The 1st district (Blue) picks up Northampton and some other nearby towns, smoothing the boarder with the second.
The 2nd District (Green) makes up for the loss by grabbing Franklin, Attleboro and some other towns in that area.
The 3rd District (Purple) retains its Worcester and Fall River anchors but otherwise shifts to the East picking up such towns as Foxborough and Taunton.
The 4th District (Red) likewise shifts east, while retaining New Bedford and Frank’s hometown Newton. Gains include Brockton, Bridgewater, Dedham and portions of Boston.
The 5th District (Gold) is mostly unchanged, adding Marlborough and a couple other towns.
The 6th District (Teal) also changes little, though it does gain Woburn, Winthrop and Revere from the 7th.
The 7th District (Gray) makes up for these losses by diving South, gaining such towns as Needham, Dover and Easton.
The 8th District (Periwinkle) gains most of Southie, Roslindale, and Milton. It loses Allston/Brighton to the 4th. It retains its majority-minority status at 49% non-hispanic white, which is about the same as it is currently.
The old 10th District (Cyan), now redesignated the 9th, gains the rest of Southie, the white parts of Dorchester, Braintree and a couple other towns. (Yes I split Lynch’s South Boston base.)
The tool I used to create this map is Dave’s Redistricting App.
I created a map of all the towns in Massachusetts using the app as well, which is immensely helpful, since it only shows city lines and not town lines. If anyone wants this, shoot me an email and I’ll send it to you.
