If you pull up that USCB link, the Census 2000 pop. for MA was 6349097, making a seat in MA equal to roughly 634910 constituents.
The 2009 estimate (yes, it’s just an estimate), is 6593587, making a seat in MA equal to roughly 732621 constituents.
If their county-by-county estimates are right, then Middlesex has lost 0.25 seats, Essex 0.13, Norfolk 0.11, Bristol 0.09.
I figure the 4th, 9th, and 10th become 2 seats.
I suppose it is too much to hope for one suburban district that won’t comprise enough of the parasite class to elect a liberal.
