The Massachusetts Senate Legislative Districts (2002) datalayer reflects the state Senate district boundaries as defined by Massachusetts General Laws, Chapter 57: Section 3. These 40 districts are those used in the Fall 2002 elections. Names of elected officials are up-to-date as of June 22, 2011. The names of the statewide datalayers are SENATE02_POLY (polygons) and SENATE02_ARC (arcs). This replaces the older SENATE93 layer.
