting are held. In Massachusetts, only cities comprise both wards and precincts; municipalities designated as towns contain one or more precincts and no wards.

MassGIS obtained the data in September 2012 and edited the data in the fall of 2018 to update a few areas in Boston based on data from the city revised in 2016. The layer includes population values from the 2010 U.S. Census.

The layer is named WARDSPRECINCTS_POLY


Staff at the Massachusetts Secretary of the Commonwealth developed this layer with its contractor, DAPA Research, Inc. (Boston, MA) using Maptitude for Redistricting software. The City of Boston revised its boundaries in 2016. MassGIS projected the data and performed QA.


 The Wards and Precincts layer's polygon attribute table contains the following fields:

WP_NAME Ward-precinct name, with city/town name
WARD Ward name (cities only)
PRECINCT Precinct name
DISTRICT Name of district (combination of Ward and Precinct separated by a hyphen for cities; same as Precinct for towns)
