Fidelity, State Street, and a deep asset management industry give the city its financial weight. The employed population was 377,807 in 2024, and median household income stood at $97,344 (DataUSA).

Who lives in the 617 region

Boston's median age of 33.3 (DataUSA, 2024) reflects hundreds of thousands of students cycling through, while the permanent professional class concentrates in medicine, research, law, and finance. Over a quarter of residents were born outside the country, and the talent pipeline is the region's real export.

What a 617 number signals to a caller

Area code 617 has been Boston's number since 1947, when it covered the eastern half of Massachusetts, and decades of splits have shrunk it to the urban core, which gives it a certain standing. A 617 number means the city itself, not the 508 or 978 suburbs, and in institutional Boston, Massachusetts that proximity carries weight. Callers describe a guarded phone culture where credentials get checked before conversations open up, and name-dropping the right hospital, lab, or firm is generally expected to do more work than any script.
