BOSTON—Massachusetts lawmakers are preparing to debate and vote on new Statehouse redistricting maps.
The maps of new Massachusetts House and Senate districts are designed in part to increase the political clout of blacks, Latinos and Asian-Americans.
The changes, based on population figures from the 2010 U.S. Census, reflect demographic changes in the state during the past decade.
The maps double the number of districts in the House where minority voters would be in the majority, and would also increase from two to three the number of so-called majority-minority Senate districts.
The House and Senate are expected to vote on the maps during formal sessions on Tuesday.
The Legislature's redistricting committee is also expected to unveil a new congressional map soon. The number of districts is shrinking from 10 to nine.![]()
