The Great Sorting: How 25 Years of Demographic Migration Reshaped Massachusetts Communities (2000-2024)

Massachusetts experienced extreme demographic sorting 2000-2024: Dover and Wellesley reached 86% BA+ while Lawrence stayed at 15%—a 71-point education gap. Newton's median income ($176K) is 3.7x Springfield's ($48K). Households with children concentrated in wealthy suburbs (Dover 50%, Newton 33%) while Gateway Cities saw family exodus. These migration patterns preceded—and caused—the 2024 political earthquake, creating distinct community universes that will shape the Commonwealth for decades.

Families researching Massachusetts towns for relocation, parents planning K-12 school priorities, pre-retirees evaluating age-appropriate communities, real estate professionals understanding demographic trajectories, policy analysts studying geographic sorting, anyone wondering where 'people like me' are moving.
