The Oldest Town in Greater Boston: Gloucester Wins the Median-Age Crown by a Full Decade

Gloucester has the oldest population in Greater Boston with a median age of 51.0 — more than 20 years older than the youngest, Cambridge (30.6). Affluent suburbs cluster near the top (Marblehead 49.6, Lexington 46.8), but the winner is a working fishing port, not a country-club town.
