This polygon dataset represents districts in Massachusetts, which were based on demographic data from the 2010 U.S. Census. They were used for elections in 2012 and beyond until the districts are redrawn. MassGIS maintains the layer and will make updates as needed.

Polygon attribute updates reflecting special elections and vacancies were published on May 29, 2013.
