Compared to the national median of $75,920, Boston-Cambridge-Newton pays +10% above, signaling either concentrated employer demand, a cost-of-living premium, or both.

The Boston-Cambridge-Newton pay distribution spans from $58,030 at the 10th percentile to $125,460 at the 90th — a 2.2× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro.

Metro figures capture where you actually work, not just where you live — which matters for commuters. BLS draws metro boundaries from the OMB MSA definitions, so Boston-Cambridge-Newton, MA-NH covers the central city plus outlying counties tied to the metro economically. Remember that OEWS wages reflect base pay only: employer-provided health insurance, retirement matches, stock options, signing bonuses, overtime, and tips are excluded and can add 20-40% to real total compensation. Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide MA data, and peer-metro comparisons — a median is a starting point, not a ceiling.
