BLS draws metro boundaries from the OMB MSA definitions, so South Bend-Mishawaka, IN-MI 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 IN data, and peer-metro comparisons — a median is a starting point, not a ceiling.
