These boundaries took effect in January 2012, and members are based on the results of the November 2018 elections. The name of the statewide datalayers are GOVCOUNCIL2012_POLY and GOVCOUNCIL2012_ARC.
Staff at the Massachusetts General Court Special Joint Committee on Redistricting developed this layer with its contractor, Caliper Corp. (Newton, MA), using Maptitude for Redistricting software. MassGIS appended the 1:100,000 coastline and state outline and added the Councilor's name and party attributes.
The GOVCOUNCIL2012_POLY attribute table has the following fields:
|FIELD NAME||WDTH / TYPE||DESCRIPTION|
|DIST_NUM||16 / C||Numeric district code from redistricting committee|
|DIST_NAME||16 / C||Name of district|
|MEMBER||2 / C||Name of Councilor|
|PARTY||25 / C||Political party of councilor (D = Democrat)|
In the GOVCOUNCIL2012_ARC attribute table, the field OUTLINE is coded as follows:
- 0 = internal district boundaries
- 1 = state
- 2 = coastline
MassGIS will update the layer as needed.
